* powerpc/T4240QDS/eth: some fix for XFIShaohui Xie2014-08-20-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs of serdes2 are routed to a SFP+ cages, which to house fiber cable or direct attach cable(copper), the copper cable is used to emulate the 10GBASE-KR scenario. So, for XFI usage, there are two scenarios, one will use fiber cable, another will use copper cable. For fiber cable, there is NO PHY, while for copper cable, we need to use internal PHY which exist in Serdes to do auto-negotiation and link training, which implemented in kernel. We use hwconfig to define cable type for XFI, and fixup dtb based on the cable type. For copper cable, set below env in hwconfig: fsl_10gkr_copper:<10g_mac_name> the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports, if a given 10G port will use the copper cable for 10GBASE-KR, set the <10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be assumed to be used for the port. For ex. if four XFI ports will both use copper cable, the hwconfig should contain: fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2 For fiber cable: 1. give PHY address to a XFI port, otherwise, the XFI ports will not be available in U-boot, there is no PHY physically for XFI when using fiber cable, this is just to make U-boot happy and we can use the XFI ports in U-boot. 2. fixup dtb to use fixed-link in case of fiber cable which has no PHY. Kernel requests that a MAC must have a PHY or fixed-link. When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface. Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56 is not valid any longer. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | Remove the verified boot limitation that only allows a single RSA public exponent of 65537 (F4). This change allows use with existing PKI infrastructure and has been tested with HSM-based PKI. Change the configuration OF tree format to store the RSA public exponent as a 64 bit integer and implement backward compatibility for verified boot configuration trees without this extra field.

| | | | | | | | | | | | | | | | | | | | | | Some devices (particularly bus devices) must track their children, knowing when a new child is added so that it can be set up for communication on the bus.

* | dm: Introduce per-child data for devicesSimon Glass2014-07-23-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Some device types can have child devices and want to store information about them. For example a USB flash stick attached to a USB host controller would likely use this space. The controller can hold information about the USB state of each of its children. The data is stored attached to the child device in the 'parent_priv' member. It can be auto-allocated by dm when the child is probed. To do this, add a per_child_auto_alloc_size value to the parent driver. Signed-off-by: Simon Glass <sjg@chromium.org>
* | dm: Add functions to access a device's childrenSimon Glass2014-07-23-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices can have childen that can be addressed by a simple index, the sequence number or a device tree offset. Add functions to access a child in each of these ways. The index is typically used as a fallback when the sequence number is not available. For example we may use a serial UART with sequence number 0 as the console, but if no UART has sequence number 0, then we can fall back to just using the first UART (index 0). The device tree offset function is useful for buses, where they want to locate one of their children. The device tree can be scanned to find the offset of each child, and that offset can then find the device. Signed-off-by: Simon Glass <sjg@chromium.org>
* | dm: Provide a function to scan child FDT nodesSimon Glass2014-07-23-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At present only root nodes in the device tree are scanned for devices. But some devices can have children. For example a SPI bus may have several children for each of its chip selects. Add a function which scans subnodes and binds devices for each one. This can be used for the root node scan also, so change it. A device can call this function in its bind() or probe() methods to bind its children. Signed-off-by: Simon Glass <sjg@chromium.org>

* | dm: Introduce device sequence numberingSimon Glass2014-07-23-6/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In U-Boot it is pretty common to number devices from 0 and access them on the command line using this numbering. While it may come to pass that we will move away from this numbering, the possibility seems remote at present. Given that devices within a uclass will have an implied numbering, it makes sense to build this into driver model as a core feature. The cost is fairly small in terms of code and data space. With each uclass having numbered devices we can ask for SPI port 0 or serial port 1 and receive a single device. Devices typically request a sequence number using aliases in the device tree. These are resolved when the device is probed, to deal with conflicts. Sequence numbers need not be sequential and holes are permitted. At present there is no support for sequence numbers using static platform data. It could easily be added to 'struct driver_info' if needed, but it seems better to add features as we find a use for them, and the use of -1 to mean 'no sequence' makes the default value somewhat painful.

* | dm: Allow drivers to be marked 'before relocation'Simon Glass2014-07-23-12/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver model currently only operates after relocation is complete. In this state U-Boot typically has a small amount of memory available. In adding support for driver model prior to relocation we must try to use as little memory as possible. In addition, on some machines the memory has not be inited and/or the CPU is not running at full speed or the data cache is off. These can reduce execution performance, so the less initialisation that is done before relocation the better. An immediately-obvious improvement is to only initialise drivers which are actually going to be used before relocation. On many boards the only such driver is a serial UART, so this provides a very large potential benefit. Allow drivers to mark themselves as 'pre-reloc' which means that they will be initialised prior to relocation. This can be done either with a driver flag or with a 'dm,pre-reloc' device tree property. To support this, the various dm scanning function now take a 'pre_reloc_only' parameter which indicates that only drivers marked pre-reloc should be bound.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-0/+54
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.
