Subject: efi_loader: use correct type for AllocatePages, AllocatePool
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=49d225e7bf3a26adfe6093978c04e454c82bd955;p=u-boot.git

efi_loader: use correct type for AllocatePages, AllocatePool

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.
