Broadcom-s U-Boot https://git.openwrt.org/project/bcm63xx/u-boot/atom?h=master 2015-08-05T14:44:06Z 2015-08-05T14:44:06Z Simon Glass 2015-08-04T18:33:52Z urn:sha1:476476e73b14696563524cbc2627a4c033ea64da 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.

Add library code to perform these tasks. This includes efi_main() which is the entry point from EFI. U-Boot is built as a shared library.
