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.

x86: Support QEMU x86 targets

2015-06-04T08:39:38Z

This commit introduces the initial U-Boot support for QEMU x86 targets. U-Boot can boot from coreboot as a payload, or directly without coreboot.

x86: Add multi-processor init

2015-04-30T22:13:38Z

Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader. Add the required support to U-Boot to init additional APs. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
