Re: [U-Boot] [PATCH v4 1/2] vf610twr: Add default environment in line with other Freescale boards

This adds a default environment which should be able to support both 3.0.15 from Timesys and upcoming 3.11.

Signed-off-by: Otavio Salvador otavio@ossystems.com.br

Changes in v4:

• revert sys text address change (Alison)
• add mem=128M to bootargs/netargs (Andy)

Just curious: why do we need to pass mem=128M?

Changes in v3:

• add dt boot support
• use ttyLP1 as console
• change loadaddr and sys text as iMX6SL
• NOTE: It needs to be boot tested as I don't have the board

Changes in v2:

• fix console for ttymxc1 (Fabio)
