env exists is a way to test (in hush) if an environment variable
exists. A workaround existed using printenv but this new command
doesn't require all the stdout/stderr redirection to prevent
printing information to the screen.
Example:
$ set testexists 1
$ env exists testexists && echo "yes"
yes
$ env exists testexists || echo "no"
$ set testexists
$ env exists testexists && echo "yes"
$ env exists testexists || echo "no"
no

We expect boards_by_* function to return the 7th filed, 'Target',
not the 6th field, 'Board name'.
So the function names, boards_by_* are a little misleading,
and should be renamed to targets_by_*.

Commit 27af930e changed the boards.cfg format
and it changed boards_by_field() function incorrectly.
For tegra cpus it returned Board Name field,
not Target field.
This commit restores the behavior prior to 27af930e in the right way.

pxelinux and syslinux differ in their handling of absolute paths in menu
files. A pxelinux path is aways prepended with the bootfile path while
syslinux allows for absolute paths. u-boot was always treating a leading
/ as an absolute path breaking some pxelinux setups. Fix this by adding
a flag to distinguish pxelinux vs. syslinux behavior.

Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:
CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down
All functions are weak or ifdef'ed so they can still be overriden by any
platform.

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.
