This patch set augments Simon's patch set for efi_loader support in sandbox[1], but follows a different memory allocation scheme.
Instead of keeping U-Boot addresses in the EFI memory map, this patch set makes the EFI memory map contain host virtual addresses. That way most logic "just works" and all EFI interfaces automatically gain sandbox awareness.
We also change the memory map of sandbox to hard code RAM to always live at address 0x80000000. This patch is completely optional.
With this patch set in place, I can successfully run the selftest suite as well as an aarch64 grub.efi binary. X86_64 grub.efi doesn't work because that one requires inl instructions to work.

v1 -> v2:
- only compile efi_add_known_memory if efi_loader is enabled - clarify address vs pointer in fs_read patch - include mapmem.h
v2 -> v3:
- removed: efi_loader: Pass address to fs_read() - new: fs: Convert fs_read/write to take buffer instead of address - new: efi_loader: Introduce ms abi vararg helpers - new: sandbox: Enable 1:1 map - new: distro: Move to compiler based target architecture determination - new: efi_loader: Move to compiler based target architecture determination - new: sandbox: Allow to execute from RAM - new: sandbox: Fix setjmp/longjmp
Alexander Graf (13): efi_loader: Use compiler constants for image loader efi_loader: Use map_sysmem() in bootefi command efi.h: Do not use config options efi_loader: Allow SMBIOS tables in highmem sandbox: Map host memory for efi_loader efi_loader: Disable miniapps on sandbox fs: Convert fs_read/write to take buffer instead of address efi_loader: Introduce ms abi vararg helpers sandbox: Enable 1:1 map distro: Move to compiler based target architecture determination efi_loader: Move to compiler based target architecture determination sandbox: Allow to execute from RAM sandbox: Fix setjmp/longjmp
Heinrich Schuchardt (1): efi_loader: efi_allocate_pages is too restrictive
Simon Glass (3): efi: sandbox: Add distroboot support efi: sandbox: Add relocation constants efi: sandbox: Enable EFI loader for sandbox
