Subject: [U-Boot] [PATCH 1/6] MIPS: kconfig: add options for endianess select
Date: Sun, 26 Oct 2014 14:37:51 +0100	[thread overview]
Message-ID: <1414330676-22547-2-git-send-email-daniel.schwierzeck@gmail.com> (raw)
In-Reply-To: <1414330676-22547-1-git-send-email-daniel.schwierzeck@gmail.com>

Add new Kconfig option to let the user select the targets
endianess. Each target have to select SUPPORTS_BIG_ENDIAN
and/or SUPPORTS_LITTLE_ENDIAN to indicate which endianess
is supported.
