This component -* supports a distributed DMA design in which each device can have it's own -* dedicated DMA channel, as opposed to a centralized DMA design. -* A device which uses DMA typically contains two DMA channels, one for -* sending data and the other for receiving data. -* -* This component is designed to be used as a basic building block for -* designing a device driver. It provides registers accesses such that all -* DMA processing can be maintained easier, but the device driver designer -* must still understand all the details of the DMA channel. -* -* The DMA channel allows a CPU to minimize the CPU interaction required to move -* data between a memory and a device. The CPU requests the DMA channel to -* perform a DMA operation and typically continues performing other processing -* until the DMA operation completes. DMA could be considered a primitive form -* of multiprocessing such that caching and address translation can be an issue. -* -* Scatter Gather Operations -* -* The DMA channel may support scatter gather operations. A scatter gather -* operation automates the DMA channel such that multiple buffers can be -* sent or received with minimal software interaction with the hardware. Buffer -* descriptors, contained in the XBufDescriptor component, are used by the -* scatter gather operations of the DMA channel to describe the buffers to be -* processed. -* -* Scatter Gather List Operations -* -* A scatter gather list may be supported by each DMA channel. The scatter -* gather list allows buffer descriptors to be put into the list by a device -* driver which requires scatter gather. The hardware processes the buffer -* descriptors which are contained in the list and modifies the buffer -* descriptors to reflect the status of the DMA operations. The device driver -* is notified by interrupt that specific DMA events occur including scatter -* gather events. The device driver removes the completed buffer descriptors -* from the scatter gather list to evaluate the status of each DMA operation. -* -* The scatter gather list is created and buffer descriptors are inserted into -* the list. Buffer descriptors are never removed from the list after it's -* creation such that a put operation copies from a temporary buffer descriptor -* to a buffer descriptor in the list. Get operations don't copy from the list -* to a temporary, but return a pointer to the buffer descriptor in the list. -* A buffer descriptor in the list may be locked to prevent it from being -* overwritten by a put operation. This allows the device driver to get a -* descriptor from a scatter gather list and prevent it from being overwritten -* until the buffer associated with the buffer descriptor has been processed. -* -* Typical Scatter Gather Processing -* -* The following steps illustrate the typical processing to use the -* scatter gather features of a DMA channel. -* -* 1. Create a scatter gather list for the DMA channel which puts empty buffer -* descriptors into the list. -* 2. Create buffer descriptors which describe the buffers to be filled with -* receive data or the buffers which contain data to be sent. -* 3. Put buffer descriptors into the DMA channel scatter list such that scatter -* gather operations are requested. -* 4. Commit the buffer descriptors in the list such that they are ready to be -* used by the DMA channel hardware. -* 5. Start the scatter gather operations of the DMA channel. -* 6. Process any interrupts which occur as a result of the scatter gather -* operations or poll the DMA channel to determine the status. -* -* Interrupts -* -* Each DMA channel has the ability to generate an interrupt. This component -* does not perform processing for the interrupt as this processing is typically -* tightly coupled with the device which is using the DMA channel. It is the -* responsibility of the caller of DMA functions to manage the interrupt -* including connecting to the interrupt and enabling/disabling the interrupt. -* -* Critical Sections -* -* It is the responsibility of the device driver designer to use critical -* sections as necessary when calling functions of the DMA channel. This -* component does not use critical sections and it does access registers using -* read-modify-write operations. Calls to DMA functions from a main thread -* and from an interrupt context could produce unpredictable behavior such that -* the caller must provide the appropriate critical sections. -* -* Address Translation -* -* All addresses of data structures which are passed to DMA functions must -* be physical (real) addresses as opposed to logical (virtual) addresses. -* -* Caching -* -* The memory which is passed to the function which creates the scatter gather -* list must not be cached