This is the chip that's in the Buffalo NAS as well as the TS-7800 SBC.
Do the current stable gcc / binutils / linux-headers sources include all of the necessary patches for this chip yet?
I'm just planning on updating the gentoo-wiki with some instructions on how to build a cross-compiler for the ts7800 board, like the 72xx OABI EABI howto's from a while ago.
Cheers, Chris
