Changeset 653 for trunk/softs/tsar_boot/README.txt

Message:

Introducing a RAMDISK driver in the preloader.

When using RAMDISK, execute the make command with the flags
SOCLIB=1 and RAMDISK=1. The RDK_PADDR_BASE variable must
also be set on the conf/<platform>/defs_platform.h

These modifications are backward compatibles. Therefore,
when no using RAMDISK, none modifications applied on the
platform configuration file.
