efi_loader: Use compiler constants for image loader

2018-07-25T12:57:43+00:00

The EFI image loader tries to determine which target architecture we're
working with to only load PE binaries that match.

So far this has worked based on CONFIG defines, because the target CPU
was always indicated by a config define. With sandbox however, this is
not longer true as all sandbox targets only encompass a single CONFIG
option and so we need to use compiler defines to determine the CPU
architecture.

riscv: Add support for HI20 PE relocations

2018-06-14T08:52:14+00:00

The PE standard allows for HI20/LOW12 relocations. Within the efi_loader
target we always know that our relocation target is 4k aligned, so we
don't need to worry about the LOW12 part.

This patch adds support for the respective relocations. With this and a
few grub patches I have cooking in parallel I'm able to run grub on RISC-V.

efi_loader: correctly apply relocations from the .reloc section

2018-06-03T13:27:20+00:00

Instead of difference between preferred and actual image base, the
actual base is added to the fields specified in the .reloc section.

Use ImageBase from PE optional header to compute the delta,
exit early if the image is loaded at the preferred address.

efi_loader: Use EFI_CACHELINE_SIZE in the image loader too

2018-05-29T06:43:12+00:00

We were using our EFI_CACHELINE_SIZE define only in the runtime service
code, but left the image loader to use plain CONFIG_SYS_CACHELINE_SIZE.

This patch moves EFI_CACHELINE_SIZE into efi_loader.h and converts
the image loader to use it.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

efi_loader: Check machine type in the image header

2018-04-06T07:28:01+00:00

Check FileHeader.Machine to make sure the EFI executable image is built
for the same architecture. For example, 32-bit U-Boot on x86 will print
an error message instead of loading an x86_64 image and crashing.

efi_loader: new functions to print loaded image information

2018-04-05T13:23:55+00:00

Introduce functions to print information about loaded images.

If we want to analyze an exception in an EFI image we need the offset
between the PC and the start of the loaded image.

With efi_print_image_info() we can print the necessary information for a
single image, e.g.

UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi'

efi_print_image_infos() provides output for all loaded images.
