Currently u-boot maps whole of 1G RAM but there reserved memory ranges on QCS404 which are reserved for TrustZone, various firmware components etc. Any access to these reserved memory ranges causes a bus hang issue. So disable mapping for reserved memory ranges in u-boot. Signed-off-by: Sumit Garg <sumit.garg@linaro.org>
