that seems possible : the main differences at u-boot level are the
eSDHC (3 on the RiOT vs 2 on the MarS) and the SPI flash which is
populated in the MarSBoard (and used for boot when the RiOT boots on
the eMMC). I'll check how to factorize the code.

Comparing this patch agains the earlier one for the  RiOTboard, it
turns out that the differences between these two boards are really
minimal.

Would it not make sense to combine all the common code?  Actually I
think you should be able to use all common code with just two
different target names.

Best regards,

Wolfgang Denk

[U-Boot] [PATCH 2/2] MarSBoard: add new board

2014-03-26 Thread Eric Bénard 
this board is produced by Embest/Element 14 and is based on i.MX6 Dual
The following features are tested :
- UART2 (console)
- eMMC
- uSDCard
- Ethernet
- USB Host (through 2 ports hub)
- HDMI output
- I2C 1/2
- SPI NOR Flash

Boot on SPI NOR and through USB loader are tested.

For more informations on this board :
