[PATCH 0/5] add createnv command to create environment partition

[Sascha Hauer <s.hauer@pengutronix.de>]

We want to move away from describing the barebox environment explicitly
in the device tree and instead motivate usage of GPT partitions for the
envrionment. This series creates a createnv command to facilitate this.
It creates an environment partition on the specified device and if
necessary also a GPT partition table. In the simplest case a "createnv"
without arguments will create a partition on the device barebox itself
booted from. Both the device and the size of the partition can be
specified on the command line.

As the first GPT partition as well as the GPT partition entries might
conflict with a barebox written on the device on certain SoCs this
series also includes patches to move the first partition up to the 8MiB
boundary leaving space for a barebox binary written onto the raw device.
On Some SoCs (i.MX7 and earlier) the GPT partition entries also collide
with the barebox binary, so these are moved up to just below the 8MiB
boundary.
