Summary
=======

This README is about U-Boot support for TI's ARM 926EJS based family of SoCs.
These SOCs are used for cameras, video security and surveillance, DVR's, etc.
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
an OMAP part number are very similar to the DaVinci series of SOC's
Additionally, some family members contain a TI DSP and/or graphics
co processors along with a host of other peripherals.

Currently the following boards are supported:

* TI DaVinci DM644x EVM

* TI DaVinci DM646x EVM

* TI DaVinci DM355 EVM

* TI DaVinci DM365 EVM

* TI DA830 EVM

* DM355 based Leopard board

* DM644x based schmoogie board

* DM644x based sffsdr board

* DM644x based sonata board

Bootloaders
===============

The DaVinci SOC's use 2 bootloaders. The low level initialization
is done by a UBL(user boot loader). The UBL is written to a NAND/NOR/SPI flash
by a programmer. During initial bootup, the ROM Bootloader reads the UBL
from a storage device and loads it into the IRAM. The UBL then loads the U-Boot
into the RAM.
The programmers and UBL are always released as part of any standard TI
software release associated with an SOC.
