The first part of the question is simple:

If you count all *.S, *.c and *.h files you get: 474537 LOC.

The second part of the question is more difficult.  What  exactly  do
you  mean? How much manpower went into the PPCBoot / U-Boot projects?
How much it would take to do it again,  with  today's  knowledge  and
experience,  but  without  looking at the code? To get exact the same
state, i. e. support for all the 100+ boards?

The project is about 2.5 years old now. I guess (and this is  a  wild
guess)  that  about 25 man years went into the U-Boot / PPCBoot until
now; to redo it from scratch, I guess you'd need 2...5  man-years  if
you could select at your liking from all the developers who worked on
it; if you cannot do this, I think it would take 5...10 man-years.

A wild guess, as I said.

Best regards,

Wolfgang Denk
