mci: Fix version numbers again ...

The SD and eMMC version numbers are a pain to print and sort, since
they are inconsistent in if a two digit minor version shdoulde be
treated as a single number or as minor and micro version numbers.

This allows version 1.10 and 4.5 and 4.41, where 41 is less than 5.

syscon: Do not return NULL when driver is not selected ...

Both syscon_base_lookup_by_pdevname() and
syscon_base_lookup_by_phandle(), when implemented, do not return NULL,
so none of the code using those function is written to check for that.

Change returns to ERR_PTR(-ENOSYS), to avoid having that problem.

drivers: Introduce AIODEV subsystem ...

AIODEV/Aiodevice is a analog I/O framework that can be thought of as a
simplified hybrid between 'hwmon' and 'IIO' subsystems of Linux kernel

This commit is very heavily based on 'iodevice' framework proposal
written by Sascha Hauer.

bootm: Add verify mode "available" ...

The verify "available" mode checks whatever is available in the
booted image, so when an image has a signature, it is checked and
must be correct and when an image is hashed, it is also checked
for correctness.

bootm: Move bootm options to common/Kconfig ...

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

mtd: nand: Enable subpage reads ...

Until now we did not support subpage reads for smaller binary sizes.
Scanning UBI volumes on large page NANDs can be painfully slow,
subpage reads can speed this up significantly, so enable subpage reads.

Similar to what the kernel does in e004debda (mtd: nand: add "page" argument for

connected via a fixed link. This patch adds support for a fixed phy
configured through device tree.

bootm: Optionally add a root= option to Kernel command line ...

It becomes a common case that the Kernel is loaded from the filesystem
which later becomes the rootfs. This adds a possibility to let bootm
automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

string: Introduce strtobool ...

We have at least two places which convert a string to a boolean type,
so create a common function for this. strtobool treats

- any positive (nonzero) number as true
- "0" as false
- "true" (case insensitive) as true
- "false" (case insensitive) as false

Every other value results in an error and the input *val is not
modified. The caller is expected to initialize *val with the correct
default before calling strtobool.

PCI: imx6: Add proper i.MX6+ reset sequence ...

I.MX6+ version of the silicon exposed PCIe core's reset signal as a bit
in one of the control registers. As a result using old, pre-i.MX6+,
reset sequence on i.MX6+ leads to Barebox hanging during startup. Using
exposed reset bit instead solves the problem.

fix erasing/protecting flashes with unspecified size ...

fixes: 81737c1 mtd: Fix erasing of devices >4GiB

Several places erased a complete flash partition passing ~0 as count to
erase(). With the above commit count to erase was changed from an unsigned
type to a signed type, so the (count > f->size - offset) check in
erase() no longer triggers and the ~0 count is no longer adjusted to the whole
device size. Among other things this results in saveenv failures on NOR
flashes.
This patch fixes this by introducing an explicit macro for erasing the
whole device which is tested for in erase(). All other negative values
are rejected.
