- mpc55xx/misc/flash_support.c: New file.
- Makefile.am: Reflect change above.
- mpc55xx/include/mpc55xx.h: Add definitions for the FLASH interface
and two memory protect interfaces. Add modifications to eliminate
warnings in some of the cache macros.
- mpc55xx/include/regs.h: Add some structure tag names for some
structures that I needed access to. Don't define the ALTCADR for the
MPC5554 - it is reserved and acess casues an exception. Hide the C99
designated initializers when compiling with C++. Add some support for
the EQADC.
- mpc55xx/include/esci.h, mpc55xx/include/watchdog.h: Add C++
protection.
