Makefile: Move SHELL setup to config.mk
make never uses the SHELL variable from the environment. Instead, it
uses /bin/sh, or the value assigned to the SHELL variable by the Makefile. This
makes the export of the SHELL variable useless for sub-makes (but still useful
for the environment of recipes). However, we want all makes to use the same
shell.
This patch fixes this issue by moving the SHELL variable setup and export to the
top config.mk, so that all Makefile-s including it use the same shell.
Since BASH is used by default, this makes it possible to use things
like 'echo -e ...' in sub-makes, which would otherwise fail e.g. with /bin/sh

powerpc/lib: fix unsafe register handling in wait_ticks
If watchdog is enabled, the arch/powerpc/lib/ticks.S::wait_ticks() function
calls the function specified by the WATCHDOG_RESET macro.
The wait_ticks function depends on the registers r0, r6 and r7 being
preserved however that is not guaranteed, e.g. if the reset function is a
C function this will probably overwrite r0 and cause an endless loop.
The following patch changes to using r14+r15 instead of r6+r7 (to resemble
what would have been generated by a C compiler) and saves all necessary
registers on the stack.
The patch has been tested on a custom MPC5125 based machine using the 512x

For production systems it is better to use script images since
they are protected by checksums and carry valuable information

passed to env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.
