We now have EFI support in U-Boot which worked out of the box on all systems that I tried it on so far. Except for the LS2080ARDB. With this patch set I can successfully boot grub2 and Linux from there on such a system - even using PXE.
This patch set depends on the efi-next queue and the efi runtime rename patch. For easy pulling, you can find the fully applied tree here:
https://github.com/agraf/u-boot.git ls2085-efi-support-v7
v3 -> v4:
- Add CONFIG_CMD_FS_GENERIC to defconfig - Move code into generic quiesce weak function - Exit device for real when going to Linux - Only apply DPL if we have something to apply - New: armv8: ls2080a: Declare spin tables as reserved for efi loader - New: efi_loader: Allow boards to implement get_time and reset_system - New: armv8: fsl-layerscape: Add support for efi_loader RTS reset - New: efi_loader: Declare secure memory as reserved - New: efi_loader: Allow bouncing for network
v4 -> v5:
- Drop patches that are in the efi queue already - efi_loader: Allow boards to implement get_time and reset_system - efi_loader: Allow bouncing for network - Remove manual ttbr / tcr copy - Regenerate page tables in EL2, getting us non-secured page tables - Add qspi board - Don't overwrite ethact - Use __efi_runtime tags - Use gd->arch.secure_ram
v5 -> v6:
- Move distro conversion to end of queue - use CONFIG_DISTRO_DEFAULTS - drop patch: "efi_loader: Declare secure memory as reserved"
v6 -> v7:
- Don't call efi_loader functions for SPL code - Add USB boot support
