Subject: xtensa: define CONFIG_CPU_{BIG,LITTLE}_ENDIAN
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4611bf7eb52599cb7549eed10f1ab609cbcdfa4b;p=deliverable%2Flinux.git

xtensa: define CONFIG_CPU_{BIG,LITTLE}_ENDIAN

Query compiler for the CPU endianness and add corresponding definition
to KBUILD_CPPFLAGS. This allows using 'native-endian' property in DTS.
