-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
-
-* TI DA850 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.
-
-Environment Variables
-=====================
-
-The DA850 EVM allows the user to specify the maximum cpu clock allowed by the
-silicon, in Hz, via an environment variable "maxcpuclk".
-
-The maximum clock rate allowed depends on the silicon populated on the EVM.
-Please make sure you understand the restrictions placed on this clock in the
-device specific datasheet before setting up this variable. This information is
-passed to the Linux kernel using the ATAG_REVISION atag.
-
-If "maxcpuclk" is not defined, the configuration CONFIG_DA850_EVM_MAX_CPU_CLK
-is used to obtain this information.
