Hi Masahiro,
For ARMv8, the secure firmware (ex. ARM Trusted Firmware BL31) is often implemented, making U-Boot a non-secure world boot loader.
The secure firmware generally includes PSCI. The power management operations, including System Reset, are supposed to be handled by PSCI. In this case, U-Boot should not touch the system reset directly. Instead, U-Boot should call PSCI service to reset the system.
In order to implement this, arm-smccc code is needed. The code has been copied from Linux. (1/2)
2/2 implements a generic sysreset driver based on the PSCI specification.
I'm just wondering if it would be possible to:
Provide the exact Linux files (with SHA1) from main line
On top of this patch add u-boot adjustments
Add u-boot specific support for PSCI
In this way we would have exact info about the source of porting (or was it ported exactly from v4.11-rc6 tag?)
I am OK with this.
I will wait for a little more comments before sending v2.
Thanks!
