[U-Boot] [PATCH v2] apalis_imx6: increase phy autoneg timeout

[Igor Opaniuk]

From: Igor Opaniuk <igor.opaniuk at toradex.com>

Default value (4000ms) of PHY_ANEG_TIMEOUT for Micrel KSZ9031 contoller
isn't sufficient to finish auto-negotiation, which sometimes leads to
timeout errors:

Apalis iMX6 # dhcp
FEC Waiting for PHY auto negotiation to complete......... TIMEOUT !

Increase the auto-negotiation time-out to 15000ms.

Signed-off-by: Igor Opaniuk <igor.opaniuk at toradex.com>

v2:
- Based on empirical results from Philippe Schenker, increased timeout
  value to 15s, just to be on the safe side
