kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

kconfig: move CONFIG_USE_PRIVATE_LIBGCC to Kconfig The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86. Those architectures should "select" HAVE_PRIVATE_LIBGCC and CONFIG_USE_PRIVATE_LIBGCC should depend on it. Currently, this option is enabled on Tegra boards and x86 architecture. Move the definition from header files to Kconfig.

x86: Add chromebook_link board This board is a 'bare' version of the existing 'link 'board. It does not require coreboot to run, but is intended to start directly from the reset vector.

help
This target is used for running U-Boot on top of Coreboot. In
this case Coreboot does the early inititalisation, and U-Boot
takes over once the RAM, video and CPU are fully running.
U-Boot is loaded as a fallback payload from Coreboot, in
Coreboot terminology. This method was used for the Chromebook
Pixel when launched.

This is the Chromebook Pixel released in 2013. It uses an Intel
i5 Ivybridge which is a die-shrink of Sandybridge, with 4GB of
SDRAM. It has a Panther Point platform controller hub, PCIe
WiFi and Bluetooth. It also includes a 720p webcam, USB SD
reader, microphone and speakers, display port and 32GB SATA
solid state drive. There is a Chrome OS EC connected on LPC,
and it provides a 2560x1700 high resolution touch-enabled LCD
display.

x86: ivybridge: Implement SDRAM init Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in the board directory and the SDRAM SPD information in the device tree. This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>

x86: Build a .rom file which can be flashed to an x86 machine On x86 machines U-Boot needs to be added to a large ROM image which is then flashed onto the target board. The ROM has a particular format so it makes sense for U-Boot to build this image automatically. Unfortunately it relies on binary blobs so we cannot require this for the default build as yet. Create a u-boot.rom output file for this purpose. Signed-off-by: Simon Glass <sjg@chromium.org>

help
Newer higher-end devices have an Intel Management Engine (ME)
which is a very large binary blob (typically 1.5MB) which is
required for the platform to work. This enforces a particular
SPI flash format. You will need to supply the me.bin file in
your board directory.

help
If there is something wrong with SDRAM then the platform will
often crash within U-Boot or the kernel. This option enables a
very simple RAM test that quickly checks whether the SDRAM seems
to work correctly. It is not exhaustive but can save time by
detecting obvious failures.

x86: Rename chromebook-x86 to coreboot Rename this vendor since it is intended to be used on any platform where coreboot runs at reset and then loads U-Boot. So far it is only tested on link. When other boards are supported it is likely that we will need to move to multiple board names, all under the 'coreboot' vendor. So while it would be possible to remove the vendor for now, that would be short-sighted. Suggested-by: Bin Meng <bmeng.cn@gmail.com> Signed-off-by: Simon Glass <sjg@chromium.org>
