omap-l138 lcdk board and Lego EV3 platform. Reflect those changes
in the README.

This README is about U-Boot support for TI's ARM 926EJS based family of SoCs. Note: this document used to be about the entire family of DaVinci SOCs but the
These SOCs are used for cameras, video security and surveillance, DVR's, etc. support for the DM* family and DA830 has since been dropped.
DaVinci SOC's comprise of DM644x, DM646x, DM35x and DM36x series of SOC's
Additionally there are some SOCs meant for the audio market which though have This README is about U-Boot support for TI's DA850 SoC. This SOC has an OMAP
