2018-05-22ubi: fastmap: Implement produce_free_peb()Patrice Chotard1-0/+29
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. Following Richard Weinberger's advice, this patch has been backported from kernel tree : 'commit 1cb8f9776c7d ("ubi: fastmap: Implement produce_free_peb()")' Tested-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Acked-by: Heiko Schocher <hs@denx.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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 <trini@konsulko.com>
2018-02-06ubi: Ensure no fastmap flush after uif_closeMartin Townsend1-5/+0
On detach UBI attempts to update fastmap after closing user interfaces but at this point UBI volumes have already been free()'ed and fastmap can no longer access these data structures.
