Subject: [PATCH] nvmem: imx-ocotp: Reverse MAC addresses on all i.MX derivates
|
||
|
|
|
||
|
|
Not just i.MX8M, but all i.MX6/7 (and subtypes) need to reverse the
|
||
|
|
MAC address read from fuses. Exceptions are i.MX6SLL and i.MX7ULP which
|
||
|
|
do not support ethernet at all.
|
||
|
|
|
||
|
|
Fixes: d0221a780cbc ("nvmem: imx-ocotp: add support for post processing")
