* x86: Add queensbay fsp patch information in README.x86Bin Meng2015-03-24-0/+7
| | | | | | | | | | | The FSP release version 001 for Intel Queensbay has a bug which could cause random endless loop during the FspInit call. This bug was published by Intel although Intel did not describe any details. Describe this information in the x86 doc so that U-Boot Queensbay support is invulnerable.

* x86: Add support for Intel Minnowboard MaxSimon Glass2015-02-06-5/+42
| | | | | | | | | | | | | | This is a relatively low-cost x86 board in a small form factor. The main peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800 series CPU. So far only the dual core 2GB variant is supported. This uses the existing FSP support. Binary blobs are required to make this board work. The microcode update is included as a patch (all 3000 lines of it).

* x86: Add some documentation on how to port U-Boot on x86Simon Glass2015-02-06-0/+64

* x86: Add an option to enabling building a ROM fileSimon Glass2015-02-05-4/+6
| | | | | | | | | | | Rather than requiring the Makefile to be modified, provide a build option to enable the ROM to be built. We cannot do this by default since it requires binary blobs. Without these the build will fail. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* x86: Add an 'mtrr' command to list and adjust MTRRsSimon Glass2015-01-13-1/+17
| | | | | | | | | | | | | It is useful to be able to see the MTRR setup in U-Boot. Add a command to list the state of the variable MTRR registers and allow them to be changed. Update the documentation to list some of the available commands. This does not support fixed MTRRs as yet. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Bin Meng <bmeng.cn@gmail.com>
