2015-10-21debug_uart: Adjust the declaration of debug_uart_init()Simon Glass
We want to be able to add other common code to this function. So change the driver's version to have an underscore before it, just like _debug_uart_putc(). Define debug_uart_init() to call this version. Update all drivers to this new method. 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.

2015-08-05efi: Add support for loading U-Boot through an EFI stubSimon Glass
It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.
