[U-Boot] [PATCH] nand/denali: Adding Denali NAND driver support

[Chin Liang See <clsee@altera.com>]

Hi Rik,

This patch is for U-Boot only.
You might wanna find the kernel patch at
http://rocketboards.org/gitweb/?p=linux-socfpga.git;a=commit;h=23b95d8c25d34afadc82325313f25e72d76c5cef

While for your issue, its quite strange.
Currently, we are using 512 byte sector protected with 8 bit ECC.
With this configuration, we will need around 58 bytes at OOB.
This is to accommodate 2 bytes bad block market +  42 bytes data + 14
bytes ECC.

Wonder you are using different configuration?
Thanks and have a nice day!

Chin Liang