such that buffer descriptors are non-cached. This -* is necessary because the buffer descriptors are kept in a ring buffer and -* not directly accessible to the caller of DMA functions. -* -* The caller of DMA functions is responsible for ensuring that any data -* buffers which are passed to the DMA channel are cache-line aligned if -* necessary. -* -* The caller of DMA functions is responsible for ensuring that any data -* buffers which are passed to the DMA channel have been flushed from the cache. -* -* The caller of DMA functions is responsible for ensuring that the cache is -* invalidated prior to using any data buffers which are the result of a DMA -* operation. -* -* Memory Alignment -* -* The addresses of data buffers which are passed to DMA functions must be -* 32 bit word aligned since the DMA hardware performs 32 bit word transfers. -* -* Mutual Exclusion -* -* The functions of the DMA channel are not thread safe such that the caller -* of all DMA functions is responsible for ensuring mutual exclusion for a -* DMA channel. Mutual exclusion across multiple DMA channels is not -* necessary. -* -* NOTES: -* -* Many of the provided functions which are register accessors don't provide -* a lot of error detection. The caller is expected to understand the impact -* of a function call based upon the current state of the DMA channel. This -* is done to minimize the overhead in this component. -* -******************************************************************************/ - -#ifndef XDMA_CHANNEL_H /* prevent circular inclusions */ -#define XDMA_CHANNEL_H /* by using protection macros */ - -/***************************** Include Files *********************************/ - -#include "xdma_channel_i.h" /* constants shared with buffer descriptor */ -#include "xbasic_types.h" -#include "xstatus.h" -#include "xversion.h" -#include "xbuf_descriptor.h" - -/************************** Constant Definitions *****************************/ - -/* the following constants provide access to the bit fields of the DMA control - * register (DMACR) - */ -#define XDC_DMACR_SOURCE_INCR_MASK 0x80000000UL /* increment source address */ -#define XDC_DMACR_DEST_INCR_MASK 0x40000000UL /* increment dest address */ -#define XDC_DMACR_SOURCE_LOCAL_MASK 0x20000000UL /* local source address */ -#define XDC_DMACR_DEST_LOCAL_MASK 0x10000000UL /* local dest address */ -#define XDC_DMACR_SG_DISABLE_MASK 0x08000000UL /* scatter gather disable */ -#define XDC_DMACR_GEN_BD_INTR_MASK 0x04000000UL /* descriptor interrupt */ -#define XDC_DMACR_LAST_BD_MASK XDC_CONTROL_LAST_BD_MASK /* last buffer */ - /* descriptor */ - -/* the following constants provide access to the bit fields of the DMA status - * register (DMASR) - */ -#define XDC_DMASR_BUSY_MASK 0x80000000UL /* channel is busy */ -#define XDC_DMASR_BUS_ERROR_MASK 0x40000000UL /* bus error occurred */ -#define XDC_DMASR_BUS_TIMEOUT_MASK 0x20000000UL /* bus timeout occurred */ -#define XDC_DMASR_LAST_BD_MASK XDC_STATUS_LAST_BD_MASK /* last buffer */ - /* descriptor */ -#define XDC_DMASR_SG_BUSY_MASK 0x08000000UL /* scatter gather is busy */ - -/* the following constants provide access to the bit fields of the interrupt - * status register (ISR) and the interrupt enable register (IER), bit masks - * match for both registers such that they are named IXR - */ -#define XDC_IXR_DMA_DONE_MASK 0x1UL /* dma operation done */ -#define XDC_IXR_DMA_ERROR_MASK 0x2UL /* dma operation error */ -#define XDC_IXR_PKT_DONE_MASK 0x4UL /* packet done */ -#define XDC_IXR_PKT_THRESHOLD_MASK 0x8UL /* packet count threshold */ -#define XDC_IXR_PKT_WAIT_BOUND_MASK 0x10UL /* packet wait bound reached */ -#define XDC_IXR_SG_DISABLE_ACK_MASK 0x20UL /* scatter gather disable - acknowledge occurred */ -#define XDC_IXR_SG_END_MASK 0x40UL /* last buffer descriptor - disabled scatter gather */ -#define XDC_IXR_BD_MASK 0x80UL /* buffer descriptor done */ - -/**************************** Type Definitions *******************************/ - -/* - * the following structure contains data which is on a per instance basis - * for the XDmaChannel component - */ -typedef struct XDmaChannelTag { - XVersion Version;

