x86: Add helper code for running from EFI

2015-08-05T14:44:08Z

When U-Boot is running from EFI some of the x86 init is replaced with EFI-specific init. For example, since DRAM has already been set up, we only need to find it, not init it. Add these functions so that boards can easily allow booting from EFI if required. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Handle running as EFI payload

2015-08-05T14:44:08Z

When U-Boot runs as an EFI payload it needs to avoid setting up the CPU again. Also U-Boot currently does not handle interrupts for many devices, so run with interrupts disabled. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

efi: Add 64-bit payload support

2015-08-05T14:44:07Z

Most EFI implementations use 64-bit. Add a way to build U-Boot as a 64-bit EFI payload. The payload unpacks a (32-bit) U-Boot and starts it. This can be enabled for x86 boards at present.

x86: Support building the EFI stub

2015-08-05T14:44:07Z

Add support for building a 32/64-bit EFI stub for x86. This involves building the startup and relocation code for either i386 or x86_64. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add relocation and link script for a 64-bit EFI application

2015-08-05T14:44:06Z

Add a linker script and relocation code for building 64-bit EFI applications. This can be used for the EFI stub. Signed-off-by: Simon Glass Improvements to how the payload is built: Signed-off-by: Bin Meng 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
