Subject: [RFC] UBI: MLC Support v0
Date: Mon, 30 May 2016 14:04:21 +0200 [thread overview]
Message-ID: <1464609874-15488-1-git-send-email-richard@nod.at> (raw)
as announced in [1] I'd like to submit the very first patch series to
have MLC support in UBI (and therefore also UBIFS).
The code has not changed much since the announcement but now the patches
are in a more reviewable shape. Still not mainline ready but better.
I'm sending this now as I'm on vacation until June 15th and hope that
we get some reviews on the concept.
The series consists of three parts:
a) Generic UBI rework to make the MLC implementation possible.
b) SLC emulation mode to access only lower pages on MLC NAND.
c) LEB consolidation to exploit MLC NAND's higher pages.

Thanks,
//richard
