Author: raj Date: Tue Oct 14 10:11:14 2008 New Revision: 183878 URL: http://svn.freebsd.org/changeset/base/183878 Log: Initial support of loader(8) for ARM machines running U-Boot. This uses the common U-Boot support lib (sys/boot/uboot, already used on FreeBSD/powerpc), and assumes the underlying firmware has the modern API for stand-alone apps enabled in the config (CONFIG_API). Only netbooting is supported at the moment.
