* x86: Emit post codes in startup code for ChromebooksSimon Glass2014-11-21-1/+38
| | | | | | | | | | | | | | | | 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: Build a .rom file which can be flashed to an x86 machineSimon Glass2014-11-21-0/+13
| | | | | | | | | | | | 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>
* x86: Add chromebook_link boardSimon Glass2014-11-21-0/+298
| | | | | | | | | | | | 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>
