-
-The load address for BCM963xx is 0x80010000, not 0xf8001000 as in the current
-sources. I think this is just a typo, so this patch fixes it (tested on 96345).

-
-The ISR ended up in an endless loop because the TX ISR never got used or masked.
-This patch basically makes the TX ISR mask the the TX interrupt when it
-encounters it, because it doesn't even use the TX interrupt.

-Subject: [PATCH] bcm96345: correct some 6345 specific stuff
-
-This fixes some problems with the 6345 support and adds a macro for CPU
-identification that is easier on the eyes. The first thing it does is to not
-initialize MPI on the 6345 as it does not have PCI. The second thing it does is
-to use a static value for the CPU frequency of the 6345 chip to provide an
-accurate timer.
