You need to add a new platform. Basically you can do the same thing as
it's done with the integrator platform. The UART implementation goes to
src/lib/uart/arm, and need to be hooked in
src/kern/arm/kernel_uart-arm.cpp.

Most likely. The PIC implementation goes to src/kern/arm/pic-arm.cpp,
and the timer goes to src/kern/arm/timer-arm.cpp. Other files to look at
are Modules.arm to specify the label to build under and probably
rules.cml to add a new platform. The CPU specific things may also need
adaptions.