This allows the device driver to get a -* descriptor from a scatter gather list and prevent it from being overwritten -* until the buffer associated with the buffer descriptor has been processed. -* -* The get and put functions only operate on the list and are asynchronous from -* the hardware which may be using the list of descriptors. This is important -* because there are no checks in the get and put functions to ensure that the -* hardware has processed the descriptors. This must be handled by the driver -* using the DMA scatter gather channel through the use of the other functions. -* When a scatter gather operation is started, the start function does ensure -* that the descriptor to start has not already been processed by the hardware -* and is not the first of a series of descriptors that have not been committed -* yet. -* -* Descriptors are put into the list but not marked as ready to use by the -* hardware until a commit operation is done. This allows multiple descriptors -* which may contain a single packet of information for a protocol to be -* guaranteed not to cause any underflow conditions during transmission. The -* hardware design only allows descriptors to cause it to stop after a descriptor -* has been processed rather than before it is processed. A series of -* descriptors are put into the list followed by a commit operation, or each -* descriptor may be commited. A commit operation is performed by changing a -* single descriptor, the first of the series of puts, to indicate that the -* hardware may now use all descriptors after it. The last descriptor in the -* list is always set to cause the hardware to stop after it is processed. -* -* Typical Scatter Gather Processing -* -* The following steps illustrate the typical processing to use the -* scatter gather features of a DMA channel. -* -* 1. Create a scatter gather list for the DMA channel which puts empty buffer -* descriptors into the list. -* 2. Create buffer descriptors which describe the buffers to be filled with -* receive data or the buffers which contain data to be sent. -* 3. Put buffer descriptors into the DMA channel scatter list such that scatter -* gather operations are requested. -* 4. Commit the buffer descriptors in the list such that they are ready to be -* used by the DMA channel hardware. -* 5. Start the scatter gather operations of the DMA channel. -* 6. Process any interrupts which occur as a result of the scatter gather -* operations or poll the DMA channel to determine the status. This may -* be accomplished by getting the packet count for the channel and then -* getting the appropriate number of descriptors from the list for that -* number of packets. -* -* Minimizing Interrupts -* -* The Scatter Gather operating mode is designed to reduce the amount of CPU -* throughput necessary to manage the hardware for devices. A key to the CPU -* throughput is the number and rate of interrupts that the CPU must service. -* Devices with higher data rates can cause larger numbers of interrupts and -* higher frequency interrupts. Ideally the number of interrupts can be reduced -* by only generating an interrupt when a specific amount of data has been -* received from the interface. This design suffers from a lack of interrupts -* when the amount of data received is less than the specified amount of data -* to generate an interrupt. In order to help minimize the number of interrupts -* which the CPU must service, an algorithm referred to as "interrupt coalescing" -* is utilized. -* -* Interrupt Coalescing -* -* The principle of interrupt coalescing is to wait before generating an -* interrupt until a certain number of packets have been received or sent. An -* interrupt is also generated if a smaller number of packets have been received -* followed by a certain period of time with no packet reception. This is a -* trade-off of latency for bandwidth and is accomplished using several -* mechanisms of the hardware including a counter for packets received or -* transmitted and a packet timer. These two hardware mechanisms work in -* combination to allow a reduction in the number of interrupts processed by the -* CPU for packet reception. -* -* Unserviced Packet Count -* -* The purpose of the packet counter is to count the number of packets received -* or transmitted and provide an interrupt when a specific number of packets -* have been processed by the hardware. An interrupt is generated whenever the -* counter is greater than or equal to the Packet Count Threshold. This counter -* contains an accurate count of the number of packets that the hardware has -* processed, either received or transmitted, and the software has not serviced. -* -* The packet counter allows the number of interrupts to be reduced by waiting -* to generate an interrupt until enough packets are received. For packet -* reception, packet counts of less than the number to generate an interrupt -* would not be serviced without the addition of a packet timer. This counter is -* continuously updated by the hardware, not latched to the value at the time -* the interrupt occurred. -* -* The packet counter can be used within the interrupt service routine for the -* device to reduce the number of interrupts. The interrupt service routine -* loops while performing processing for each packet which has been received or -* transmitted and decrements the counter by a specified value. At the same time, -* the hardware is possibly continuing to receive or transmit more packets such -* that the software may choose, based upon the value in the packet counter, to -* remain in the interrupt service routine rather than exiting and immediately -* returning. This feature should be used with caution as reducing the number of -* interrupts is beneficial, but unbounded interrupt processing is not desirable. -* -* Since the hardware may be incrementing the packet counter simultaneously -* with the software decrementing the counter, there is a need for atomic -* operations. The hardware ensures that the operation is atomic such that -* simultaneous accesses are properly handled. -* -* Packet Wait Bound -* -* The purpose of the packet wait bound is to augment the unserviced packet -* count. Whenever there is no pending interrupt for the channel and the -* unserviced packet count is non-zero, a timer starts counting timeout at the -* value contained the the packet wait bound register. If the timeout is -* reached, an interrupt is generated such that the software may service the -* data which was buffered. -* -* NOTES: -* -* Special Test Conditions: -* -* The scatter gather list processing must be thoroughly tested if changes are -* made. Testing should include putting and committing single descriptors and -* putting multiple descriptors followed by a single commit. There are some -* conditions in the code which handle the exception conditions. -* -* The Put Pointer points to the next location in the descriptor list to copy -* in a new descriptor. The Get Pointer points to the next location in the -* list to get a descriptor from. The Get Pointer only allows software to -* have a traverse the list after the hardware has finished processing some -* number of descriptors. The Commit Pointer points to the descriptor in the -* list which is to be committed. It is also used to determine that no -* descriptor is waiting to be commited (NULL). The Last Pointer points to -* the last descriptor that was put into the list. It typically points -* to the previous descriptor to the one pointed to by the Put Pointer. -* Comparisons are done between these pointers to determine when the following -* special conditions exist. - -* Single Put And Commit -* -* The buffer descriptor is ready to be used by the hardware so it is important -* for the descriptor to not appear to be waiting to be committed. The commit -* pointer is reset when a commit is done indicating there are no descriptors -* waiting to be committed.

A device driver designer must be familiar with the -* details of the IPIF hardware to use this component. -* -* The IPIF hardware provides a building block for all hardware devices such -* that each device does not need to reimplement these building blocks. The -* IPIF contains other building blocks, such as FIFOs and DMA channels, which -* are also common to many devices. These blocks are implemented as separate -* hardware blocks and instantiated within the IPIF. The primary hardware of -* the IPIF which is implemented by this software component is the interrupt -* architecture. Since there are many blocks of a device which may generate -* interrupts, all the interrupt processing is contained in the common part -* of the device, the IPIF. This interrupt processing is for the device level -* only and does not include any processing for the interrupt controller. -* -* A device is a mechanism such as an Ethernet MAC. The device is made -* up of several parts which include an IPIF and the IP. The IPIF contains most -* of the device infrastructure which is common to all devices, such as -* interrupt processing, DMA channels, and FIFOs.

The first -* level, referred to as the device level, contains registers which are for the -* entire device. The second level, referred to as the IP level, contains -* registers which are specific to the IP of the device. The two levels of -* registers are designed to be hierarchical such that the device level is -* is a more general register set above the more specific registers of the IP. -* The IP level of registers provides functionality which is typically common -* across all devices and allows IP designers to focus on the unique aspects -* of the IP. -* -* The interrupt registers of the IPIF are parameterizable such that the only -* the number of bits necessary for the device are implemented.

You have to enable generic SPL configuration options (see +docs/README.SPL) as well as CONFIG_SPL_NET_SUPPORT, +CONFIG_ETH_SUPPORT, CONFIG_SPL_LIBGENERIC_SUPPORT and +CONFIG_SPL_LIBCOMMON_SUPPORT in your board configuration file to build +SPL with support for booting over the network.

