Incorrect multiline comment style.
Please check other files for that, too.

I will add my copyright in a couple of files, but I would rather not add it to Makefiles. Below I quote an earlier post on this list (funnily, I wasn't able to get it in sourceforge's archive...), which addresses Copyrights in Makefiles. To me it sounds reasonable, because in my example I really added very little "IP" to it, almost exclusively copy-paste from other Makefiles. What I learned, is one may never delete copyrights from files, ones they are there, that's why I preserved yours - that's how this file was in Samsung's version. But I don't think my Copyright there will serve any good purpose.

Thanks for the credit, but, although IANAL, I think, one does not _have_ to preserve the copyright of the original file when it gets copied to a new one. Otherwise most open-source files would have a veeeery long list of Copyrights:-) Am I right?
Thanks Guennadi
IANAL, but I play one on Groklaw sometimes, much to PJ's chagrin. ;-)
This is a squishy area. It is dependent on what of the original work survives the modification and whether the surviving pieces are copyrightable. It also depends on what country you are contemplating suing in.
http://en.wikipedia.org/wiki/Limitations_and_exceptions_to_copyright
Things that must be done in certain ways are not copyrightable, so Makefiles are pretty marginal to start with IMHO.
http://en.wikipedia.org/wiki/Threshold_of_originality
My opinion is to leave the original copyright notice in there and err on the side of preserving reasonable copyright notices. The lawyers will be happy to tell us that we did it wrong if it ever came to a lawsuit, and I would prefer that they tell us that we had a useless copyright notice in the file rather than tell us that we should have had a notice but didn't...
Best regards, gvb

No, you cannot do that without asking him. Maybe you find his address somewhere?

You mean insert my name in that line? But I haven't had anything to do with this file in 2006:-) This is an old line from Samsung sources. I thought your request above was the same as this one:

this is version 2 of the smdk6400 patch series. I hope, I took care of all comments, apart of these ones:

Sorry, looks like a matter of taste to me. There are also very few lines over 80 characters left, but fixing them would look too awkward...

I _think_ this should work with all NAND chips. Otherwise we might have to introduce a configuration variable.

SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl driver for it too. The board can also boot from the NOR flash, but due to hardware limitations it can only address 64KiB on it, which is not enough for U-Boot. Ported from u-boot-1.1.6 version by Samsung.

Sorry, looks like a matter of taste to me. There are also very few lines over 80 characters left, but fixing them would look too awkward...
This is not a matter of taste. Please fix these, too!
Best regards,

Version 3: now all lines over 80 characters are gone. And a couple more checkpatch warnings with them.

I _think_ this should work with all NAND chips. Otherwise we might have to introduce a configuration variable.

I don't follow the logic here -- you're discarding a number of good blocks equal to the offset? That might make sense if we were starting at block zero, and defining the offset as not including any bad blocks before the image -- but the first block we read is at the start of the image, not the start of flash.

It's a large-page device. And, as far as I understand the datasheet, to read data at arbitrary offset in a page, you first have to issue a READ PAGE (READ0) for _the_ _whole_ page, then you can use RANDOM DATA READ to read arbitrary data within this page. Whereas, the driver attempts to use READ0 to read the bad-block marker directly, which doesn't work with this chip. At least this is my understanding.

Acually, it was to improve readability:-) First, this way you can easier grep. Secondly, when I see an assignment to a _variable_, I expect, that this variable's value can indeed _vary_.

It replaces a short lower-case name with a longer all-caps name that forces line breaks. I'm fine with adding "const".

The READ0 command says, "Starting from the initial column address and going to the end of the page, read the data by repeatedly pulsing RE# at the maximum tRC rate (see Figure 14)." That looks normal... have you tried it?
IIUC, the "complete page of data" refers to the transfer from the NAND storage to the chip's page buffer, not to the transfer from the buffer to the CPU.

Notice: USB on s3c6400 currently works _only_ with switched off MMU. One could try to enable the MMU, but map addresses 1-to-1, and disable data cache, then it should work too and we could still profit from instruction cache.

Can we start to avoid 10km if defined in the code?
Maybe we can find an other way do it?

Sure, I think, the USB-custodian will be glad to see patches.

Because static are always initialised to 0, and, in fact, checkpatch.pl produces warnings on these, and rightfully so.

why not? static int be_quiet = 0;

No. This are "recommended values" as mentioned in the comment to the table referenced above.
Bout perhaps you could add some documentation what all these magic numbers mean? Of course we can all download the documetnation, study it for hours and finally uinderstand this, too - but it would be nicer if you could save us this effort.
- u32 reg, pclk_ratio = get_PCLK() / gd->baudrate;
why not u32 reg; u32 pclk_ratio = get_PCLK() / gd->baudrate;

Indeed. But the one that is better readable is preferred.
- /* PCLK / (16 * baudrate) - 1 */
- reg = pclk_ratio / 16 - 1;
- i = pclk_ratio - (reg + 1) * 16;

Please, think again. This is integer arithmetics, not analysis.
So perhaps you want to elucidate your code in a comment?

This interface has changed in u-boot-nand-flash/testing. Can you rebase against it?

SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl driver for it too. The board can also boot from the NOR flash, but due to hardware limitations it can only address 64KiB on it, which is not enough for U-Boot. Ported from u-boot-1.1.6 version by Samsung.

- only be provided if a hardware ECC is available
- eccmode: mode of ecc, see defines
- chip_delay: chip dependent delay for transfering data from array to
- read regs (tR)
- options: various chip options. They can partly be set to inform

- explanation
- Members with a "?" were not set in the merged testing-NAND branch,
