When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commitc8ffd1356d, reversing changes made to2ee6f3a5f7. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>

* Possible future work:
|

* - verify sectors before/after are not erased/written
|
|
* - verify partial writes (e.g. programming only middle of sector)
|
|
* - verify the contents of the erased sector
