* mtd: Add subpagesize to mtd_info_userSascha Hauer2013-12-201-0/+1
| | | | | | | | | ubiformat needs the subpagesize to work correctly. The kernel uses sysfs to pass the subpagesize, but in barebox we have the possibility to extend struct mtd_info_user. Add a corresponding field and use it in ubiformat. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Fix endless loop in automount codeSascha Hauer2013-11-271-0/+2
| | | | | | | | | | A chdir to a path registered as an automount path followed by a 'ls' results in an endless loop. This happens because the command the automounter executes results in another automount request. Fix this by running the automounter from the chdir code before the cwd is actually changed.

| * fs: cleanup backingstore handlingSascha Hauer2013-09-295-48/+45
| | | | | | | | | | | | | | | | | | | | | | All filesystem drivers which need a backingstore device do the same ignoring of '/dev/' in the backingstore followed by a cdev_open. Add a helper function for it and let the core handle the cdev. As a side effect this makes sure that fsdev->cdev is also set when a device is mounted without the leading '/dev/' which was previously ignored by the mount code.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simple update file format developed for Somfy, tools and library are available under LGPLv2 (https://www.gitorious.org/libbpk). This format in the v1.0 allow you to store 6 types a binary stream for a unique hardware id: - bootloader - bootloader_version - description.gz - kernel - rootfs - firmware_version and you can easly add more binary stream type. The fs will display you in a directory per hw id and if a binary stream type is unknown will be display as unknown_%08x # mount image.bpk /tmp # ls -l /tmp/hw_id_0/ -rwxrwxrwx 10 firmware_version -rwxrwxrwx 8 firmware_version.crc -rwxrwxrwx 1845968 kernel -rwxrwxrwx 8 kernel.crc -rwxrwxrwx 5062656 rootfs -rwxrwxrwx 8 rootfs.crc -rwxrwxrwx 248 bootloader -rwxrwxrwx 8 bootloader.crc -rwxrwxrwx 248925 description.gz -rwxrwxrwx 8 description.gz.crc -rwxrwxrwx 4 bootloader_version -rwxrwxrwx 8 bootloader_version.crc -rwxrwxrwx 4 unknown_1234567g -rwxrwxrwx 8 unknown_1234567g.crc Why BPK and not CPIO or uImage 1) CPIO cpio does not handle > 4GiB image and does not have any crc checksum 2) uImage uImage only provide one crc32 for the all data part and only a list of binary stream with no information about what is what (in multi-image format) 3) BPK BPK provide a crc32 for the header part and one crc32 per binary stream so if you does not care of some data you are not force to check them And you known exactly the binary stream type and for which hw to use it.