Define CONFIG_BOOTCOMMAND for your board to load and run debrick +script after boot: +#define CONFIG_BOOTCOMMAND \ + "setenv autoload no; " \ + "bootp; " \ + "if tftp 80000000 debrick.scr; then " \ + "source 80000000; " \ + "fi" +(Or create additional board configuration with such option). + 3. Build U-Boot as usual + $ make <your_board_name> + You will need u-boot.img and spl/u-boot.bin images to perform +network boot. Copy them to u-boot-restore.img and +u-boot-spl-restore.bin respectively to distinguish this version +(with automatic restore running) from the main one. + + II. Host configuration. + 1. Setup DHCP server (recommended server is ISC DHCPd). + - Install DHCP server and setup it to listen on the interface you +chose to connect to the board (usually configured in +/etc/default/dhcpd or /etc/default/isc-dhcp-server). Make sure there +are no other active DHCP servers in the same network segment. + - Edit your dhcpd.conf and subnet declaration matching the address +on the interface. Specify the range of assigned addresses and bootfile +to use. IMPORTANT! Both RBL and SPL use the image filename provided +in the BOOTP reply but obviously they need different images (RBL needs +raw SPL image -- u-boot-spl-restore.bin while SPL needs main U-Boot +image -- u-boot-restore.img). So you have to configure DHCP server to +provide different image filenames to RBL and SPL (and possibly another +one to main U-Boot). This can be done by checking Vendor Class +Identifier (VCI) set by BOOTP client (RBL sets VCI to "DM814x ROM v1.0" +and you can set VCI used by SPL with CONFIG_SPL_NET_VCI_STRING option, +see above). + - If you plan to use TFTP server on another machine you have to set +server-name option to point to it. + - Here is sample configuration for ISC DHCPd, assuming the interface +used to connect to the board is eth0, and it has address 192.168.8.1: + +subnet 192.168.8.0 netmask 255.255.255.0 { + range dynamic-bootp 192.168.8.100 192.168.8.199; + + if substring (option vendor-class-identifier, 0, 10) = "DM814x ROM" { + filename "u-boot-spl-restore.bin"; + } elsif substring (option vendor-class-identifier, 0, 17) = "AM335x U-Boot SPL" { + filename "u-boot-restore.img"; + } else { + filename "uImage"; + } +} + + 2. Setup TFTP server. + Install TFTP server and put image files to it's root directory +(likely /tftpboot or /var/lib/tftpboot or /srv/tftp). You will need +u-boot.img and spl/u-boot-spl-bin files from U-Boot build directory. + + III. Reflashing (debricking) the board. + 1. Write debrick script. You will need to write a script that will +be executed after network boot to perform actual rescue actions. You +can use usual U-Boot commands from this script: tftp to load additional +files, nand erase/nand write to erase/write the NAND flash. + + 2. Create script image from your script. From U-Boot build directory: + +$ ./tools/mkimage -A arm -O U-Boot -C none -T script -d <your script> debrick.scr + +This will create debrick.scr file with your script inside. + + 3. Copy debrick.scr to TFTP root directory. You also need to copy +there all the files your script tries to load via TFTP. Example script +loads u-boot.img and MLO. You have to create these files doing regular +(not restore_flash) build and copy them to tftpboot directory. + + 4. Boot the board from the network, U-Boot will load debrick script +and run it after boot. diff --git a/drivers/block/systemace.c b/drivers/block/systemace.c index 247cf06..bf29cbb 100644 --- a/drivers/block/systemace.c +++ b/drivers/block/systemace.c @@ -65,8 +65,8 @@ static void ace_writew(u16 val, unsigned off) writeb(val, base + off); writeb(val >> 8, base + off + 1); #endif - } - out16(base + off, val); + } else + out16(base + off, val); } static u16 ace_readw(unsigned off) @@ -83,7 +83,7 @@ static u16 ace_readw(unsigned off) } static unsigned long systemace_read(int dev, unsigned long start, - unsigned long blkcnt, void *buffer); + lbaint_t blkcnt, void *buffer); static block_dev_desc_t systemace_dev = { 0 }; @@ -149,7 +149,7 @@ block_dev_desc_t *systemace_get_dev(int dev) * number of blocks read.
