Hi,
I'm currently adding support for a GE board based on the Freescale
P2020. This board has a cascaded interrupt controller and GPIO which
should be compatible with drivers currently provided for the MPC8641D
based boards that are already in the kernel.
At the moment the drivers (in gef_gpio.c and gef_pic.c) are in the
"arch/powerpc/platforms/86xx" folder. As the p2020 is not 86xx, I guess
I should move these drivers to a more central location. I'm currently
not sure where would be best to move them to, I see
"arch/powerpc/sysdev" and "arch/powerpc/platforms" as potential
locations, where would be the most suitable?
Martyn

I would suggest arch/powerpc/platforms as its board specific code and =
not chip specific. However others gripe at me about that from time to =
time.
