atmel_nand pmecc on 8k page

[Raphaël Poggi]

Hi,

I'm working on a series of patches, to support 8k nand page in
atmel_nand driver.

Currently, I can detect the nand and handle an oob size of 448. But i
have a problem with the pmecc, when barebox tried to perform pmecc
operation, I get the following message:

PMECC: Timeout to calculate error location.

Example of log:

nand: NAND device: Manufacturer ID: 0x2c, Chip ID: 0x68 (Micron
MT29F32G08ABAAAWP), 4096MiB, page size: 8192, OOB size: 448

I don't know/find why barebox get a timeout...

Someone have an idea ?
