TZC400 on LS1046A

Hi,

I would like to seek some clarification regarding the process of enabling TZC400 on LS1046ARDB. Specifically, I want to know if the file "TZC400.c" found in the "drivers/arm/tzc/tzc400.c" directory of the Arm Trusted Firmware repository is adequate for configuring TZC400 on LS1046A or there are any other code files that require attention for this configuration.

For reference I have attached TZC400.C file please do check.

Awaiting response.

Thanks,
Faizan

You also need drivers/nxp/tzc/plat_tzc400.c, please refer to drivers/nxp/tzc/tzc.mk and drivers/nxp/drivers.mk, TZASC_NEEDED has already been enabled on LS1046A processors.
