db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

5c6e497eaa arm: dra7xx: Hang on any failure during IOdelay recalibration
If there is any failure during IOdelay recalibration sequence, IOs are
not guaranteed to behave as expected. So hang on any failure during the
sequence.

60e3d43a26 arm: dra7xx: Fix error path in iodelay recalibration
When an error is reported in __recalibrate_iodelay_start(), de-isolation
of IO doesn't happen. Because of this, undefined behaviour is observed
on many peripherals without any error. So make sure io is out of isolation
at the end of iodelay recalibration.

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.

6a27333ba3 ARM: OMAP5/DRA7: Enable iodelay recalibration to be done from uboot
Add a new API to perform iodelay recalibration without isolate
io to be used in uboot.

The data manual of J6/J6 Eco recommends to set different IODELAY values
depending on the mode in which the MMC/SD is enumerated in order to
ensure IO timings are met. The MMC driver can use the new API to
set the IO delay values depending on the MMC mode.

983e37007d arm: Introduce arch/arm/mach-omap2 for OMAP2 derivative platforms
This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories.  All refernces to the former locations are updated to
the current locations.  For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.
