[U-Boot] [PATCH v5 21/28] drivers/fsl-mc: Autoload AOIP image from NOR flash

York Sun yorksun at freescale.com
Sat Mar 21 03:28:25 CET 2015


From: "J. German Rivera" <German.Rivera at freescale.com>

Load AIOP image from NOR flash into DDR so that the MC firmware
the MC fw can start it at boot time.

[York Sun: This is a debug commit. Will drop once AIOP is loaded by Linux]
