I'm new to the PPC and I have a few questions. I have written a driver
in the past for the X86 family, using i/o ports, but it was kernel 2.0 and
i/o ports are not mmu handled.
I've been looking through the archive and I am slowly growing more
We are using Xilinx with PPC built in.
The PPC has a memory management unit. All of the IP we've added is
mapped to physical addresses.
1. Can I access the memory the peripherasl are mapped to directly within
the driver without going through functions?
if NOT, then Do I use
4. something else?
2. Are there any gotcha's with the ppc 405 that Xilinx uses that I
should know about?
