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
Do you recall why this is Heinrich?
