From 97597b962529fef9c6976bab57f25ef5ce5e7383 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Tue, 19 Mar 2013 17:00:31 +0530 Subject: [PATCH] ARM: OMAP2+: hwmod: Don't call _init_mpu_rt_base if no sysc OMAP hwmod layer does the reset of the IPs in early code so that we have SOC in sane state. To do the soft-reset, it needs to ioremap() the IP address space to be able to write to sysconfig registers. But there are few hwmod which doesn't have sysconfig registers and hence no need to ioremap() them in early init code. Prevent calling the _init_mpu_rt_base() conditional based on sysc availability.
