From fd6b9c978dc3447b9b4677d8949ef3ea7f946abc Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sun, 14 Dec 2008 21:26:25 -0300 Subject: V4L/DVB (9895): cx18: Refine the firmware load and firmware startup process Refine the firmware load and firmware startup process. Significant changes are to ensure the SCB and IPC area are correct before starting up the firmware, and letting the CPU firmware start up the APU firmware for us.
