Add board specific EEPROM handling module,
read the serial number from the EEPROM and pass it to Linux.

* Fix strange linker warning: ".bss section overlaps previous sections"
by changing the type of the eeprom_layout static global variable to int
(probably this is a compiler bug).
Probably it is now. Did you inspect the linke rmap?
u-boot.map shows the bss section aligning perfectly with the start of
rel.dyn.
The difference between the original "working" version and the version
with the warning
was an additional byte added by uchar eeprom_layout to the size of
libcm_t35.o.
This shouldn't be a problem because the bss section is followed by an
ALIGN(4), but
we decided to try changing eeprom_layout to an int and the problem went
away.
When we tried to define 4 uchars the problem reappeared.
This suggests that this might be a compiler bug.
There's been some discussion about this in the following threads:
http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/114646
http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/90723
and we're not aware of any fix to the issue.
Which prompted me to test --no-check-sections with CS 2009q1. Adding it
to LDFLAGS_u-boot does reduce the annoyance from errors to a warning,
but there is no way to completely make it disappear.
Amicalement,
