Move QEMU's CONFIG_EFI_GRUB_ARM32_WORKAROUND=n from defconfig to
Kconfig.

Why? Are we about to move this to be a short list of "default y if
..."
instead? Otherwise no, this is the level of detail that should be
in a
defconfig I think and not Kconfig.
Hello Tom,
yes, in the long run I want to turn this into "default y if". But I first need to a list of all ARCH_* which have a cache which is not controlled via CP15.
Isn't the bigger problem / list "needs to support old / buggy GRUB" ?
There are no operating systems distributing 2021 U-Boot with 2018 GRUB.
Then we should remove default y there after v2020.10 I think, and get the distro folks to ack/review that. I don't think there's any cases of "SoC doesn't use CP15 for cache" and "SoC uses GRUB".
