Nand support

[Philippe12]

Hi I try to add nand support on uboot.

But I have a question in uboot the nand is normally manage by mtd device but in kernel it manage by block.

Which will it be the best work :

• to add under mtd for uboot and change the driver for kernel.
• to add like block device in uboot (that no standard) and don't change the nand driver in kernel.

Allwinner have a block driver ontop of their nand, but normally NAND drivers in the kernel is also MTD.

Yes

Kernel & u-boot MTD drivers is in progress. First kernel version is available mainline. But much help is needed if you are interested.

  * to add like block device in uboot (that no standard) and don't
    change the nand driver in kernel.

The Allwinner block NAND driver is a very odd beast, and is very unlikely to get into mainline Linux or u-boot versions.

It's great I worked on and driver on mtd I can read/write and in integer fast boot for android. But it work in FEL mode. I din't find where I must write in nand the SPL for booting?
