This commit adds a patch to RAUC that makes the eMMC boot partition support optional. This allows RAUC to build successfully on systems using Linux < 3.0.

Subject: [PATCH] build: make eMMC boot partition support optional
|
|
|
|
The eMMC boot partition support, added in commit
|
|
ea5cc7ff606c65536da218bd1ef6d0ca279c9b17 ("src/update_handler: add
|
|
support for updating eMMC boot partitions"), requires
|
|
<linux/mmc/ioctl.h>, only available starting from kernel headers 3.0.
|
|
|
|
Even though it is pretty likely that people are going to use Linux >=
|
|
3.0 on their embedded systems these days, RAUC also needs to be built
|
|
natively on the build machine to produce update artifacts, and the
|
|
build machine is sometimes using an ancient Linux system, especially
|
|
in an enterprise contexts.
|
|
|
|
In order to make sure that RAUC builds fine in this context, this
|
|
commit makes the eMMC boot partition support optional, by verifying
|
|
the availability of <linux/mmc/ioctl.h>.
