Subject: ARM: mxs: Setup stack in JTAG mode
In case the MX23/MX28 is switched into JTAG mode via the BootMode select
switches, the BootROM bypasses the CPU core registers initialization.
This in turn means that the Stack Pointer (SP) register is not set as
it is in every other mode of operation, but instead is only zeroed out.
To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure
the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out.
Note that in case the SP is already configured, we must preserve that exact
SP value and must not modify it. This is important since in every other mode
but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads
U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to
continue it's operation after returned from SPL and the system would crash.
Finally, add the JTAG mode switch identifier, so it's not recognised as
Unknown mode.

Subject: dra7xx_evm: Enabled UART-boot mode and add dra7xx_evm_uart3 build
UART booting is supported on this SoC, but via UART3 rather than UART1.
Because of this we must change the board to use UART3 for all console
access (only one UART is exposed on this board and a slight HW mod is
required to switch UARTs).

Subject: ARM: OMAP5: DDR3: Change io settings
The change from 0x64656465 to 0x64646464 is to remove the weak pull
enabled on DQS, nDQS lines. This pulls the differential signals in the
same direction which is not intended. So disabling the weak pulls improves
signal integrity.
On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by
the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's
VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being
supplied a VREF! This was clearly a mistake. The second change improves the robustness of
the interface and was specifically seen to cure corruption observed at high temperatures
on some boards.
With the above two changes better memory stability was observed with extended
temperature ranges around 100C.
