2016-03-17x86: Add the root-complex block to common intel registersSimon Glass
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>
2016-03-17x86: Create a common header for Intel register accessSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2016-03-17x86: cpu: Add functions to return the family and steppingSimon Glass
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>
2016-03-17x86: Allow use of serial soon after relocationSimon Glass
At present on x86 machines with use cache-as-RAM, the memory goes away just before board_init_r() is called. This means that serial drivers are no-longer unavailable, until initr_dm() it called, etc. Any attempt to use printf() within this period will cause a hang. To fix this, mark the serial devices as 'unavailable' when it is no-longer available. Bring it back when serial_initialize() is called. This means that the debug UART will be used instead for this period. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2016-03-17dm: timer: Correct timer init ordering after relocationSimon Glass
Commit 1057e6c broke use of the timer with driver model. If the timer is used before relocation, then it becomes broken after relocation. This prevents some x86 boards from booting. Fix it.

2016-03-17x86: Add comments to the SIPI vectorSimon Glass
The Intel SIPI (start-up inter-processor interrupt) vector is the entry point for each secondary CPU (also called an AP - applications processor).

2016-03-17x86: gpio: Correct GPIO setup orderingSimon Glass
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.

2016-03-17x86: Support booting SeaBIOSBin Meng
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.
