[PATCH V6 0/4] arm64: imx8mp: Read values from M24C32-D write-lockable page on DHCOM i.MX8MP

[Christoph Niedermaier]

The new i.MX8M Plus DHCOM rev.200 is populated with M24C32-D EEPROM
that contains an additional write-lockable page called ID page, which
is populated with a structure containing ethernet MAC addresses, DH
item number and DH serial number.

This patch series prepare the device tree of the DHCOM i.MX8MP for
reading the EEPROM ID page. Add the reading of the content and set the
correspondent environment variable. It also synchronize two serial
number environment variable via callback functions and fixing recursive
calling of them.

To ensure that the environment callback functions work, this patch
series depends on patch [1].
