Some filesystem references got broken by a previous patch series I submitted. Address those.

2018-02-08cramfs: better MTD dependency expressionNicolas Pitre1-2/+1
Commit b9f5fb1800d8 ("cramfs: fix MTD dependency") did what it says. Since commit 9059a3493efe ("kconfig: fix relational operators for bool and tristate symbols") it is possible to do it slightly better though.

2017-12-17cramfs: fix MTD dependencyArnd Bergmann1-0/+1
With CONFIG_MTD=m and CONFIG_CRAMFS=y, we now get a link failure: fs/cramfs/inode.o: In function `cramfs_mount': inode.c:(.text+0x220): undefined reference to `mount_mtd' fs/cramfs/inode.o: In function `cramfs_mtd_fill_super': inode.c:(.text+0x6d8): undefined reference to `mtd_point' inode.c:(.text+0xae4): undefined reference to `mtd_unpoint' This adds a more specific Kconfig dependency to avoid the broken configuration. Alternatively we could make CRAMFS itself depend on "MTD || !MTD" with a similar result.

Update documentation, pointer to latest tools, appoint myself as maintainer. Given it's been unloved for so long, I don't expect anyone will protest. Signed-off-by: Nicolas Pitre <nico@linaro.org> Tested-by: Chris Brandt <chris.brandt@renesas.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2017-10-15cramfs: direct memory access supportNicolas Pitre1-1/+29
Small embedded systems typically execute the kernel code in place (XIP) directly from flash to save on precious RAM usage. This patch adds to cramfs the ability to consume filesystem data directly from flash as well. Cramfs is particularly well suited to this feature as it is very simple with low RAM usage, and with this feature it is possible to use it with no block device support and consequently even lower RAM usage. This patch was inspired by a similar patch from Shane Nay dated 17 years ago that used to be very popular in embedded circles but never made it into mainline. This is a cleaned-up implementation that uses far fewer ifdef's and gets the actual memory location for the filesystem image via MTD at run time. In the context of small IoT deployments, this functionality has become relevant and useful again.
