* x86: Add the root-complex block to common intel registersSimon Glass2016-03-17-5/+4
| | | | | | | | This is similar to MCH in that it is used in various drivers. Add it to the common header. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Create a common header for Intel register accessSimon Glass2016-03-17-3/+15
| | | | | | | | | | | | | | There are several blocks of registers that are accessed from all over the code on Intel CPUs. These don't currently have their own driver and it is not clear whether having a driver makes sense. An example is the Memory Controller Hub (MCH). We map it to a known location on some Intel chips (mostly those without FSP - Firmware Support Package). Add a new header file for these registers, and move MCH into it.

* x86: cpu: Add functions to return the family and steppingSimon Glass2016-03-17-0/+14
| | | | | | | | These two identifiers can be useful for drivers which need to adjust their behaviour depending on the CPU family or stepping (revision). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Add comments to the SIPI vectorSimon Glass2016-03-17-0/+1
| | | | | | | | | The Intel SIPI (start-up inter-processor interrupt) vector is the entry point for each secondary CPU (also called an AP - applications processor). The assembler and C code are linked, so add comments to indicate this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* x86: gpio: Correct GPIO setup orderingSimon Glass2016-03-17-0/+5
| | | | | | | | | | | | | The Intel GPIO driver can set up the GPIO pin mapping when the first GPIO is probed. However, it assumes that the first GPIO to be probed is in the first GPIO bank. If this is not the case then the init will write to the wrong registers. Fix this. Also add a note that this code is deprecated. We should move to using device tree instead.

* x86: Support booting SeaBIOSBin Meng2016-03-17-0/+3
| | | | | | | | | | | | | | | SeaBIOS is an open source implementation of a 16-bit x86 BIOS. It can run in an emulator or natively on x86 hardware with the use of coreboot. With SeaBIOS's help, we can boot some OSes that require 16-bit BIOS services like Windows/DOS. As U-Boot, we have to manually create a table where SeaBIOS gets system information (eg: E820) from. The table unfortunately has to follow the coreboot table format as SeaBIOS currently supports booting as a coreboot payload.
