Over the last few months, off and on, I've tried to get a Freescale eval =
board, designated the P1020wlan, up.

I've gotten a few hints from another person who has a 'slightly' =
different eval board, there have been several 'points' which were not =
clear, and for which I hardwired some hacks to overcome.

As it is, I don't see many people using the ppc other than Apple =
variants, G4/G3, etc.

I've gotten the kernel up, mounted a NFS root system, etc. but at the =
last point I left things, I was looking at the code that assigns the =
interrupt line from the Atheros PCI-Express card to however that is =
handled 'logically' to 'real' in the kernel.

One of the hacks I made was getting the freeBSD kernel 'pci' code to go =
beyond seen the processors 'pci' config registers, as there are 2 pcie =
interfaces, and then 'seeing' the atheros cards.

It appears that the atheros cards are 'INTA', but that doesn't tell me =
what interrupt 'number' is the 'logical' numbering scheme, although I =
can sort of determine which 'pic' interrupt is being used from the CPU =
manual.

If this sounds a bit foggy, I've not looked at this in a month as I've =
been on vacation, and now have other 'priorities' to attend to.

I would however like to get back to this port at some point.

Thanks,
John Clark.

PS  Adrian --
You have a wiki on a mips port to a TPline wr-1043 device=85 what would =
be required for the tplink-wr842nd=85 tnx
