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.

e2000731ae mx6: sys_proto: Add prototypes for imx6_pcie_toggle() functions
When compiling with W=1 errors are observed:

drivers/pci/pcie_imx.c:528:12: warning: no previous prototype for ‘imx6_pcie_toggle_reset’ [-Wmissing-prototypes] __weak int imx6_pcie_toggle_reset(void)

Remove these warnings by adding the functions prototypes on arch-mx6/sys_proto.

7d289d6239 imx: add macro to detect whether USB PHY is active
This macro allows to detect whether the USB PHY is active. This
is helpful to detect if the boot ROM has previously started the
USB serial downloader.

The idea is taken from the mfgtool support in the NXP U-Boot:

Change is consistent with other SOCs and it is in preparation

This change is also coherent with the structure in kernel.

fc684e87a1 imx-common: consolidate macros and prototypes into sys_proto.h
Move most macro definitions and prototypes into
"arch/arm/include/asm/imx-common/sys_proto.h" to avoid duplicated
function prototypes and marco definitions for different i.MX SoCs.

This patch do not remove the sys_proto.h for different i.MX SoCs,
because we need to modify lots of driver code and others. This patch
remove duplicated macros and prototypes and incude "sys_proto.h"
of imx-common for each sys_proto.h of different i.MX platforms.
Then later we should avoid add stuff in sys_proto.h of each platform,
and modify driver to include common sys_proto.h.

eFUSE bits match the description within the IMX6DQRM and that they will
be added to the next revision of the respective reference manuals.

This patch moves the following functions into the imx-common

- mxs_wait_mask_set()
- mxs_wait_mask_clr()
- mxs_reset_block()

for i.MX6 will also use these functions. So lets move them to a
common location to re-use them.
