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.
