[U-Boot] [RFC 0/4] MXC: Add NAND support for i.MX31

[Magnus Lilja <lilja.magnus@gmail.com>]

Hi all,

This series adds NAND support for i.MX31 using the mxc_nand that was
added for i.MX27. The same NAND Flash Controller is used in i.MX31.

I've done some limited run-time testing on the Litekit using small
page NAND and it seems to work.

I have embedded a question in patch #2 and #4, this relates to where
the 16 bit SoC specific auto detection code shall be placed.


Once I've received input on the open question I will clean up the series
and do the necessary MAKEALL tests (not done at the moment), add 
signed-off-by and re-submit.



On a separate note, the Linux version of mxc_nand.c is undergoing updates
(don't think the patches have been accepted yet) and unfortunately it's
not just a matter of copying the new version since the uboot version was
converted to use readw(&host->regs->register) instead of 
readw(host->regs + REGISTER). 
But in any case, there may be things to import to u-boot.


Regards, Magnus
