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 |
