Broadcom-s U-Boot https://git.openwrt.org/project/bcm63xx/u-boot/atom?h=master 2019-06-05T16:16:34Z 2019-06-05T16:16:34Z Thierry Reding 2019-04-15T09:32:25Z urn:sha1:f9ec2ec8504aa5d94d5be7f43c743040e549b157 Some devices may restrict access to the PMC to TrustZone software only. Non-TZ software can detect this and use SMC calls to the firmware that runs in the TrustZone to perform accesses to PMC registers. Note that this also fixes reset_cpu() and the enterrcm command on Tegra186 where they were previously trying to access the PMC at a wrong physical address.
