README: davinci: update the documentation for DaVinci

Browse Source 
The DM* family of SOCs is no longer supported. We now support the
omap-l138 lcdk board and Lego EV3 platform. Reflect those changes
in the README.

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.
Note: this document used to be about the entire family of DaVinci SOCs but the
support for the DM* family and DA830 has since been dropped.
This README is about U-Boot support for TI's DA850 SoC. This SOC has an OMAP
part number but is very similar to the DaVinci series.
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
* TI OMAP-L138 LCDK
* DM644x based schmoogie board
* DM644x based sffsdr board
* DM644x based sonata board
* Lego EV3

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.
For DA850 an SPL (secondary program loader, see doc/README.SPL) is provided
to load U-Boot directly from SPI flash. The SPL takes care of the low level
initialization.
Alternative boot method (DA850 EVM only):
For the DA850 EVM an SPL (secondary program loader, see doc/README.SPL)
is provided to load U-Boot directly from SPI flash. In this case, the
SPL does the low level initialization that is otherwise done by the SPL.
To build U-Boot with this SPL, do
make da850evm_config
make u-boot.ais
and program the resulting u-boot.ais file to the SPI flash of the DA850 EVM.
The SPL is built as u-boot.ais for all DA850 defconfigs. The resulting
image file can be programmed to the SPI flash of the DA850 EVM/LCDK.
