Nothing wrong that I could see.  I just need to test it first.

The arch/ppc had a bit different partition table.
Something like this:
mtd0: 00180000 00040000 "kernel"
mtd1: 00200000 00040000 "root"
mtd2: 03bc0000 00040000 "user"
mtd3: 00080000 00040000 "env"
mtd4: 00040000 00040000 "u-boot"

Thanks,
Valentine.

Well, arch/ppc calculates the mtd2 dynamically and doesn't create
a separate partition for kozio.

I've based this on how it's currently done for the Sequoia, too.

That dynamic size calculation depends on the flash size.
The board I use has a 64MB NOR flash (I'm not aware of other Taishan 
boards having chips of different size). So AFAIU if such board exists, 
we'll need a cuboot flash-size fixup.

Thanks,
Valentine.

All Taishan boards have 64MB flash (2x32MB). Denx was doing the size  
calculation
to dynamically allocate mtd2 based on the size of mtd0+mtd1 if I recall  
right.

This is actually the code:
arch/ppc/platforms/4xx/taishan.c:static int taishan_setup_flash(void)
{
taishan_nor_parts[2].size = __res.bi_flashsize -
		RW_PART0_SZ - RW_PART1_SZ - RW_PART3_SZ - RW_PART4_SZ;

Thanks,
Valentine.

Please remove the kozio partition from this list. It's not used/supported 
anymore.

Thanks.

And please extend the "user" partition accordingly.

Sorry, forgot to note that this version removes the "kozio" and extends  
the "user" partition accordingly, as Stefan asked.

It won't apply anymore, but the fixups are trivial.  I can do that if
Stefan acks the changes.
