* mtd, ubi: set free_count to zero before walking through erase listHeiko Schocher2016-04-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | Set free_count to zero before walking through ai->erase list in wl_init(). As U-Boot has no workqueue/threads, it immediately calls erase_worker(), which increase for each erased block free_count. Without this patch, free_count gets after this initialized to zero in wl_init(), so the free_count variable always has the maybe wrong value 0. Detected this behaviour on the dxr2 board, where the UBI fastmap gets not written when attaching/dettaching on an empty NAND. It drops instead the error message: could not find any anchor PEB With this patch, fastmap gets written on dettach.

* kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada2014-09-16-1/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

* UBI: Ensure that "background thread" operations are really executedStefan Roese2010-05-19-2/+7
| | | | | | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>
* UBI: Add basic UBI support to U-Boot (Part 5/8)Kyungmin Park2008-11-19-0/+1670
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.
