Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from the PowerPC port with all the Open Firmware bits removed and replaced by their EFI counterparts. On the whole, I think I prefer Open Firmware. This code is supposed to be an immutable shim that sits on the EFI system partition, loads /boot/loader.efi from UFS and tells the real loader what disk/partition to look at. It finds the UFS root partition by the somewhat braindead approach of picking the first UFS partition it can find. Better approaches are called for, but this works for now. This shim loader will also be useful for secure boot in the future, which will require some rearchitecture.

Ensure we have a large enough stack for the lua loader Lua has a few places where it allocates a large buffer on the stack. This is normally fine, except there are a few places where there can be multiple frames with this buffer. This can cause a stack overflow on some arm64 SoCs. Fix this by allocating our own stack in loader.efi large enough for these objects. The required size has been found by tracing how the stack pointer changes in a virtual machine and found to be no larger than 50kB. A larger stack is allocated to reduce the likelihood of overflow from future changes. Reviewed by: kevans Approved by: re (kib) Differential Revision: https://reviews.freebsd.org/D16886

Add support to the efi boot1 and loader for 32-bit ARM. This will be used by the future qemu virt support. Differential Revision: https://reviews.freebsd.org/D2238 Reviewed by: emaste

Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from the PowerPC port with all the Open Firmware bits removed and replaced by their EFI counterparts. On the whole, I think I prefer Open Firmware. This code is supposed to be an immutable shim that sits on the EFI system partition, loads /boot/loader.efi from UFS and tells the real loader what disk/partition to look at. It finds the UFS root partition by the somewhat braindead approach of picking the first UFS partition it can find. Better approaches are called for, but this works for now. This shim loader will also be useful for secure boot in the future, which will require some rearchitecture.

Revert "Unify boot1 with loader" change r324646 Back out the unification commit to boot1. There's some issues on the arm and arm64 platforms that need to be addressed with code changes. There's also a discussion on arch@ about the future of boot1.efi vs just using loader.efi that needs to play out. So take a pause on these changes until the arm issues can be fixed and it's clear boot1.efi will survive into FreeBSD 12. OK'd by: Eric@meatspace

Use explicit --output-target to set EFI file format According to objcopy(1) --target is for use where the input and output formats are the same ("no translation"). In practice it does detect the input format in any case, but be explicit that we're specifying the output format as we are translating from ELF to EFI PE format. Sponsored by: The FreeBSD Foundation
