ARM: mx6: define CONFIG_ARM_ERRATA_742230 The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is claimed for Cortex-A9 (r1p0..r2p2). Though i.MX6 uses a newer revision than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be fixed by applying the workaround for this errata. So for safety, let's define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> 2013-04-16 04:58:47 +00:00			`#define CONFIG_ARM_ERRATA_742230`

mx6: soc: Add the required LDO ramp up delay When changing LDO voltages we need to wait for the required amount of time for the voltage to settle. Also, as the timer is still not available when arch_cpu_init() is called, we need to call it later at board_postclk_init() phase.
