Russ Butler c730c63f1d Update K64F memory map for for larger static data
The KSDK2 update restricts static data to the first 64K of RAM.
This breaks some applications which require more than 64K of
static data.  This patch moves the static data sections
(bss and data) into the second ram region which is 192K.
