Could send your comments/views.
Not sure if I understood you correctly. So I have to ask some questions:
Firstly, apologies from my side by sending too many status updates that makes you confusion.
No problem. I have been slow on reacting.
Did you use this patch?
Yes, I have applied the same patch,
http://patchwork.ozlabs.org/patch/140863/
Did it apply without issues to mainline U-Boot? Or did you have to make some changes so that it can be applied? And did it fix the issues you have seen before?
I have manually applied those changes as the index values are differ. I haven't added any newly code other than the patch changes.
If you had to make some changes to this patch, then please send the changes / updated patch version as a new version (v3) to the list. So that it applies clean now. And please change the commit text accordingly.
Please find that I have sent a v3 patch titled as: mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support Tested on two flashes 256M29EW, 512M29EW work fine.
Yes it fixed the error by detecting correct manufacture and device ID.
Only that? IIRC, then without this patch, writing to the 8-bit flash didn't work at all. But I don't have such a board, so I can't really test myself.
And did you have some make some further changes as well?
And apart from these patch change, I have changed one more this for numonyx M29EW fix for incorrect write buffer size..any way that I could send once these changes are pushed/reviewed.
Please send this additional change/fix as a separate patch to the list as well.
I sent one patch for this titled as: mtd: cfi_flash: Write buffer size adjustment for M29EW Numonyx devices
Please review and let me know for any issues/comments.
Thanks, Jagan.
