efi_loader: definition of GetNextVariableName()

2020-03-22T17:38:02+00:00

'vendor' is both an input and an output parameter. So it cannot be
constant.

efi_loader: fix freestanding memmove()

2020-03-22T10:06:23+00:00

For EFI binaries we have to provide an implementation of memmove() in
efi_freestanding.c.

Before this patch the memmove() function was copying in the wrong
direction.

efi_selftest: check length reported by GetNextVariableName()

2020-03-22T10:06:23+00:00

GetNextVariableName should report the length of the variable including the
final 0x0000 in bytes.

Check this in the unit test.

Increase the buffer size for variable names. 40 bytes is too short.

efi_loader: correct reported length in GetNextVariable()

2020-03-22T10:06:23+00:00

The runtime service GetNextVariable() returns the length of the next
variable including the closing 0x0000. This length should be in bytes.

Comparing the output of EDK2 and U-Boot shows that this is currently not
correctly implemented:

EDK2:
OsIndicationsSupported: 46
PlatformLang: 26
PlatformLangCodes: 36

U-Boot:
OsIndicationsSupported: 23
PlatformLang: 13
PlatformLangCodes: 18

Provide correct length in GetNextVariable().

efi_loader: export a couple of protocol related functions

2020-03-17T07:29:52+00:00

This is a preparatory patch.
Those functions will be used in an implementation of UEFI firmware
management protocol as part of my capsule update patch.
