83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

1221ce459d treewide: replace #include <asm/errno.h> with <linux/errno.h>
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

307c0b5189 gpio: mxs: Remove netdev.h
The MXS certainly does not support any sort of networking in GPIO code,
remove the netdev.h header.

88f91d1375 gpio: mxs: add name_to_gpio() function
Override the default name_to_gpio() function with one that
accepts strings of the form bank:pin.  If a colon is present
in the provided name, it behaves like the default version.

This lets the "gpio" command work with sane names rather than
requiring the user to enter the bank/pin composite in decimal.

ac135f6699 mxs_gpio: fix the handling in gpio_direction_output()
Setting the direction and an output value should be done by
1) set the desired output value,
2) switch to output.

If this is done in the inverse order, there can be a glitch on
the GPIO line.

This patch fixes this by using the order as described above.
