2010-11-28ARM: imx: Get the silicon version from the IIM moduleDinh Nguyen
Instead of reading the silicon version from ROM, we should read the SREV register from the IIM. Freescale has dropped all support for MX51 REV1.0, only MX51 REV 2.0 and 3.0 are valid. Signed-off-by: Dinh Nguyen <Dinh.Nguyen@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2009-11-23ARM: MX3: fix CPU revision number detectionDaniel Mack
The macro mx31_revision() used to take the global variable system_rev to determine the CPU revision number. However, this number is expected to be set by the bootloader and is usually zero (at least on my MX31 based boards here). More than that, it is usually taken to identify the board's revision, not the CPU's. Fix that by reading the the CPU's SREV register instead. Right now, mx31_read_cpu_rev() is called from mx31_clocks_init() which is admittedly not a good place for it. However, we need to enable the IIM clock first, and the clock code also has conditional code that depends on mx31_revision() returning the right thing.
