Hi Tom,
BLK is currently a dependency for EFI_LOADER as shown in the snippet from
lib/efi_loader/Kconfig below. Perhaps the question is why EFI_LOADER requires a
block device? If I remove this depends on BLK line, then I can enable EFI and
successfully simulate the EFI hello world on my test design.
config EFI_LOADER
bool "Support running UEFI applications"
depends on OF_LIBFDT && ( \
ARM && (SYS_CPU = arm1136 || \
SYS_CPU = arm1176 || \
SYS_CPU = armv7 || \
SYS_CPU = armv8) || \
X86 || RISCV || SANDBOX)
# We need EFI_STUB_64BIT to be set on x86_64 with EFI_STUB
depends on !EFI_STUB || !X86_64 || EFI_STUB_64BIT
# We need EFI_STUB_32BIT to be set on x86_32 with EFI_STUB
depends on !EFI_STUB || !X86 || X86_64 || EFI_STUB_32BIT
depends on BLK
depends on !EFI_APP
default y if !ARM || SYS_CPU = armv7 || SYS_CPU = armv8
Thanks.

And why are you trying to enable BLK without any block devices?
