- EFI_MEMORY_ATTRIBUTES_TABLE_GUID,
- EFI_TCG2_FINAL_EVENTS_TABLE_GUID.

The cycle register is not guaranteed to count at constant frequency.
If it is counting at all depends on the state the performance monitoring
unit. Use the time register to measure time.

If the EFI graphics pixel format is PixelBltOnly, we cannot write directly
to the frame buffer. We need the shadow frame buffer which we copy via
the BitBlt operation to the hardware.
If the pixel format is PixelBltOnly and allocation of the shadow frame
buffer fails, we must raise an error to signal that the EFI GOP protocol
is not usable.

The EFI_CONFORMANCE_PROFILES_TABLE_GUID is used for a table of GUIDs for conformance
profiles (cf. UEFI specification 2.10, 4.6.5 EFI_CONFORMANCE_PROFILE_TABLE).
The lsefisystab command is used to display installed EFI configuration tables.
Currently it only shows the GUID but not a short text for the table.
Provide a short text for the EFI_CONFORMANCE_PROFILES_TABLE_GUID.

As of version 2.38 binutils defaults to ISA specification version
2019-12-13. This version of the specification has has separated the
the csr read/write (csrr*/csrw*) instructions and the fence.i from
the I extension and put them into separate Zicsr and Zifencei
extensions.
This implies that we have to adjust the -march flag passed to the
compiler accordingly.

In the context of the implementation of the EFI_LOAD_FILE2_PROTOCOL for
the initial ramdisk it was observed that opening the SNP protocol failed.
https://lists.gnu.org/archive/html/grub-devel/2021-10/msg00020.html
This is due to an incorrect call to CloseProtocol().
The first parameter of CloseProtocol() is the handle, not the interface.
We call OpenProtocol() with ControllerHandle == NULL. Hence we must also
call CloseProtcol() with ControllerHandel == NULL.
Each call of OpenProtocol() for the same network card handle is expected to
return the same interface pointer. If we want to close the protocol which
we opened non-exclusively when searching for a card, we have to do this
before opening the protocol exclusively.
As there is no guarantee that we successfully open the protocol add checks
in the transmit and receive functions.
