* regulator: Add pfuze driverSascha Hauer2017-01-201-0/+6

* mci: Allow to partition eMMC boot partitionsSascha Hauer2017-01-191-0/+1
| | | | | | | | | So far the eMMC boot partitions cannot be partitioned from the device tree. Since they are often 4MiB in size they are big enough to hold a barebox image and the environment. Add partition parsing to the boot partitions to allow this usecase. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds `filetype_squashfs` to the list of known filetypes and adds a detection for squashfs files to file_detect_type(). This currently matches on the `hsqs` start sequence of an image file. Additionally, the newly introduced filetype is registered as the type of the squashfs_driver which allows, for example, to mount squashfs without the need to specify a type parameter. This changes enable booting a squashfs with the simple `boot` command pointing to the location (device) that holds the squashfs. Note that booting with blspec is limited as the current squashfs driver is not capable of handling symbolic links.

* | boot: add framework for redundant boot scenariosMarc Kleine-Budde2016-09-221-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several use cases where a redundant Linux system is needed. The barebox bootchooser framework provides the building blocks to model different use cases without the need to start from the scratch over and over again. The bootchooser works on abstract boot targets, each with a set of properties and implements an algorithm which selects the highest priority target to boot. See the documentation contained in this patch for more information.

* | globalvar: sync with nvvarsSascha Hauer2016-09-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the behaviour when a driver creates a globalvar using globalvar_add_simple_[string|int|bool|enum|ip]) *after* nvvars are initialized and this globalvar is overwritten with a nvvar. Currently this fix is not needed because all globalvars are registered before the nvvars are initialized. We have two different typed of globalvars. The first type, here referred to as qualified globalvars, has a backend variable storage (the ones created with globalvar_add_simple_[string|int|bool|enum|ip]), the other created with globalvar_add_simple only has a dynamically allocted string as backend. Normally during startup of barebox the qualified globalvars are registered and during load of nvvars are synced with the values from the nvvars. Everything works fine in this case. However, when during nvvar initialisation a globalvar for a nvvar does not exist, then it is registered as unqualified globalvar. When then later some driver wants to register a qualified globalvar for which a unqualified globalvar already exists, it will get a -EEXIST. This is not the expected behaviour. Instead, the current unqualified globalvar should be removed, recreated as qualified globalvar and then afterwards synced with the corresponding nvvar. This behaviour is fixed with this patch.
