X-Git-Tag: release_tools_1_2_4_1~71
X-Git-Url: https://oss.titaniummirror.com/gitweb/?a=commitdiff_plain;h=8b6973832825337ddfbf63f47b4ebd70b40d2c05;p=tinyos-2.x.git

Updated README's to describe different options when compiling for the CC2420.  Updated the Makefile to include the new CC2420 configurations.  This does away with the need for a separate BaseStationCC2420 since no files need to be overridden.
