x86: link: Add a config for 64-bit U-Boot Add a new board config which uses 64-bit U-Boot. This is not fully functional but is it a start. Missing features: - SDRAM sizing - Booting linux - EFI support - SCSI device init (and others) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

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. This initial commit has place holders for a wide range of features. These will be added in follow-on patches and series. So far it cannot be booted as there is no ROM image produced, but it does build without errors. Signed-off-by: Simon Glass <sjg@chromium.org>

x86: Make ROM_SIZE configurable in Kconfig Currently the ROM_SIZE is hardcoded to 8MB in arch/x86/Kconfig. This will not be the case when adding additional board support. Hence we make ROM_SIZE configurable (512KB/1MB/2MB/4MB/8MB/16MB) and have the board Kconfig file select the default ROM_SIZE.

x86: kconfig: Let board select SPI flash Only a specific type of SPI flash exists on a board, having board Kconfig to select the SPI flash seems to make more sense. Other flash types are not necessary except coreboot, which implies all available flash drivers there. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

x86: Emit post codes in startup code for Chromebooks On x86 it is common to use 'post codes' which are 8-bit hex values emitted from the code and visible to the user. Traditionally two 7-segment displays were made available on the motherboard to show the last post code that was emitted. This allows diagnosis of a boot problem since it is possible to see where the code got to before it died. On modern hardware these codes are not normally visible. On Chromebooks they are displayed by the Embedded Controller (EC), so it is useful to emit them. We must enable this feature for the EC to see the codes, so add an option for this.
