[U-Boot] [PATCH 2/2] arm: i.MX6UL: add Armadeus Systems OPOS6UL SoM and OPOS6ULDev carrier board

Sébastien Szymanski sebastien.szymanski at armadeus.com
Tue Mar 7 13:33:25 UTC 2017


OPOS6UL is an i.MX6UL based SoM with 256MB RAM, 4GB eMMC and an ethernet
phy. OPOS6ULDev is carrier board for the OPOS6UL.
