[ARM]

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
	- add various addresses, boot script, custom C/C++ flags and SD card definition,
	- not sure BoardSetup is included at the best place though,
	- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.
