Guide to ARMLinux for Developers by Wookey and Paul Webb. Aleph One, April 2001. This book is much more narrowly focused than Lombardo's book. You can read it on-line at www.aleph1.co.uk/armlinux/thebook.html. A second edition, with chapters on porting to a new platform and much more on filing systems and system-generation tools, is due out later this year.
