I just finished a port for LPC32xx controllers complete with VFP context saving.
This port is based on the ARM7_LPC23xx code with IRQ handling from the
NXP CDL Library. The VFP support was ported from the ARM_Cortex-R4 port.
The systick is generated using the millisecond timer.
Tasks that wish to use the FPU must call vPortTaskUsesFPU() first.
