* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Fix "ubi part" cmd re-entrancyKarl Beldan2010-09-27-0/+1
| | | | | | | | | Commit 2ee951ba (UBI: Enable re-initializing of the "ubi part" command) reset mtd_devs in ubi_exit() but missed ubi_init()'s failure path. Signed-off-by: Karl Beldan <karl.beldan@gmail.com> Cc: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
* UBI: initialise update markerPeter Horton2010-06-23-0/+1
| | | | | | | | | | | | | | UBI: initialise update marker The in kernel copy of a volume's update marker is not initialised from the volume table. This means that volumes where an update was unfinnished will not be treated as "forbidden to use". This is basically that the update functionality was broken.

* 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: Fix build problem noticed on Apollon (arm/testing repo)Stefan Roese2009-07-07-1/+1
| | | | | | | | | This patch fixes a build problem noticed on Apollon by using mtd_dev_by_eb() instead of "/" as done in the Linux UBI version. So this brings the U-Boot UBI version more in sync with the Linux version again. Signed-off-by: Stefan Roese <sr@denx.de>
* UBI: Add compile-time check for correct malloc area configurationStefan Roese2009-06-12-0/+4
| | | | | | | | UBI is quite memory greedy and requires at least approx. 512k of malloc area. This patch adds a compile-time check, so that boards will not build with less memory reserved for this area (CONFIG_SYS_MALLOC_LEN). Signed-off-by: Stefan Roese <sr@denx.de>

* UBI: Enable re-initializing of the "ubi part" commandStefan Roese2008-12-09-0/+1

* UBI: Add basic UBI support to U-Boot (Part 5/8)Kyungmin Park2008-11-19-0/+3810
| | | | | | | | | | | | | 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.
