x86: Add implementations of setjmp() and longjmp()

2016-10-18T07:58:50Z

Bring in these functions from Linux v4.4. They will be needed for EFI loader support. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add basic support for broadwell

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

x86: Move cache-as-RAM code into a common location

2016-03-17T02:27:24Z

This cache-as-RAM (CAR) code is common to several Intel chips. Create a new intel_common directory and move it in there. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: ivybridge: Remove NORTHBRIDGE_INTEL_SANDYBRIDGE

2015-12-09T09:44:50Z

NORTHBRIDGE_INTEL_SANDYBRIDGE is for sandybridge, not ivybridge. Signed-off-by: Bin Meng Acked-by: Simon Glass Tested-by: Simon Glass

x86: Add a way to call 32-bit code from 64-bit mode

2015-08-05T14:44:07Z

The procedure to drop from 64-bit mode to 32-bit is a bit messy. Add a function to take care of it. It requires identity-mapped pages and that the calling code is running below 4GB. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add support for U-Boot as an EFI application

2015-08-05T14:44:06Z

Add the required x86 glue code. This includes the initial start-up, relocation and jumping to efi_main(). We also need to avoid fiddling with interrupts. Signed-off-by: Ben Stoltz Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add I/O APIC register access routines

2015-07-15T00:03:17Z

I/O APIC registers are addressed indirectly. Add io_apic_read() and io_apic_write() routines to help register access. Two macros for I/O APIC ID and version register offset are also added. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: dm: Clean up cpu drivers

2015-07-15T00:03:15Z

This commit does the following to clean up x86 cpu dm drivers: - Move cpu_x86 driver codes from arch/x86/cpu/cpu.c to a dedicated file arch/x86/cpu/cpu_x86.c - Rename x86_cpu_get_desc() to cpu_x86_get_desc() to keep consistent naming with other dm drivers - Add a new cpu_x86_bind() in the cpu_x86 driver which does exactly the same as the one in the intel baytrail cpu driver - Update intel baytrail cpu driver to use cpu_x86_get_desc() and cpu_x86_bind() Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Refactor PIRQ routing support

2015-06-04T08:39:39Z

PIRQ routing is pretty much common in Intel chipset. It has several PIRQ links (normally 8) and corresponding registers (either in PCI configuration space or memory-mapped IBASE) to configure the legacy 8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing support using device tree and move it to a common place, so that we can easily add PIRQ routing support on a new platform.
