[PATCH V2 0/3] nvmem: support post read for U-Boot's "ethaddr"

From: Rafał Miłecki <rafal@xxxxxxxxxx>

This change is required for NVMEM consumers to get expected MAC address
from U-Boot env data variable "ethaddr".

To address some previous concerns:
1. Yes, U-Boot env binding & driver should be converted to NVMEM layout
2. My priority is to get working MAC rather than fancy DT syntax
3. I AM going to convert U-Boot env into layout later
4. This work DOESN'T conflict with layout migration
5. This code WILL stay during / after layout migration

My brain limitations don't allow me to handle everything at once, please
let's review what I already have here.

Rafał Miłecki (3):
dt-bindings: nvmem: u-boot,env: add MAC's #nvmem-cell-cells
nvmem: core: support specifying both: cell raw data & post read
lengths
nvmem: u-boot-env: post-process "ethaddr" env variable
