Subject: [PATCH 05/11] efi.h: Add allocation types for
|
|
boottime->allocate_pages()
|
|
|
|
commit bb05e4ba452ada7966fbced4e829aa029f546445 upstream.
|
|
|
|
Add the allocation types detailed in section 6.2 - "AllocatePages()"
|
|
of the UEFI 2.3 specification. These definitions will be used by the
|
|
x86 EFI boot stub which needs to allocate memory during boot.
