Hi Fred,

do not worry, I could find where the problem is located. I started from
the IMX51 BSP, changing code to adapt for the u-boot top of tree, and
then I applied all changes you sent in your patchset. So I could check
step by step where I had to look.

I do not find any issue in the cpu/mx51/clock.c and in the clock
definitions, that you rearranged after the first review, so in this file
everything seems ok ;)

Definitely I checked with the debugger that the problem arises in the
first initialization of the clock registers in lowlevel_init.S (after
the init_clock label).
I replaced the file with the one I found in the BSP and the board runs
now flawlessly.

I have already removed the flashHeader.S, adding a new image format to
support the i.MX51 processor and its DCD table.

I have opened another issue, too. I have seen that the name "babbage" is
quite disappeared and on the Freescale's website this board is named now
"mx51evk". I know you have already changed the name of the board, but I
think the name "babbage" can confuse. Better should be to rename the
board with the name we find in the official documentation. I know you
already did this job, I can only volunteer myself to do that...

What do you think if I take over the job and I will resend all patches
to the ML ? In this way I can easier integrate my changes, if you agree.
Should be ok for you ?

Best regards,
Stefano Babic
