[yocto] bring mipsel support (little endian mode)

Tue Jun 26 23:25:41 PDT 2012

HI ALL:
   Sorry for crossing post, but I'm quite new here, so if I did
something wrong, please point me the right direction. thanks
   I'm using oe-core, and notice that mipsel support(o32, little
endian mode) is missing (current available choose is: qemumips,
qemumips64, qemumips64el).
   So, here I'm trying to bring up qemumipsel support . My first
attempt would just make qemumipsel work,
further would make it running on real board, thus maybe mips4kec,
mips24k, mips74k chips.
   What I achieved here current:
  1) toolchain/basic libs, utilities should works ,only one changes,
see my patch [a]
   for mipsel we also have to filter out -march=mips32, previously we
only handle mips (the big endian?)
   don't have the error message now, but if you request, I can provide.
  2) attempt to  compile kernel to support qemumipsel, unfortunately it fail.
The point here is linux-yocto doesn't support qemumipsel, but merely
support those other three mips arches,
So here is my attempt patch [b], and the fail log [c], complied out
binary still big endian.

   Could my patch [a] be accepted? or should I send with another mail
for better review?
   Is it better to request a ticket in yocto's bugzilla? or just
report here, I'm not quite sure.
