Subject: [PATCH v2 9/9] nds32: Fix the allmodconfig build. To make sure CONFIG_CPU_LITTLE_ENDIAN is default y
Date: Fri, 20 Apr 2018 21:31:15 +0800	[thread overview]
Message-ID: <186daa632c13751fc68bc31c52d3230846966a6a.1524229040.git.greentime@andestech.com> (raw)

In-Reply-To: <cover.1524229035.git.greentime@andestech.com>

This way we can build kernel with CONFIG_CPU_LITTLE_ENDIAN=y. Build allmodconfig
and allnoconfig are available too. It also fix the endian mismatch issue because
AFLAGS and LDFLAGS is not passed correctly.
