efi_loader: don't use EFI_LOADER_DATA internally

2022-12-02T18:17:24+00:00

EFI_LOADER_DATA/CODE is reserved for EFI applications.
Memory allocated by U-Boot for internal usage should be
EFI_BOOT_SERVICES_DATA or _CODE or EFI_RUNTIME_SERVICES_DATA or _CODE.

efi_loader: AllocateAddress requires page address

2022-11-06T09:50:04+00:00

AllocatePages() can be called with Type=AllocateAddress. Such a call can
only succeed if *Memory points to the address of an unallocated page range.

A call with *Memory being an address that is not page aligned must not
succeed. The UEFI specification requires returning EFI_OUT_OF_RESOURCES
if the requested pages cannot be allocated.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \

efi_loader: Fix loaded image alignment

2021-10-21T01:46:04+00:00

We are ignoring the alignment communicated via the PE/COFF header.
Starting 5.10 the Linux kernel will loudly complain about it. For more
details look at [1] (in linux kernel).

So add a function that can allocate aligned EFI memory and use it for our
relocated loaded image.

efi_loader: use correct type for AllocatePages, AllocatePool

2021-08-17T15:24:08+00:00

Use enum efi_memory_type and enum_allocate_type in the definitions of the
efi_allocate_pages(), efi_allocate_pool().

In the external UEFI API leave the type as int as the UEFI specification
explicitely requires that enums use a 32bit type.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

efi_loader: remove outdated TODO in efi_memory.c

2021-01-13T01:38:01+00:00

In efi_mem_sort() adjacent memory regions of same type are coalesced.
Remove the remark "Merging of adjacent free regions is missing".
