This patch allows the endianness of the JFSS2 filesystem to be
specified by mount option 'force_endian=big|little|native'. If
endianness is not specified, it defaults to 'native' endianness
thus retaining the existing behavior.
Some architectures benefit from having a single known endianness
of JFFS2 filesystem (for data, not executables) independent of the
endianness of the processor (ARM processors can be switched to either
endianness at run-time).
We have boards that are shipped with BE jffs2 and BE kernel. We are
now migrating to LE kernel. This mount option helps us in mounting
BE jffs2 on LE kernel.
