Subject: [U-Boot] [PATCH] armv7: LS1021a: enable i-cache in start.S
Date: Wed, 14 Sep 2016 11:36:14 +0800	[thread overview]
Message-ID: <1473824174-6137-1-git-send-email-xiaoliang.yang@nxp.com> (raw)

Delete CONFIG_SKIP_LOWLEVEL_INIT define in ls1021atwr.h and
ls1021aqds.h can let it run cpu_init_cp15 to enable i-cache. First
stage of u-boot can run faster after that. There is a description
about skip lowlevel init in board/freescale/ls1021atwr/README.
