I have comments interspersed. Most are on formatting and should be
considered as just those I managed to spot.
the rtems-testing git repo has a directory of merge-helpers and
a check script which (I hope) helps you identify some of these
in more detail.

This is rough from an English viewpoint. How about:
Currently, a bootloader is not used. For test and debug purposes, TI's
HalCoGen generated
application is used to set up the board and then the RTEMS application
image is loaded
using OpenOCD to internal EEC SRAM or external DRAM. The following
features are
not implemented in the BSP:
+ Initial complex CPU and peripheral initialization
+ Self-test
Can you be more specific about what that first bullet covers?
Is the generated setup code available? What's the license on it?

Not needed any longer. Hopefully these aren't in any other BSPs. I
thought they
were all stripped out.

Please use clockdrv_shell.h and look at the clock driver for erc32 or
jmr3904 for
examples. This will eliminate a lot of the code you have here. It is
just duplicated
boilerplate.
That lets you define a few macros and the driver just falls out.

Does spprintk have the right output? I question the newline/CR expansion.

This doesn't match the expected style. The rules are here:
http://www.rtems.org/wiki/index.php/Coding_Conventions
But Sebastian Huber has also posted uncrustify setup which is
linked to from there and is
http://www.rtems.org/wiki/images/d/db/Rtems.uncrustify
As a minimum, the If should be "if (" and the return should be on a separate
line.
The code in the if..SCIRD is not lined up.
