efi_loader: do not miss last relocation block

2019-02-16T14:51:14+00:00

If the last block in the relocation table contains only a single
relocation, the current coding ignores it.

Fix the determination of the end of the relocation table.

efi_loader: set entry point in efi_load_pe()

2019-02-16T14:42:20+00:00

Up to now efi_load_pe() returns the entry point or NULL in case of an
error. This does not allow to return correct error codes from LoadImage().

Let efi_load_pe() return a status code and fill in the entry point in the
corresponding field of the image object.

efi_loader: refactor efi_setup_loaded_image()

2018-09-23T19:55:31+00:00

Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL
inside efi_setup_loaded_image(). Do not use local variables.

Currently we expect the loaded image handle to point to the loaded image
protocol. Additionally we have appended private fields to the protocol.

With the patch the handle points to a loaded image object and the private
fields are added here. This matches how we handle the net and the gop
object.

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.
