Porting to a NXP K6x series chip

[george at n3ysa.org]

I've got a FRDM-K64F and would like to get RTEMS running on it for a personal project. It has the standard ARM interrupt controller. One complication is that the SRAM is divided into two banks of 128K as the banks are connected to different buses in the MCU, and causes hard faults if an unaligned access crosses the boundary.

Looking at the existing code, anything specific too the K6x would go in libcpu, and anything specific to board (such as clock setup/debug uart) would appear to go in libsp? 

Thanks,
George
