> According to TRM for i.MX8M Nano and Plus, GPR10 register contains lock
> bit for TZASC_ID_SWAP_BYPASS bit. This bit is required to be set in
> order to avoid AXI bus errors when GPU is enabled on the platform.
> TZASC_ID_SWAP_BYPASS bit is alread set for all imx8m applicable
> derivatives, but is missing a lock settings to be applied.
> Set the TZASC_ID_SWAP_BYPASS_LOCK bit for those derivatives which have
> it implemented.
> Since we're here, provide also names to bits from TRM instead of using
> BIT() macro in the code.
> Fixes: deca6cfbf5d7 ("imx8mn: set BYPASS ID SWAP to avoid AXI bus errors")
