The following patches add the base support for the Nintendo GameCube
and Wii video game consoles on the powerpc arch.
For each video game console, the following is included:
- a device tree source
- bootwrapper support
- udbg console option
- early udbg console option
- interrupt controller support
- platform support
The Nintendo Wii patches also include support for:
- recognition of the broadway processor
- workarounds to enable the use of the second discontiguous RAM block
With these patches both video game consoles can fully boot up to the
root filesystem mount phase.

Add support for using the USB Gecko adapter as a bootwrapper 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.

The Nintendo GameCube and Wii video game consoles do not have PCI hardware.
Avoid wasting their scarce memory by not including PCI support into the

Add support for using the USB Gecko adapter via the udbg facility 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.

bootwrapper.
dtbImage.wii is a wrapped image that contains a flat device tree,
an entry point compatible with the Homebrew Channel and BootMii,
and an optional initrd.

This patch extends the cputable entry of the 750CL to also match
the 750CL-based "Broadway" cpu found on the Nintendo Wii.
As of this patch, the following "Broadway" design revision levels have
been seen in the wild:
- DD1.2 (87102)
- DD2.0 (87200)

Add support for the dual interrupt controller included in the "Hollywood"
chipset of the Nintendo Wii video game console.
This interrupt controller serves both the Broadway processor (as a cascade)
and the Starlet processor, and is used to manage interrupts for the
non-classic hardware.

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.

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.

RFC v2 -> v2
- use Vp=0 instead of Vp=1 for the early BAT mapping.
Suggestion by Segher Boessenkool.
Note that the patch was acked-by without the single change from
RFC v2 to v2.

The top portion of MEM2 (the second 64MB memory block) in the Nintendo
Wii video game console is used by the firmware running on the Starlet
processor.
Add code to calculate the portion of MEM2 safely useable by the
Broadway processor. When running under the 'mini' firmware this is
easily determined from an in-memory header. Otherwise, a safe default
is used.

From: Albert Herranz @ 2009-12-12 16:31 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Albert Herranz
The Nintendo Wii video game console has two discontiguous RAM regions:
- MEM1: 24MB @ 0x00000000
- MEM2: 64MB @ 0x10000000
Unfortunately, the kernel currently does not support discontiguous RAM
memory regions on 32-bit PowerPC platforms.
This patch adds a series of workarounds to allow the use of the second
memory region (MEM2) as RAM by the kernel.
Basically, a single range of memory from the beginning of MEM1 to the
end of MEM2 is reported to the kernel, and a memory reservation is
created for the hole between MEM1 and MEM2.
With this patch the system is able to use all the available RAM and not
just ~27% of it.
This will no longer be needed when proper discontig memory support
for 32-bit PowerPC is added to the kernel.

Add a flag to let a platform ioremap memory regions marked as reserved.
This flag will be used later by the Nintendo Wii support code to allow
ioremapping the I/O region sitting between MEM1 and MEM2 and marked
as reserved RAM in the patch "wii: use both mem1 and mem2 as ram".
This will no longer be needed when proper discontig memory support
for 32-bit PowerPC is added to the kernel.
