These patches only add one line each, and each depends on the previous
anyway.  They should be merged into one patch.

[S.H] I thought one patch doing one thing even it's simple. 
I'm fine with the merge if you insist.

Well, it is a matter of opinion.  I don't insist, but I think it would be 
easier for everyone if you did merge these patches.  Each one is very 
short, and they are all very similar.

[S.H] it's also easier for me. :)
I had to separate the three lines to three patches when sending them, I thought
Someone may NAC the merged patch because it added three features.

This needs more explanation.  What sort of image am I supposed to get  
when I build "P5040DS_NAND"?  Where is the PBI?

What is the long-term plan for fixing the problem of the environment  
not being available until after relocation?  With SPL we could use  
CONFIG_NAND_ENV_DST (which has some issues, but they're fixable).

It would also be nice to include instructions for configuring the board  
to boot from NAND in a README (Freescale's user manuals often do not  
make this clear, especially for soft configuration).  Also please  
provide a built-in command (or script in the default environment) to  
soft-boot into NAND (or if it already exists, please document it).

[S.H] there is already a readme for p3041/p5020/p4080 (doc/README.pblimage), 
With the PBL tool, we will get a ramboot image "u-boot.pbl".
and also the PBI, it is shared by P3/P4/P5.

[S.H] this will need export some NAND read APIs (like load ENV stuff from CONFIG_NAND_ENV_DST),
then they can be reused before relocation even not using SPL.
Please suggest.

[S.H] This exist in the above readme.

[S.H] I was told that when doing ramboot, I should not assume the board has a NOR flash, 
for ex. on customer's board, they may only have NAND. So I did not do this.

The question is how is the user to know that something called  
"pblimage" is relevant to booting from NAND on P5040?  Maybe a  
README.corenet_ds (or board/freescale/corenet_ds/README), that points  
to README.pblimage?

You don't even update strings like "P3041/P5020" in README.pblimage to  
include P5040. :-)
Why is P4080 excluded, BTW?  I realize that P4080DS doesn't have NAND,  
but the file talks about chips, not boards.

The full NAND subsystem will not work before relocation.  Your options  
are to either use SPL (note that you'll have no 4K limitation in this  
case, so you can do SPD DDR init), or make the SPL code available in  
non-SPL context somehow.  I think the former would be easier.

I only see hardware switch settings.  Is there no way to soft-boot into  
NAND (similar to using "pixis/qixis altbank" to boot into an alternate  
NOR bank)?  Our e500v2-based boards have been able to do this...

I'm not asking you to assume that, just to provide some helpful  
instructions for people who happen to have both (in addition to the  
hardware switch instructions that are already there).  Actually, these  
instructions (both soft boot and hardware switches) are board-specific  
rather than SoC-specific and should go in a board README instead.  And  
once you know we're talking about a corenet_ds board, you know we have  
NOR.

[S.H] Yes. A README for corenet_ds board will be more useful, 
then a ramboot section points to README.pblimage.

[S.H] Thanks for pointing it out. I will update the README.pblimage in next version.

 Why is P4080 excluded, BTW?  I realize that P4080DS

[S.H] there is no P4080DS_NAND entry in boards.cfg...

[S.H] Thanks. I will assess the effort base on my case.

[S.H] we do have these soft-boot instructions for corenet_ds board.
And yes, they should go in README of corenet_ds board, 
but seems we don't have such a README.

Yes, I said I realize that P4080DS (note the DS) doesn't have NAND.   
But P4080 the SoC should support NAND boot on custom boards that have  
NAND, and README.pblimage doesn't appear to be talking about specific  
boards (except for the hardware switch section).
