Just wondering - is there a case where using volatile for UCC parameter RAM for
example will not work, or is the use of I/O accessors everywhere an attempt to
be portable to other architectures?
I'm asking because I really want to know ;)

Just wondering how I can get kgdb to show me the contents of MURAM on the QE?

to other devices on the
same bus in the meantime, this device may be confused and fail the first
transaction.
Maybe the chip select should be disabled until the device entry is initialized
with full knowledge of its configuration. Not sure of the right solution.

If we use open firmware, then alow_flags handles active-low
chipselects, which is the same as SPI_CS_HIGH. This patch fixes the
double negative.

Anton,
thanks to your device table matching support patch I can use open firmware

Hang on - I missed your most recent patches to spi_mpc8xxx

Anton - thanks for the offline correction.
SPI_CS_HIGH means that the device interprets high as active.
The alow flag means there is an inverter somewhere.
My mistake - patch retracted.

I can't think of a reason not to do this. The data register has no
effect except when the pin

Hello Anton,
Is m25p_probe now valid with dev.platform_data == NULL, for of platforms?
Then shouldn't you have the following change as well, near the end of
