If u-boot is the boot loader of your board (the stuff running on it
--before-- we see this:
loaded at: 00400000 005153B4
board data at: 00513130 00513334
relocated to: 00405090 00405294
zimage at: 00405A85 00512099
avail ram: 00516000 08000000
Linux/PPC load: rw console=ttyS0 root=/dev/nfs ip=on
Uncompressing Linux...done)
Then I would say NO
If u-boot is this exact stuff (the files in arch/ppc/boot/simple/...
misc-embedded.c for example)
then, yes, this is somehow better.
But (tell me if I'm wrong) this is not really Linux code, and this
should be done by Linux.
What I think should be good also is the platform files
(arch/ppc/platforms/....) for this is the place where all the board
dependant stuff stays.
Maybe I'm completely mistaken.
Feel free to tell me (and explain please !)
Have fun.
