Hi all,
In the linux-mips cvs big endian operation of the au1550 is not
selectable. Is there a reason for this?
what would I need to do to get big endian support?
The chip does run big endian, as I have yamon running on it here.
And a previously the linux-mips kernel allowed this.
The kernel will compile big end but I get an oops as the kernel
starts up
Thanks
JP
