[U-Boot] Support for NANDs greater than/equal to 4 GB
Scott,
There was a patch some time which added the 64 bit support in the MTD subsystem. I am referring to the patch below
http://git.infradead.org/mtd-2.6.git/blobdiff/8a4c2495b142fe612b291a810d9e69...
This feature still is not part of U-Boot. Is it going to be added?
Without this NANDs of size greater than equal to 4 GB fail to get recognized.
Thanks, Sandeep

Was it submitted to U-Boot? If it was, I missed it.

If someone submits a patch, yes. Otherwise it'll get picked up the next time I sync with Linux.

Scott, Please see inline

[Sandeep] Please tell me the U-boot policy of picking features from the kernel. I submitted 2 NAND/MTD patches yesterday which were accepted by Andrew Morton. Since I am in the signed-off-by, I sent the patches to U-boot as well.
But the above support in question is not my patch

[Sandeep] Can I do it? That's my question. BTW I have tried it myself, it does not seem to be a trivial feature addition. Changes will also be required in the files in the /common folder which relates to NAND.
That brings me to my final point are the patches I sent yesterday [PATCH 1/2] NAND: ADD page Parameter to all read_page/read_page_raw API's [PATCH 2/2] MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRST
Going to be accepted by you?

Thanks, Sandeep

I try to sync every now and then, but if you need something sooner please send it as a patch.

That's OK -- just send it with the author in a From: line at the beginning of the patch (but not in the e-mail headers).

Sure.

I've been busy on non-U-boot stuff, and haven't had a chance to look at them in detail yet. I'll try to get to them soon.
