Subject: [PATCH 0/2] nvmem: Add Sophgo eFuse driver

Sophgo SoCs such as CV1800B contain eFuses used to store
factory-programmed data such as calibration values for the built-in
ethernet PHY.

As for CV1800B, HW automatically loads the eFuse content into CONTENT
base registers which are organized as 32bit values exposed as MMIO.

Currently, add read support for the eFuse. This is a preparation step
for supporting the built-in ethernet phy.

Since the clk support isn't mainlined, so cv1800b DT patches are not
included.
