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.

The UEFI specification defines that the EFI_BOOT_SERVICES.Exit(() service may return
EFI_SUCCESS or EFI_INVALID_PARAMETER. So it cannot be __attribute__((noreturn)).

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.
