x86: fsp_support: Correct high mem comment typo

2015-06-04T08:39:39Z

High mem starts at 4 GiB. Signed-off-by: Andrew Bradford Reviewed-by: Bin Meng Acked-by: Simon Glass

x86: Add support for the Simple Firmware Interface (SFI)

2015-04-30T03:02:33Z

This provides a way of passing information to Linux without requiring the full ACPI horror. Provide a rudimentary implementation sufficient to be recognised and parsed by Linux. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: fsp: Use reset_cpu()

2015-04-30T03:02:32Z

Now that reset_cpu() functions correctly, use it instead of directly accessing the port on boards that use a Firmware Support Package (FSP). Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Correct the typo in write_tables()

2015-04-30T00:51:50Z

It should be #ifdef instead of #if. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Check PIRQ routing table sanity in the F segment

2015-04-30T00:51:50Z

Previously the PIRQ routing table sanity check was performed against the original table provided by the platform codes. Now we switch to check its sanity on the final table in the F segment as this one is the one seen by the OS. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Support platform PIRQ routing

2015-04-30T00:51:49Z

On x86 boards, platform chipset receives up to four different interrupt signals from PCI devices (INTA/B/C/D), which in turn will be routed to chipset internal PIRQ lines then routed to 8259 PIC finally if configuring the whole system to work under the so-called PIC mode (in contrast to symmetric IO mode which uses IOAPIC). We add two major APIs to aid this, one for routing PIRQ and the other one for generating a PIRQ routing table. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Write configuration tables in last_stage_init()

2015-04-30T00:51:49Z

We can write the configuration table in last_stage_init() for all x86 boards, but not with coreboot since coreboot already has them. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Install a default e820 table in the __weak install_e820_map()

2015-04-30T00:51:49Z

Create a default e820 table with 3 entries which is enough to boot a Linux kernel. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Remove the old VGA driver

2015-04-30T00:51:48Z

CONFIG_VIDEO_VGA is no longer needed thus remove it. Signed-off-by: Bin Meng Acked-by: Simon Glass

dm: x86: Add a uclass for an Low Pin Count (LPC) device

2015-04-18T17:11:14Z

On x86 systems this device is commonly used to provide legacy port access. It is sort-of a replacement for the old ISA bus. Add a uclass for this, and allow it to have child devices. Signed-off-by: Simon Glass
