| |
When building allmodconfig KCONFIG_ALLCONFIG=$(pwd)/arch/arm64/configs/defconfig CONFIG_CPU_BIG_ENDIAN gets enabled. Which tends not to be what most people wants. Another concern that thas come up is that ACPI in't built for an allmodconfig kernel today since that also depends on !CPU_BIG_ENDIAN.
Rework so that we introduce a 'choice' and default the choice to CPU_LITTLE_ENDIAN. That means that when we build an allmodconfig kernel it will default to CPU_LITTLE_ENDIAN that most people tends to want.
