This patch adds parameter support for the 'reset' command to specify the reboot mode (cold vs. warm).
Checking these parameters is implemented in the DM implementation.

Ouch, I just saw the extra printf might have to be removed in a v2...
Anyway, except for that, I don't think it's platform or driver specific. It's just a way to make the cmd 'reset' take arguments that map to enum sysreset_t.
There is a problem in that other platforms without UCLASS_SYSRESET don't handle these arguments, but I thought UCLASS_SYSRESET would be the future, and the rest would be "legacy"?
