More on my SPI driver questions

More on my SPI driver questions

[clark]

	Hello Again,

	I should have been a little more informative in my previous post. I am
using a custom board with a MPC850ZTxxBT. Right now I am running ppcboot
and kernel 2.2.13 . My board does use SCC2 as its Ethernet connection. So I
do assume I need the IIC/SPI microcode patch.

	So to restate my original questions. I was wondering if anbody has a
working SPI driver yet that gets along with SCC2 Ethernet? Is there any
known side effects IIC/SPI microcode patch?

Many thanks in advanced

	Conn Clark

Adding some lines you should be able to use my code.

The I2C/SPI host commands (Init Rx/Tx params, close RxBD) are not
supported when using the patch. Therefore you have to take care of some
register values yourself. There is a Motorola document that explains more
details. I can send you this.
