We are evaluating the mpc8241/8245 on the floating point unit. For they

You have to initialize memory controller to certain
addresses BEFORE any use of BATs, ioremap etc.
For example
-BR1/OR1 for BCSR
-BR5/OR5 for ATM
-IMMR
all of them anywhere above 0xf000.
So You can use these addresses with or without MMU
at same address. ( phys = virtual !!!)

Hi!
Yet another PCMCIA question :-)
We need for a project a second 100MBit interface, so our soloution will be to
use a PCMCIA card. Does there exists an actual compatibility list which cards
works, which not? I only found a list from 2000 or 2001.
Please help :-)
Thx in advance

I don't have 8241/8245 experience, but I do have 8260 experience (also uses
the 603e core). Floating point (FPU) works well under linux.
Using floating point in the kernel is severely frowned on, however, because
it takes time, both for the calculations and for additional FPU register

First, you have to learn how to use GDB to deal with the symbol table
of a dynamically loaded module. Second, did you ever try

In the Redhat 7.0 linux, I was able to enable/disable the serial console

However in the case of the 440 Linux the serial console is enabled already.

That is actually not a serial console, it is a serial login. (It's a small
distinction but an important one)
I am not very sure if this is off topic.

You should change the line

This space (after __FUNCTION__) will do the trick.
