Greg:
Can you take this patch? Since there is no maintainer for drivers/memory/. It still applies fine on top of 5.7-rc1.
Cheers, -Paul

The driver only uses the registers up to offset 0x54. Since the EFUSE registers are in the middle of the NEMC registers, we only request the registers we will use for now - that way the EFUSE driver can probe too.
