It is a region of some miscellaneous registers, some related to reset.

There is not other stuff in this region that to be exposed,
and so we really don't need a real driver.
My suggestion is to perhaps make that more explicit in the proposed
device tree node, by making the reg size "4" and naming it
as per the register name
rstcr: rstcr@1E60000 {
compatible = "syscon";
reg = <0x0 0x1E60000 0x0 0x4>;
};
The intent is really just to expose a single reset register
and use syscon-reboot until PSCI is available.
Thanks,
Stuart
