In testing my merge of Korat PPC440EPx board support into PPC4xx branch "for-1.3.2", I found problem with the "DIAG RUN CACHE" command. The same problem occurs in the latest for-1.3.2 code for sequoia. Here is a copy of the console output showing what happens:

Thanks for reporting. I'll try to take a look at it in the next days. But I have no problems at all, if you provide a patch to fix it. ;)

OK, I found the problem and fixed in the for-1.3.2 branch:

commit 8092791c5d959e89f9bc4ed0ff880c3509da743f Author: Stefan Roese sr@denx.de Date: Sat Dec 22 12:18:26 2007 +0100

ppc4xx: Fix problem in 44x cache POST routine

As repoted by Larry Johnson, running "diag run cache" caused a crash
in U-Boot. This problem was introduced by a patch that removed the
TLB entry for the cache test after the test has completed. Since this
TLB was only setup once, a 2nd attempt to run this cache test
failed with a crash. Now this TLB entry is created every time the
routine is called.

This fixes the problem on Korat as well. Thanks!
