[U-Boot] onenand_ipl : need to cpu/arm_cortexa8/start.S

[U-Boot] onenand_ipl : need to cpu/arm_cortexa8/start.S

[HeungJun Kim]

Dear all,
The cpu/arm_cortexa8/start.S dosen't have the code about onenand_ipl.
But, If the new ARM CortexA8 specific code is addad and the new code needs
to be
used the onenand_ipl features, it's hard to be implemented this new code.

So, I wonder whether it's right or not to be changed like this in the
start.S :

1. at the reset vector -> just jump reset code.
2. execute cpu_init_crit() like not onenand_ipl code.
3. setup stack area.
4. jump start_oneboot.

I wish to listen any advice of yours.
Thanks to read.


Best Regards,
riverful

For people who don't know your CPU (system? flash architecture? way to 
boot?) and have no real idea what's "the onenand_ipl features" might 
be: Do you kindly like to give some additional details about the 
problem, what onenand_ipl features are, why it is hard to add the new 
code etc.

Getting a better idea about the problem would help to get a solution 
for this ;) If you have, some example code might help, too.

Many thanks and best regards

Dirk
