This changeset adds write support to meson efuse driver. The first patch just changes the way the nvmem data are allocated w/o any functional changes. The second patches actually adds write support.
The memory being an OTP, it is safer if it remains read-only by default, which is why I also submitted this DT patch [0].
If a user knows what he is doing, it should be easy to remove the read-only property from the board DT. This can be done in u-boot, before starting linux:
> fdt rm /efuse read-only
Tested on the gxl libretech-cc
