efi_loader: check map_key in ExitBootServices

2018-07-25T12:59:44+00:00

The UEFI spec requires that the memory map key is checked in
ExitBootServices().

efi_loader: Expose U-Boot addresses in memory map for sandbox

2018-07-25T12:57:44+00:00

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.

efi: sandbox: Adjust memory usage for sandbox

2018-07-25T12:57:44+00:00

With sandbox the U-Boot code is not mapped into the sandbox memory range
so does not need to be excluded when allocating EFI memory. Update the EFI
memory init code to take account of that.

efi_loader: efi_allocate_pages is too restrictive

2018-07-25T12:57:43+00:00

When running on the sandbox the stack is not necessarily at a higher memory
address than the highest free memory.

There is no reason why the checking of the highest memory address should be
more restrictive for EFI_ALLOCATE_ANY_PAGES than for
EFI_ALLOCATE_MAX_ADDRESS.

efi_loader: efi_mem_carve_out should return s64

2018-06-03T13:27:21+00:00

efi_mem_carve_out() is used to remove memory pages from a mapping.
As the number of pages to be removed is a 64bit type the return type
should be 64bit too.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.
