Adds code to detect AM43xx HS EVMS - the string in the
I2C EEPROM for HS EVMs differs from GP EVMs. Adds code to
for evm detection, regardless of whether the evm is for
GP or HS parts, and updates board init to use that.
Modifies findfdt command to pick up am437x-gp-evm.dtb for
the HS EVMs also, as the boards are similar except for
some security specific changes around power supply and
enclosure protection.

Now that we have a generic TI eeprom logic which can be reused across
platforms, reuse the same.

AM43xx Industrial Development Kit is a new board
based on AM437x line of SoCs. Targetted at Industrial
Automation applications, it comes with EtherCAT, motor
control and other goodies.
Thanks to James Doublesin for all the help.

* Boot failures have been discovered due to a combination of routing issues and
non optimal ddr3 timings in the EMIF
* Since ddr3 timings are different after significant board layout changes
different timings are required for alpha, beta and production boards.

AM43xx Starter Kit is a new board based on
AM437x line of SoCs. Being a low-cost EVM and
small size EVM are intended to provide an entry
level development platform on a full fledged
Hardware System.

Updating the Multiplier and Dividers value for all DPLLs.
Safest OPP is read from DEV ATTRIBUTE register. Accoring to the value
returned the MPU DPLL is locked.
At different OPPs follwoing are the MPU locked frequencies.
OPP50 300MHz
OPP100 600MHz
OPP120 720MHz
OPPTB 800MHz
OPPNT 1000MHz
According to the latest DM following is the OPP table dependencies:
VDD_CORE VDD_MPU
OPP50 OPP50
OPP50 OPP100
OPP100 OPP50
OPP100 OPP100
OPP100 OPP120
So at different OPPs of MPU it is safest to lock CORE at OPP_NOM.
Following are the DPLL locking frequencies at OPP NOM:
Core locks at 1000MHz
Per locks at 960MHz
LPDDR2 locks at 266MHz
DDR3 locks at 400MHz
Touching AM33xx files also to get DPLL values specific to board but no
functionality difference.
