board_f: Drop setup_dram_config() wrapper

2017-04-05T20:36:51Z

By making dram_init_banksize() return an error code we can drop the wrapper. Adjust this and clean up all implementations. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

board_f: x86: Use checkcpu() for CPU init

2017-04-05T17:55:09Z

At present we misuse print_cpuinfo() do so CPU init on x86. This is done because it is the next available call after the console is enabled. But several arches use checkcpu() instead. Despite the horrible name (which we can fix), it seems a better choice. Adjust the various x86 CPU implementations to move their init code into checkcpu() and use print_cpuinfo() only for printing CPU info. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

x86: Move efi .S files into the 'lib' directory

2016-11-14T22:24:04Z

These files now need to be in a standard place so that they can be located by generic Makefile rules. Move them to the 'lib' directory. Signed-off-by: Simon Glass Signed-off-by: Alexander Graf

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

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
