Intel LGM SoC , it's new x86 ATOM based SoC, IP itself completely

if we port then it would be ugly and also what are the problem may occur
we do not know.

There are different features involved and lines of code is more, if weHow about retro-fitting the xway logic into your driver then? I mean,
add new driver patches over xway-nand driver
adding a 100 lines of code to your driver to get rid of the 500+ lines
we have in xway_nand.c is still a win.
is completely looks ugly and it may disturb the existing functionalityHow ugly? Can you show us? Maybe we can come with a solution to make it
as well since we don't have platform to validate:'(.
less ugly.
As for the testing part, there are 4 scenarios:
1/ Your changes work perfectly fine on older platforms. Yay \o/!
2/ You break the xway driver and existing users notice it before this
series gets merged. Now you found someone to validate your changes.
3/ You break the xway driver and none of the existing users notice it
before the driver is merged, but they notice it afterwards. Too bad
this happened after we've merged the driver, but now you've found
someone to help you fix the problem :P.
4/ You break things for old platforms but no one ever complains about
it, either because there's no users left or because they never
update their kernels. In any case, that's no longer your problem.
Someone will remove those old platforms one day and get rid of the
unneeded code in the NAND driver.
What's more likely to happen is #3 or #4, and I think the NAND
maintainer would be fine with both.
Note that the NAND subsystem is full of unmaintained legacy drivers, so
every time we see someone who could help us get rid or update one of
them we have to take this opportunity.
