2017-04-05board_f: Drop setup_dram_config() wrapperSimon Glass
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 <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2017-04-05board_f: x86: Use checkcpu() for CPU initSimon Glass
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.

2016-11-14x86: Move efi .S files into the 'lib' directorySimon Glass
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 <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-08-05x86: Add helper code for running from EFISimon Glass
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 <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-08-05x86: Handle running as EFI payloadSimon Glass
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 <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-08-05efi: Add 64-bit payload supportSimon Glass
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.

2015-08-05x86: Support building the EFI stubSimon Glass
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 <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-08-05x86: Add relocation and link script for a 64-bit EFI applicationSimon Glass
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 <sjg@chromium.org> Improvements to how the payload is built: Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-08-05x86: Add support for U-Boot as an EFI applicationBen Stoltz
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 <stoltz@google.com> Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
