x86: Add common SDRAM-init code

2016-03-17T02:27:27Z

The code to call the memory reference code is common to several Intel CPUs. Add common code for performing this init. Intel calls this 'Pre-EFI-Init' (PEI), where EFI stands for Extensible Firmware Interface. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Move common PCH code into a common place

2016-03-17T02:27:27Z

The SATA indexed register write functions are common to several Intel PCHs. Move this into a common location. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add a function to set the IOAPIC ID

Add a function to set the ID in the IOAPIC. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: broadwell: Add support for SDRAM setup

2016-03-17T02:27:26Z

Broadwell uses a binary blob called the memory reference code (MRC) to start up its SDRAM. This is similar to ivybridge so we can mostly use common code for running this blob. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: broadwell: Add power-control support

2016-03-17T02:27:26Z

Broadwell requires quite a bit of power-management setup. Add code to set this up correctly. Signed-off-by: Simon Glass Acked-by: Bin Meng [squashed in http://patchwork.ozlabs.org/patch/598373/] Signed-off-by: Bin Meng

x86: broadwell: Add an LPC driver

2016-03-17T02:27:26Z

Add a driver for the broadwell LPC (low-pin-count peripheral). This mostly uses common code. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: broadwell: Add a pinctrl driver

2016-03-17T02:27:26Z

GPIO pins need to be set up on start-up. Add a driver to provide this, configured from the device tree. The binding is slightly different from the existing ICH6 binding, since that is quite verbose. The new binding should be just as extensible. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: broadwell: Add a PCH driver

2016-03-17T02:27:25Z

Add a driver for the broadwell low-power platform controller hub. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: Add basic support for broadwell

2016-03-17T02:27:25Z

This adds the broadwell architecture, with the CPU driver and some useful header files. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: Add support for running Intel reference code

2016-03-17T02:27:25Z

Intel has invented yet another binary blob which firmware is required to run. This is run after SDRAM is ready. It is linked to load at a particular address, typically 0, but is a relocatable ELF so can be moved if required. Add support for this in the build system. The file should be placed in the board directory, and called refcode.elf. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
