[U-Boot] Should UEFI be disabled on ARM11 boards by default?

[Heinrich Schuchardt]

Dear maintainers,

"Pull request for UEFI sub-system for efi-2020-01-rc4" disables the UEFI
sub-system for all boards except ARMv8, ARMv7, ARM11. This is necessary
as UEFI requires support for unaligned access. For ARM11 a function is
provided to switch unaligned access support on.

Tom suggested to disable UEFI by default on ARM11 to reduce the size of
the U-Boot binary. This would concern the following boards:

evb-ast2500_defconfig
flea3_defconfig
integratorcp_cm1136_defconfig
mx31pdk_defconfig
mx35pdk_defconfig
rpi_0_w_defconfig
rpi_defconfig
woodburn_defconfig
woodburn_sd_defconfig

At least the Raspberry boards should have no problem with UEFI enabled.

Do you see a necessity to use EFI_LOADER=n as default for any of the
boards in the list above?

Best regards

Heinrich
