ARM: OMAP3+: Detect reset type
Certain modules are not affected by means of a warm reset and need not be configured again. Adding an API to detect the reset reason warm/cold. This will be used to skip the module configurations that are retained across a warm reset. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com>
