[OpenWrt-Devel] Howto force mips64

[John Crispin]

Hi Martin,

you win the medal as contributor of the day ... i have been fighting
with octeon on and off for almost a month. i just dumped my own series
of patches which tried to fix up uclibc and simple did what you wrote
in the mail and i have a functional image for octeon :)

i just tested this on an esr-lite which seems to work without your
kernel patches. what board are you running on ?

	John
