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:

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

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.

In efi_mem_sort() adjacent memory regions of same type are coalesced.

efi_loader: use CONFIG_STACK_SIZE in the UEFI sub-system

2020-08-01T09:58:23+00:00

The Kconfig symbol CONFIG_STACK_SIZE is used both by ARM and Microblaze
with the same meaning. Move it to menu 'General setup' so that we can use
it for all architectures.

Use the value of CONFIG_STACK_SIZE instead of a hard coded 16 MiB value for
reserving memory in the UEFI sub-system.
