In int-ll64.h, we always use the following typedefs:

This does not need to match to the compiler's <inttypes.h>.

sparse constantly complains about truncated constant value in efi.h:

This can get quite noisy, preventing real issues to be noticed:

The commit 21b3edfc96 ("efi_loader: check parameters of CreateEvent")
enforces a strict parameter check at CreateEvent(). On the other hand,
UEFI specification version 2.7, section 7.1, says:
The EVT_NOTIFY_WAIT and EVT_NOTIFY_SIGNAL flags are exclusive. If
neither flag is specified, the caller does not require any notification
concerning the event and the NotifyTpl, NotifyFunction, and
NotifyContext parameters are ignored.
So the check should be mitigated so as to comply with the specification.

We currently expose host addresses in the EFI memory map. That can be
bad if we ever want to use sandbox to boot strap a real kernel, because
then the kernel would fetch its memory table from our host virtual address
map. But to make that use case work, we would need to have full control
over the address space the EFI application sees.
So let's expose only U-Boot addresses to the guest until we get to the
point of allocation. EFI's allocation functions are fun - they can take
U-Boot addresses as input values for hints and return host addresses as
allocation results through the same uint64_t * parameter. So we need to
be extra careful on what to pass in when.
With this patch I am successfully able to run the efi selftest suite as
well as grub.efi on aarch64.
