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>

/*

* The purpose of this code is to signal the operational status of a
|
|
* target which usually boots over the network; while running in
|
|
* U-Boot, a status LED is blinking. As soon as a valid BOOTP reply
|
|
* message has been received, the LED is turned off. The Linux
|
|
* kernel, once it is running, will start blinking the LED again,
|
|
* with another frequency.
