Move the main symbol for Freescale Fman Ethernet controller option to

a0aba8a2eb CONFIG_SYS_[DI]CACHE_OFF: convert to Kconfig
CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig
parameters; only for the ARC architecture. This patch turns these two
parameters into Kconfig items everywhere else they are found.

All of the include/configs/* and defconfig changes in this patch are
for arm machines only. The Kconfig changes for arc, nds32, riscv,
and xtensa have been included since these symbols are found in code
under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined
include/configs/* or defconfigs for these architectures exist which
include these symbols.

These results have been confirmed with tools/moveconfig.py.

d1c3d8bdfa MIPS: start.S: make boot config at offset 0x10 configurable
Some MIPS systems store some board-specific boot configuration
in the U-Boot binary at offset 0x10. This is used by Malta boards
and by Lantiq/Intel SoC's when booting from parallel NOR flash.

Convert the hard-coded values to Kconfig options to remove such
board-specific stuff out of the generic start.S code. This also
deprecates the config option CONFIG_SYS_XWAY_EBU_BOOTCFG.

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.

b30c419040 Move CONFIG_PHY_ADDR to Kconfig
CONFIG_PHY_ADDR is used for old-style configuration. This makes
impossible changing the PHY address, if multiple boards share a same
config header file (for example include/configs/sunxi-common.h).

Moving this to Kconfig helps overcoming this issue. It's defined
as entry inside PHYLIB section.

After the implemention, moveconfig was run. The issues are:
	- edb9315a	- CONFIG_PHYLIB is not enabled. Entry is
			  deleted.

	- ds414		- CONFIG_PHYLIB is in incompatible format:
			  { 0x1, 0x0 }. This entry is also deleted.

	- devkit3250	- The PHY_ADDR is in hex format (0x1F).
			  Manually CONFIG_PHY_ADDR=31 is added in
			  the defconfig.

After the changes the suspicious defconfigs passes building.
