efi_loader: don't use memmove() in efi_var_mem_del()

2020-07-22T10:32:41+00:00

efi_var_mem_del() is in __efi_runtime because it would be needed for a
runtime implementation of SetVariable(). memmove() is not in __efi_runtime.
So we should not use it in efi_var_mem_del().

efi_loader: optional pointer for ConvertPointer

2020-07-11T21:14:17+00:00

If the EFI_OPTIONAL_PTR is set in DebugDisposition, a NULL pointer does not
constitute an invalid parameter.

efi_loader: export efi_convert_pointer()

2020-07-11T21:14:17+00:00

We need ConvertPointer() to adjust pointers when implementing  runtime
services within U-Boot.

After ExitBootServices() gd is not available anymore. So we should not use
EFI_ENTRY() and EFI_EXIT().

efi_loader: round the memory area in efi_add_memory_map()

2020-05-17T19:59:53+00:00

Virtually all callers of this function do the rounding on their own.
Some do it right, some don't. Instead of doing this in each caller,
do the rounding in efi_add_memory_map(). Change the size parameter
to bytes instead of pages and remove aligning and size calculation in
all callers.

There is no more need to make the original efi_add_memory_map() (which
takes pages as size) available outside the module. Thus rename it to
efi_add_memory_map_pg() and make it static to prevent further misuse
outside the module.

efi_loader: implement EFI_RT_PROPERTIES_TABLE

2020-02-26T18:32:09+00:00

UEFI spec 2.8 errata A replaces the RuntimeServicesSupported variable
defined in UEFI spec 2.8 by the configuration table
EFI_RT_PROPERTIES_TABLE. So let's follow suit.
