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: Kconfig: Remove deprecated CONFIG_SYS_EXTRA_OPTIONS Currently all x86 boards still use CONFIG_SYS_EXTRA_OPTIONS to define the text base address. Since it is deprecated, just remove it and use CONFIG_SYS_TEXT_BASE directly. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

x86: chromebook_link: Implement CAR support (cache as RAM) Add support for CAR so that we have memory to use prior to DRAM init. On link there is a total of 128KB of CAR available, although some is used for the memory reference code. 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: 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.

x86: Move CONFIG_SYS_CAR_xxx to Kconfig Move CONFIG_SYS_CAR_ADDR and CONFIG_SYS_CAR_SIZE to Kconfig so that we don't need them in the board configuration file thus the same board configuratoin file can be used to build both coreboot version and bare version.
