[U-Boot-Users] NAND S3C2410 LN2410SBC

[U-Boot-Users] NAND S3C2410 LN2410SBC

[David Farrell]

Hello to the group, I reviewed the email archive I hope I
don't repeat anything.
 
I have just created (mostly copied) a port to the CyberLab
LN2410SBC board.  I have several questions before 
submitting any patch.
 
What is the status of the NAND code? I have the S3C2410 
reporting my chip but I have 2040 or 2048 bad blocks.  I'll
work through it, but I don't want to repeat what someone else
has aleady done.
 
I have reviewed the thread on the arm920t subdirectory 
structure, I'll follow this for s3c2410x.
 
Why are there flash drivers in the board directories?
Is this general enough to be a driver?  Should CMD_xxx
or CONFIG_ xxx defines be used at this level?
 
ps: There is a problem with the memsetup.S code of the 
smdk2410 the sub r0, r0, r1 should be sub r2, r0,  r1 to
copy the table correctly.
 
David.

Dear David,

Working for those of us who bothered to report.

See the mailing list archive ;-)

Where would you put board-specific optimized drivers if not into  the
board directories?

No. But if you like you can use the CFI driver as well.

Can you please be abit more specific?

Best regards,

Hi David.

I'm back from vacations, and I'll try to take a look at the NAND
code.

Please be a little patient...
