Replace #define types with typedefs.
Rename all typedefs to have a _t extension.
Add #defines to automatically convert old FreeRTOS specific types to their new names (with the _t).
Update the Cortex-A9 port to include asserts if an ISR safe FreeRTOS function is called from an interrupt that has a higher logical priority than configMAX_SYSCALL_INTERRUPT_PRIORITY (or whatever the CA9 equivalent is called), and also assert if the binary point is not set correctly.
