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.

9f35688349 sunxi: usb_phy: invert the USB phy_ctl condition
All the new SoCs from Allwinner since the A33 have had the phy_ctl offset
at 0x410 instead of 0x404 that was used on the previous SoCs.

Instead of adding more and more special cases as the number of SoCs grow,
let's invert the test to have 0x410 by default, and the (hopefully) fixed
number of old SoCs being the exception.

7b82a229e5 sunxi: prepare for sharing MACH_SUN8I_H3 config symbol
The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

9d6c9d988f sunxi: A64: enable USB support
Mostly by adding MACH_SUN50I to some existing #ifdefs enable support
for the the HCI0 USB host controller on the A64.
Fix up some minor 64-bit hiccups on the way.
Add the bare minimum DT bits to the A64 .dtsi and enable the controllers
and the PHY on the Pine64.
This is limited to the first USB controller at the moment, which is
connected to the lower USB socket on the Pine64 board.
[Andre: remove unneeded defines, enable OHCI, add commit message]

57075a472a sunxi: musb: Power off OTG port VBUS when disabled
The Linux kernel musb driver expects VBUS to be off while initializing
musb. Having it on results in a repeating string of warnings, followed
by an unusable peripheral. The peripheral is only usable after
physically removing the OTG adapter, letting musb reset its state.

This partially reverts commit c9f8947e66 ("sunxi: usb-phy: Never
power off the usb ports")

2c3c3ecb59 sunxi: Add INITIAL_USB_SCAN_DELAY Kconfig option
Some boards have on board usb devices which need longer than the USB
spec's 1 second to connect from board powerup. Add a config option which
when non 0 adds an extra delay before the first usb bus scan.

0ea5a04fbc sunxi: Explicitly cast u32 pointer conversions
Some parts of the sunxi code cast explicitly between u32 values and pointers.
This is not a problem in practice, because all 64bit SoCs today only use the
lower 32 bits for their phyical address space. But we need to make sure that
the compiler is sure this is not an accident as well.

e6e505b93c sunxi: Move cpu independent code to mach directory
Some of the code in arch/arm/cpu/armv7/sunxi is actually armv7 specific, while
most of it is just generic code that could as well be used on an AArch64 SoC.

Move all files that are not really tied to armv7 into a new mach-sunxi
directory.
