ubi: Print skip_check in ubi_dump_vol_info()

2019-10-16T03:42:27Z

It might be interesting, if "skip_check" is set or not, so lets print this flag in ubi_dump_vol_info() as well. hs: fix typo in commit message Signed-off-by: Stefan Roese Cc: Quentin Schulz Cc: Boris Brezillon Cc: Heiko Schocher Reviewed-by: Heiko Schocher

ubi: provide a way to skip CRC checks

2019-10-16T03:42:27Z

Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume. Skipping this test drastically improves the boot-time. Adapted to U-Boot by Stefan Roese.

mtd: ubi, ubifs debug: Use pr_debug instead of pr_crit

2019-04-09T05:46:42Z

Before printk.h was introduced and MTDDEBUG was removed, pr_crit() was calling MTDDEBUG(), which was since then replaced by the current pr_debug(). pr_debug is more appropriate here. Signed-off-by: Eran Matityahu Reviewed-by: Heiko Schocher

lib: Add hexdump

2018-06-13T11:49:12Z

Often during debugging session it's very interesting to see what data we were dealing with. For example what we write or read to/from memory or peripherals. This change introduces functions that allow to dump binary data with one simple function invocation like: ------------------->8---------------- print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len); ------------------->8---------------- which gives us the following: ------------------->8---------------- 00000000: f2 b7 c9 88 62 61 75 64 72 61 74 65 3d 31 31 35 ....baudrate=115 00000010: 32 30 30 00 62 6f 6f 74 61 72 67 73 3d 63 6f 6e 200.bootargs=con 00000020: 73 6f 6c 65 3d 74 74 79 53 33 2c 31 31 35 32 30 sole=ttyS3,11520 00000030: 30 6e 38 00 62 6f 6f 74 64 65 6c 61 79 3d 33 00 0n8.bootdelay=3. 00000040: 62 6f 6f 74 66 69 6c 65 3d 75 49 6d 61 67 65 00 bootfile=uImage. 00000050: 66 64 74 63 6f 6e 74 72 6f 6c 61 64 64 72 3d 39 fdtcontroladdr=9 00000060: 66 66 62 31 62 61 30 00 6c 6f 61 64 61 64 64 72 ffb1ba0.loadaddr 00000070: 3d 30 78 38 32 30 30 30 30 30 30 00 73 74 64 65 =0x82000000.stde 00000080: 72 72 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 rr=serial0@e0022 00000090: 30 30 30 00 73 74 64 69 6e 3d 73 65 72 69 61 6c 000.stdin=serial 000000a0: 30 40 65 30 30 32 32 30 30 30 00 73 74 64 6f 75 0@e0022000.stdou 000000b0: 74 3d 73 65 72 69 61 6c 30 40 65 30 30 32 32 30 t=serial0@e00220 000000c0: 30 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00.............. ... ------------------->8---------------- Source of hexdump.c was copied from Linux kernel v4.7-rc2.

Since 'commit f82290afc847 ("mtd: ubi: Fix worker handling")', when booting from NAND, on a fresh NAND just after being flashed (and only in this case), we got the following log: ubi0: default fastmap pool size: 200 ubi0: default fastmap WL pool size: 100 ubi0: attaching mtd2 ubi0: scanning is finished ubi0 error: ubi_update_fastmap: could not find any anchor PEB ubi0 error: ubi_update_fastmap: could not find any anchor PEB ubi0 error: ubi_wl_get_peb: Unable to get a free PEB from user WL pool ubi0 error: autoresize: cannot auto-resize volume 1 UBI error: cannot attach mtd2UBI error: cannot initialize UBI, error -28UBI init error 28 After analysis, in ubi_wl_init(), when performing schedule_erase(), thread_enabled flag is not yet set to 1, which forbids ubi_do_worker() to execute pending works. This has to effect to not populate ubi->free with free physical eraseblocks.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
