* 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.

* bug.h: move BUILD_BUG_* defines to include/linux/bug.hMasahiro Yamada2016-01-25-0/+1
| | | | | | | | | | | | | | | | BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

* include/linux/byteorder: import latest endian definitions from linuxKim Phillips2012-11-04-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)). This fixes arch/powerpc/lib/bootm.c: bootm.c:329:16: error: attribute '__attribute__': unknown attribute bootm.c:329:16: error: expected ')' before '__attribute__' bootm.c:329:25: error: expected identifier or '(' before ')' token powerpc sparse builds yield: include/common.h:356:22: error: marked inline, but without a definition the unknown-reason inlining without a definition is considered obsolete given it was part of the 2002 initial commit, and no arm version was 'fixed.' also fixed: ydirectenv.h:60:0: warning: "inline" redefined [enabled by default] and: Configuring for devconcenter - Board: intip, Options: DEVCONCENTER make[1]: *** [4xx_ibm_ddr2_autocalib.o] Error 1 make: *** [arch/powerpc/cpu/ppc4xx/libppc4xx.o] Error 2 powerpc-fsl-linux-size: './u-boot': No such file 4xx_ibm_ddr2_autocalib.c: In function 'DQS_autocalibration': include/asm/ppc4xx-sdram.h:1407:13: sorry, unimplemented: inlining failed in call to 'ppc4xx_ibm_ddr2_register_dump': function body not available 4xx_ibm_ddr2_autocalib.c:1243:32: sorry, unimplemented: called from here and: In file included from crc32.c:50:0: crc32table.h:4:1: warning: implicit declaration of function '___constant_swab32' [-Wimplicit-function-declaration] crc32table.h:4:1: error: initializer element is not constant crc32table.h:4:1: error: (near initialization for 'crc32table_le[0]') Signed-off-by: Kim Phillips <kim.phillips@freescale.com> [trini: Remove '#endif' in include/common.h around setenv portion] Signed-off-by: Tom Rini <trini@ti.com>
* UBI: init eba tables before wl when attaching a deviceHolger Brunck2011-10-12-6/+6
| | | | | | | | | | | | | | | | | | | This fixes that u-boot gets stuck when a bitflip was detected during "ubi part <ubi_device>". If a bitflip was detected UBI tries to copy the PEB to a different place. This needs that the eba table are initialized, but this was done after the wear levelling worker detects the bitflip. So changes the initialisation of these two tasks in u-boot. This is a u-boot specific patch and not needed in the linux layer, because due to commit 1b1f9a9d00447d UBI: Ensure that "background thread" operations are really executed we schedule these tasks in place and not as in linux after the inital task which schedule this new task is finished.

* 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>

* 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.
