x86: Enable EFI loader support

2016-11-14T22:24:04+00:00

Enable this so that EFI applications (notably grub) can be run under U-Boot
on x86 platforms.

At present the 'hello world' EFI application is not supported for the
qemu-x86_efi_payload64 board. That board builds a payload consisting of a
64-bit header and a 32-bit U-Boot, which is incompatible with the way the
EFI loader builds its EFI application. The following error is obtained:

x86_64-linux-ld.bfd: i386 architecture of input file
   `lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output

This could be corrected with additional Makefile rules. For now, this
feature is disabled for that board.

efi_loader: fix depends on line of EFI_LOADER

2016-11-14T22:24:02+00:00

This line is shown as

   depends on (ARM64 ||\302\240ARM) && OF_LIBFDT

on my Emacs.  Use ASCII characters only.

Assuming it is (ARM64 || ARM), remove the redundancy.
Unlike Linux, CONFIG_ARM includes CONFIG_ARM64 in U-Boot.

efi_loader: Add bounce buffer support

2016-05-27T19:39:48+00:00

Some hardware that is supported by U-Boot can not handle DMA above 32bits.
For these systems, we need to come up with a way to expose the disk interface
in a safe way.

This patch implements EFI specific bounce buffers. For non-EFI cases, this
apparently was no issue so far, since we can just define our environment
variables conveniently.

efi_loader: hook up in build environment

2016-03-16T01:30:11+00:00

Now that we have all the bits and pieces ready for EFI payload loading
support, hook them up in Makefiles and KConfigs so that we can build.
