[U-Boot] [PATCH] arm: omap: Fix 'get_device_type()' for OMAP34XX

[Derald D. Woods <woods.technical@gmail.com>]

Fixes 00bbe96ebabb (arm: omap: Unify get_device_type() function) where
the control status register value is embedded in a structure somewhere
in SRAM. This patch allows OMAP3 EVM (TMDSEVM3530) to boot again using
a known global constant and offset for 'readl'.
