efi_loader: ResetSystem() should not hang

2020-08-24T14:37:53+00:00

If ResetSystem() is not implemented at runtime, it should return instead
of hanging in an endless loop. This allows the operating system to reset
the system by other means as Linux does. It also matches what EDK II
suggests in comments for functions ResetShutdown() and ResetWarm() in
OvmfPkg/Library/ResetSystemLib/ResetSystemLib.c.

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.
