The main strategies were: - eliminate hardcoded base addresses; devices use offsets and a BSP defined base address. - separate functionality into different files (e.g. reboot from inch.c to reboot.c) which can be overridden by a 'derived' BSP. - separate initialization code into separate files (e.g. PCI bridge detection/initialization was separated from the more generic PCI access routines), also to make it easier for 'derived' BSPs to substitute their own initialization code. There are also a couple of enhancements and fixes: - IRQ handling code now has a hook for attaching a VME bridge. - OpenPIC is now explicitely initialized (polarities, senses). Eliminated the implicit assumption on the presence of an ISA PIC. - UART and console driver now supports more than 1 port. The current maximum of 2 can easily be extended by enlarging a table (it would even be easier if the ISR API was not broken by design). - fixed polled_io.c so it correctly supports console on COM2 - fixed TLB invalidation code (start.S). - exception handler prints a stack backtrace. - added BSP_pciFindDevice() to scan the pci bus for a particular vendor/device/instance.

before RTEMS is built.
SUPPORT
Information on third-party support for RTEMS.
