Dear Amit Kucheria,
In message AANLkTi=peKHk5qWxM_JA5bm1A9=2QSkfQvy-h2Nw2sG=@mail.gmail.com you wrote:
It is not related to a specific storage. We could have a filesystem

on other storages (SPI-Flash, NAND, HD...) and "reading from file" should IMHO hide the underlying storage media.
Reading from filesystems brings up the obvious question - which filesystems should we support?
Well, reading from file system in only one part of the issue - you also need write support or you cannot implement "saveenv". And at the moment YAFFS is the only file system with write support, IIRC.
And it is definitely a separate patch. The feature that this patch is enabling can exist independent of filesystem support.
[Ghorai] This patch is very important for the platform where we don't have any other storage device; e.g. omap4 development platforms does not have any NAND/NOR to save the env. And need to use this patch.
Indeed.
Best regards,
Wolfgang Denk
