Platform Resource Usage
The SA11x0 OS timer is used as a polled timer to provide timeout support for XModem file transfers.
Rebuilding RedBoot
These shell variables provide the platform-specific information needed for building RedBoot according to the
procedure described in
Chapter 3 :
export TARGET=brutus
export ARCH_DIR=arm
export PLATFORM_DIR=sa11x0/brutus
