Replace the shim-specific fork with the upstream version, specifically the most recent release. Some adjustment to shim's code are necessary to adapt to this change. Signed-off-by: Andrea Bolognani <abologna@redhat.com>
shim is a standalone EFI application so it shouldn't be necessary to look at the glibc headers when building it, and in fact attempting to do so results in a build failure. Signed-off-by: Andrea Bolognani <abologna@redhat.com>
We could theoretically set GNU_EFI_USE_REALLOCATEPOOL_ABI=0 to keep using the legacy ABI, but since gnu-efi uses the modern ABI internally and we call into its build systemd directly, doing that messes things up. Switching to the new ABI is just a matter of changing the order of arguments. Signed-off-by: Andrea Bolognani <abologna@redhat.com>

Upstream gnu-efi doesn't implement the AsciiSPrint() function. Drop its only user. This reverts commit 77a2922 Signed-off-by: Andrea Bolognani <abologna@redhat.com>
Add what is needed to build on riscv64. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> This is an update to rhboot#420 which brings it in alignment with the current upstream. Signed-off-by: Brian 'redbeard' Harrington <redbeard@dead-city.org> (cherry picked from commit 5031a99)
@davidlt and @xypron pointed out prior changed to binutils 2.42 which added support for RISC-V EFI objects. This reflects the upstream preference to avoid adding additional architectures which are emitting flat binary files via `objcopy` (i.e. `-O binary` architectures). (cherry picked from commit 9f9813b)

This is part of an attempt to bring riscv64 support into shim.
See #420 and #641 for previous discussion, as well as #777 which is a prerequisite of this PR.
Using this branch I was able to successfully build shim on both x86_64 and riscv64, and I was able to use the resulting binaries to boot Fedora 42 cloud images for both architectures, replacing the stock ones.
