bootable GENERAL kernel for the 3 machines.
This is done by integrating the ARM7500 in a better way. In various places
the IOMD ID is checked and action is taken at runtime compared to
compiletime.
The small piece of assembler that is changed now uses the flag
`arm7500_ioc_found' that is set up by iomd.c at startup. When this chip
isnt found at startup it will skip reading the ARM7500 extended IRQ
registers and wont clear them either.
The next step will be getting the mode-definition files to the bootloader.
Currently they are compiled in.
- Most changes are comment cleanups.
_ iomd.h is no longer an exported header.
- Added intr.h for MI interrupt definitions.
- Added definitions for ARM8 cpu.
- Added bus dma support.
