[U-Boot] [PATCH] driver: net: fsl-mc: Update fsl_mc_ldpaa_exit() path
by Yogesh Gaur 14 Apr '17

14 Apr '17

Earlier when MC is loaded but DPL is not deployed results in FDT fix-up code execution hang. For this case now print message on console and returns success instead of return -ENODEV. This update allows to continue fdt fixup execution.

[U-Boot] [PATCH 1/2] imx-common: Enable ACTLR.SMP bit for i.MX cortex-a7 platforms
by Peng Fan 14 Apr '17

14 Apr '17

According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit is set to 1 before the caches and MMU are enabled, or any cache and TLB maintenance operations are performed". ROM sets this bit in normal boot flow, but when in serial download mode, it is not set. Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms, including mx7d, mx6ul/ull and mx7ulp. When cache not enabled in U-Boot, we also need enable the SMP bit. because kernel does not set this bit, if this bit not enabled, kernel works as cache disabled.
