* net: nfs: make NFS_TIMEOUT configurableTetsuyuki Kobayashi2012-07-12-0/+7
| | | | | | | NFS_TIMEOUT is constant value defined in net/nfs.c. But sometimes it needs to adjust. This patch enables to override NFS_TIMEOUT by defining CONFIG_NFS_TIMEOUT in a board specific config file. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp>
* Add env vars describing U-Boot target boardStephen Warren2012-07-09-0/+14
| | | | | | | | | | | This can be useful for generic scripts. For example, rather than hard- coding a script to ext2load tegra-harmony.dtb, it could load ${soc}-${board}.dtb and hence not need adjustments to run on multiple boards.

| * powerpc/corenet_ds: Slave reads ENV from master when boot from SRIOLiu Gang2012-04-24-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When boot from SRIO, slave's ENV can be stored in master's memory space, then slave can fetch the ENV through SRIO interface. NOTE: Because the slave can not erase, write master's NOR flash by SRIO interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands. Master needs to: 1. Put the slave's ENV into it's own memory space. 2. Set an inbound SRIO window covered slave's ENV stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode and ENV from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.

| * powerpc/corenet_ds: Slave module for boot from SRIOLiu Gang2012-04-24-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the powerpc processors with SRIO interface, boot location can be configured from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash for u-boot image. The image can be fetched from another processor's memory space by SRIO link connected between them. The processor boots from SRIO is slave, the processor boots from normal flash memory space and can help slave to boot from its memory space is master. They are different environments and requirements: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure SRIO switch system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to SRIO1 or SRIO2 by RCW. 3. RCW should configure the SerDes, SRIO interfaces correctly. 4. Slave must be powered on after master's boot. 5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode locally. For the slave module, need to finish these processes: 1. Set the boot location to SRIO1 or SRIO2 by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot. 4. Slave's u-boot image should be generated specifically by make xxxx_SRIOBOOT_SLAVE_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This defines the basics of a new boot time measurement feature. This allows logging of very accurate time measurements as the boot proceeds, by using an available microsecond counter. To enable the feature, define CONFIG_BOOTSTAGE in your board config file. Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be printed just before handing off to the OS. Most IDs are not named at this stage.

* common/image.c: align usage of fdt_high with initrd_highShawn Guo2012-02-27-0/+8
| | | | | | | | | | | | | | | | | | The commit message of a28afca (Add uboot "fdt_high" enviroment variable) states that fdt_high behaves similarly to the existing initrd_high. But fdt_high actually has an outstanding difference from initrd_high. The former specifies the start address, while the later specifies the end address. As fdt_high and initrd_high will likely be used together, it'd be nice to have them behave same. The patch changes the behavior of fdt_high to have it aligned with initrd_high. The document of fdt_high in README is updated with an example to demonstrate the usage of this environment variable.

The main purpose of this is to deal with a very early panic() which would otherwise cause a silent hang. A new board_pre_console_putc() function is added to the board API. If provided by the board it will be called in the event of console output before the console is ready. This function should turn on all UARTs and spray the character out if it possibly can.

* Introduce generic TPM support in u-bootVadim Bendebury2011-12-07-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPM (Trusted Platform Module) is an integrated circuit and software platform that provides computer manufacturers with the core components of a subsystem used to assure authenticity, integrity and confidentiality. This driver supports version 1.2 of the TCG (Trusted Computing Group) specifications. The TCG specification defines several so called localities in a TPM chip, to be controlled by different software layers. When used on a typical x86 platform during the firmware phase, only locality 0 can be accessed by the CPU, so this driver even while supporting the locality concept presumes that only locality zero is used. This implementation is loosely based on the article "Writing a TPM Device Driver" published on http://ptgmedia.pearsoncmg.com Compiling this driver with DEBUG defined will generate trace of all accesses to TMP registers. This driver has been tested and is being used in three different functional ChromeOS machines (Pinetrail and Sandy Bridge Intel chipsets) all using the same Infineon SLB 9635 TT 1.2 device. A u-boot cli command allowing access to the TPM was also implemented and is being submitted as a second patch.

* powerpc/85xx: clean up and document the QE/FMAN microcode macrosTimur Tabi2011-11-29-0/+38
| | | | | | | | | | | | | | | | | | | | Several macros are used to identify and locate the microcode binary image that U-boot needs to upload to the QE or Fman. Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged.

* e1000: Allow direct access to the E1000 SPI EEPROM deviceKyle Moffett2011-10-28-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a part of the manufacturing process for some of our custom hardware, we are programming the EEPROMs attached to our Intel 82571EB controllers from software using U-Boot and Linux. This code provides several conditionally-compiled features to assist in our manufacturing process: CONFIG_CMD_E1000: This is a basic "e1000" command which allows querying the controller and (if other config options are set) performing EEPROM programming. In particular, with CONFIG_E1000_SPI this allows you to display a hex-dump of the EEPROM, copy to/from main memory, and verify/update the software checksum. CONFIG_E1000_SPI_GENERIC: Build a generic SPI driver providing the standard U-Boot SPI driver interface. This allows commands such as "sspi" to access the bus attached to the E1000 controller. Additionally, some E1000 chipsets can support user data in a reserved space in the E1000 EEPROM which could be used for U-Boot environment storage. CONFIG_E1000_SPI: The core SPI access code used by the above interfaces. For example, the following commands allow you to program the EEPROM from a USB device (assumes CONFIG_E1000_SPI and CONFIG_CMD_E1000 are enabled): usb start fatload usb 0 $loadaddr 82571EB_No_Mgmt_Discrete-LOM.bin e1000 0 spi program $loadaddr 0 1024 e1000 0 spi checksum update Please keep in mind that the Intel-provided .eep files are organized as 16-bit words. When converting them to binary form for programming you must byteswap each 16-bit word so that it is in little-endian form. This means that when reading and writing words to the SPI EEPROM, the bit ordering for each word looks like this on the wire: Time >>> ------------------------------------------------------------------ ... [7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8], ... ------------------------------------------------------------------ (MSB is 15, LSB is 0).

* FAT: Add FAT write featureDonggeun Kim2011-10-26-0/+5
| | | | | | | | | | | | | | In some cases, saving data in RAM as a file with FAT format is required. This patch allows the file to be written in FAT formatted partition. The usage is similar with reading a file. First, fat_register_device function is called before file_fat_write function in order to set target partition. Then, file_fat_write function is invoked with desired file name, start ram address for writing data, and file size.

* fdt: ARM: Add fdtcontroladdr to set device tree address in environmentSimon Glass2011-10-26-0/+4
| | | | | | | | | | This adds support for a new environment variable called 'fdtcontroladdr'. If defined, the hex address is used as the address of the control fdt for U-Boot. Note: I have not changed CONFIG_PRAM section as I already have an outstanding patch on that. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add support for a separate device tree (CONFIG_OF_SEPARATE)Simon Glass2011-10-26-2/+14
| | | | | | | | | This adds support for an FDT to be build as a separate binary file called u-boot.dtb. This can be concatenated with the U-Boot binary to provide a device tree located at run-time by U-Boot. The Makefile is modified to provide this file in u-boot-dtb.bin.

* fdt: Add support for embedded device tree (CONFIG_OF_EMBED)Simon Glass2011-10-26-2/+9
| | | | | | | | | | | | | | | | | This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path. This commit contains my entry for the ugliest Makefile / shell interaction competition. Signed-off-by: Simon Glass <sjg@chromium.org>
