ENGR00131932-1 MX51, MX53, sdma: Upgrade SDMA scripts to v1.1.0 version
Upgrade sdma mx51 script to v1.1
http://compass.freescale.net/go/220269616
Upgrade sdma mx53 script to v1.1
http://compass.freescale.net/go/211002731
These new scripts support ssi dual fifo.
Pan Qihong-B30266 provide the usage:
-----------
mcu_2_ssiapp and ssiapp_2_mcu are supporting
SSI tx/rx residing on peripheral DMA region.
mcu_2_ssish and ssish_2_mcu are supporting
SSI tx/rx residing on shared peripheral DMA region.
With all these 4 scripts, will support all the 3 SSIs.
