Hello,

I wrote a SPI Driver for Collie. It's very slow, because it runs at the lowest clock ATM. You can play with different speed using:
/sys/bus/locomo-bus/drivers/locomo-spi/clockmult
/sys/bus/locomo-bus/drivers/locomo-spi/clockbase
I don't know yet what the numbers mean, but I will soon.

Patches can be found at http://www2.informatik.hu-berlin.de/~tkunze/zaurus/patches .
The important ones are:
locomo-r0.patch:
-fixes GPIO direction setting
-implements SPI irq setting
locomo_spi-r0.patch
-the spi driver
mmc_spi-r1.patch
-from LKML with very little changes by me

I will provide a bootstrap-image for testing soon:

Cheers,

Thomas

AFAIK there is no status page for 2.6 on collie. Maybe I should set up one. You can find some pieces of information with google, but much is out of date. There are angstrom-test images at: http://www.angstrom-distribution.org/unstable/images/collie/

The kernel is not ready for end-users yet:

Things that work more or less:
- LCD
- Keys
- Leds
- PCMCIA
- MMC/SD
- Serial Port
- Flash
- Battery/Charging

Things that should work (havent tested):
- Touchscreen
- Irda
- USB Client

Things that doen't work yet:
- Suspend/Resume
- Audio (buzzer + headphone jack)

The SD driver should support at least 4 GB SD-Cards. You have to load the modules locomo-spi and mmc-block to use SD-Cards.
