In 6789e84 we update u-boot-spl.lds for OMAP to ensure we include
adapter information, as we use i2c during SPL. However, the regex used
also means we included commands that may have been built. On omap5_uevm
this leads to a failure as we include the command from the do_tca642x
command, and fail to link. The fix is to restrict our regex to only the
i2c list parts.

Conflicts:
arch/arm/cpu/arm926ejs/mxs/Makefile
board/compulab/cm_t35/Makefile
board/corscience/tricorder/Makefile
board/ppcag/bg0900/Makefile
drivers/bootcount/Makefile
include/configs/omap4_common.h
include/configs/pdnb3.h
Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:
board/compulab/common/Makefile
board/udoo/Makefile
include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.
include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.
Note: 'git show' will also list two files just because
they are new:
include/configs/am335x_igep0033.h
include/configs/omap3_igep00x0.h

We don't need to provide Linux copatibility any more.
This commit deletes include/linux/config.h

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.

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).

Note1:
In arch/arm/cpu/arm926ejs/spear/Makefile
START := start.o
was changed
extra-$(CONFIG_SPL_BUILD) := start.o
because spear/start.o is only used for SPL.
Note2:
START := start.o
was missing from arch/arm/cpu/arm926ejs/mxs/Makefile.
This commit simply adds
extra-$(CONFIG_SPL_BUILD) := start.o

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.
