GoboLinux for ARM CPUs
The GoboLinux port for ARM CPUs has been happening with a focus on the armv5te, having the XScale as optimization target.
The entire process of development has been done with the Bootstrap tool, described some sections below, which consists on a menu based interface to select and compile packages.
All of this is free software and you're heavily encouraged to try it, enhance it and join us with the development of GoboLinux for the embedded. ...

HeyRick! Arm Personal Site
The documents here relate to the low-power high-performance ARM processors used in PDAs, mobile phones, laser printers, Gameboy Advance, and of course the RISC OS computer range (formerly made by Acorn Computers, Cambridge, UK). A lot of the detail relates to programming the ARM within the RISC OS environment, but it should also serve as a general resource for those programming the ARM under any system
