Re: 8260 io and caches

From what I can see, the uart driver in the current linux source is written

for the 860, with no mods for the 8260.

Oh, there are some mods, but I did start with the 8xx code :-).

....  The 8260 has some different bits
in the RFCR/TFCR parameter RAM fields.  There is a GBL bit (bit 2) that
enables cache snooping.

Oooops.  Sorry about that.  I was playing with caches (and not) and
I guess I didn't get everything checked in properly.  Make sure you
also make the same cache changes to the SCC Ethernet.

Don't consider this software ready to run.  I have more to check
in and I am still making lots of changes.

.....  Of course, you probably want to add a SMC_GBL
#define to do this properly.

It was supposed to be there...........
