[U-Boot] [PATCH 07/11 v4] UBI: Add basic UBI support to U-Boot (Part 6/8)
Stefan Roese
sr at denx.de
Wed Nov 19 20:39:21 CET 2008
From: Kyungmin Park <kyungmin.park at samsung.com>
This patch adds basic UBI (Unsorted Block Image) support to U-Boot.
It's based on the Linux UBI version and basically has a "OS"
translation wrapper that defines most Linux specific calls
(spin_lock() etc.) into no-ops. Some source code parts have been
uncommented by "#ifdef UBI_LINUX". This makes it easier to compare
this version with the Linux version and simplifies future UBI
ports/bug-fixes from the Linux version.
