Hi Heinrich,
I've run into a problem with mainline U-Boot. Debian unstable (distro kernel) fails to boot after commit b02a707152, "efi_loader: enable UEFI variables at runtime". Kernel boots fine before that commit. Boot log is attached. Looks like it is failing in a workqueue that is calling runtime services; but I haven't dug in yet.
I'm not doing anything exotic with this build. Mainline U-Boot, mainline TFA, and booting the kernel with an up-to-date dtb.

Hello Grant,
this is the patch you are needing:
https://lists.denx.de/pipermail/u-boot/2020-July/421193.html [PATCH 1/1] efi_loader: efi_current_var after SetVirtualAddressMap
Got it. Working now. Thanks! g.
There is also an issue to current Linux kernels fixed by:
efi/efivars: Expose RT service availability via efivars abstraction
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=f8881...
Without the patch if SetVariable() is not available, you cannot access GetVariable() in Linux.
Best regards
Heinrich
