efi_loader: update SetVariable attribute check

2023-03-13T12:56:14Z

UEFI specification v2.10 says that EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS is deprecated and EFI_UNSUPPORTED should be returned in SetVariable variable service. Current implementation returns EFI_INVALID_PARAMETER, let's fix the return value. Together with above change, this commit also updates the SetVariable attribute check to be aligned with the EDK2 reference implementation.

efi_loader: set CapsuleMax from CONFIG_EFI_CAPSULE_MAX

2023-02-19T20:15:15Z

Adds CONFIG_EFI_CAPSULE_MAX to configure the max index value used in EFI capsule reports. Prior to this change is the hard coded value was 65535 which would exceed available storage for variables. Now the default value is 15 which should work fine with most systems. Signed-off-by: Etienne Carriere

efi_loader: Measure the loaded DTB

2023-02-19T20:15:15Z

Measures the DTB passed to the EFI application upon new boolean config switch CONFIG_EFI_TCG2_PROTOCOL_MEASURE_DTB. For platforms where the content of the DTB passed to the OS can change across reboots, there is not point measuring it hence the config switch to allow platform to not embed this feature.

lmb: Treat a region which is a subset as equal

2023-02-12T16:54:18Z

In various cases logical memory blocks are coalesced; As a result doing a strict check whether memory blocks are the same doesn't necessarily work as a previous addition of a given block might have been merged into a bigger block. Fix this by considering a block is already registered if it's a pure subset of one of the existing blocks. Signed-off-by: Sjoerd Simons

trace: Detect an infinite loop

If something is wrong with a board's timer function such that it calls functions not marked with notrace, U-Boot will hang. Detect this, print a message and disable the trace. Signed-off-by: Simon Glass

trace: Correct the relocation handover with buffer overflow

2023-02-11T17:22:35Z

When the early trace buffer overflows it leaves a gap in the trace buffer between where the actual data finished and where it would have finished if there were enough buffer space. This results in corrupted output. Adjust the logic to resolve this and add a message when the buffer overflows. Signed-off-by: Simon Glass
