Joe Hershberger	76c1637e95	ubi: Fix broken cleanup code in attach_by_scanning ... The unwind code was not reversing operations correctly and was causing a hang on any error condition. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>	2013-04-11 15:52:54 -04:00
Stefan Roese	1b1f9a9d00	UBI: Ensure that "background thread" operations are really executed ... The current U-Boot UBI implementation is copied from Linux. In this porting the UBI background thread was not handled correctly. Upon write operations ubi_wl_flush() makes sure, that all queued operations, like page-erase, are completed. But this is missing for read operations. This patch now makes sure that such operations (like scrubbing upon bit-flip errors) are not queued, but executed directly.

Kyungmin Park	c91a719daa	UBI: Add basic UBI support to U-Boot (Part 5/8) ... 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.
