Subject: [PATCH v3] ARM: imx: Get rid of only i.MX8M SMCCC arch call
Date: Wed, 13 Apr 2022 11:31:30 +0200 (CEST)	[thread overview]

> This is the only place where i.MX8M code does SMCCC call, remove it.
> The output has little value as it prints some part of commit ID, and
> worse, if there is no SMC handler installed, the code outright hangs
> or crashes the system.
> By removing this one instance of SMCCC call, U-Boot no longer depends
> on SMC handlers and can boot without hanging in any case. If there is
> a need to dump this commit ID, use CMD_SMC instead and do 'smc' call
> from U-Boot shell or scripts instead of hard-coding SMCCC dependency
> into architecture code. This particular code can be replaced by:
>  => smc 0xc2000003 0 0 0 0 0 0
