Hi Albert.
Hi,
I'm ready to pick up your Gamecube and Wii patch sets for merging.
You seem to have 4 distinct patch sets. What order do they need to be
applied in, and what kernel version are they based on?
The patches were based on 2.6.32-rc8.
The apply order

Great work Albert!
Thanks!
Cheers,

Add a set of entries to the fixmap table to allow usage of known
reserved virtual address space by early debug code.
The address space reserved is the top 128K of the 32-bit address
space. This allows, if required, the use of a BAT to do the mappings.

This is v4 of the early debugging using usbgecko patch.
It tries to implement the ideas suggested by Benjamin Herrenschmidt
regarding the use of a set of fixmap entries to provide safe
virtual address space for an early mapping.

powerpc: reserve fixmap entries for early
Add support for using the USB Gecko adapter as an early debugging
console on the Nintendo GameCube and Wii video game consoles.
The USB Gecko is a 3rd party memory card interface adapter that provides
a EXI (External Interface) to USB serial converter.
