Subject: m32r: fix endianness constraints
The m32r Kconfig provides both CPU_BIG_ENDIAN and CPU_LITTLE_ENDIAN
configuration options. As they are user-selectable and independent, this
allows invalid configurations:
- All m32r defconfigs build a big endian kernel, but CPU_BIG_ENDIAN is
not set, causing compiler warnings like:
include/linux/byteorder/big_endian.h:7:2: warning: #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN [-Wcpp]
#warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN
^
- Since commit 5bdfca6435b82944 ("m32r: define CPU_BIG_ENDIAN"),
building an allmodconfig or allyesconfig enables both
CONFIG_CPU_BIG_ENDIAN and CONFIG_CPU_LITTLE_ENDIAN.
While this did get rid of the warning above, both options are
obviously mutually exclusive.
Fix this by making only CPU_LITTLE_ENDIAN configurable by the user, as
before, and by making sure exactly one of CPU_BIG_ENDIAN and
CPU_LITTLE_ENDIAN is always enabled.
