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.

This adds the reset support for the following devices that was until
then not implemented:
- BFTIC4
- QSFPs
This also fixes the configuration of the prst behaviour for the other
resets: Only the u-boot and kernel relevant subsystems are taken out of
reset (pcie, ZL30158, and front eth phy).
Most of the prst config move to misc_init_f(), except for the PCIe
related ones that are in pci_init_board and the bftic and ZL30158 ones
that should be done as soon as possible.
Only the behavior of the Hooper reset is changed according to the
documentation as the application is not able to not configure the switch
when it is not reset.

Add readout of dip-switch to revert to factory settings.
If one or more dip-switch are set, launch bank 0 that contains the
bootloader to do the required action.

The unit LEDs are managed by the QRIO CPLD. This patch adds support for
accessing these LEDs in the QRIO.
The LEDs then are set to a correct boot state:
- UNIT-LED is red
- BOOT-LED is on.

The QRIO GPIO functions can be of general interest. They are thus added
to a qrio.c and their prototype are available from kmp204x.h. The QRIO
prst function are also included in this file, as well as the functions
required for the I2C deblocking support (open-drain).

[York Sun: Remove extra blank line in board/keymile/kmp204x/qrio.c]
Signed-off-by: York Sun <yorksun@freescale.com>
This patch introduces the support for Keymile's kmp204x reference
design. This design is based on Freescale's P2040/P2041 SoC.
The peripherals used by this design are:
- DDR3 RAM with SPD support
- SPI NOR Flash as boot medium
- NAND Flash
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
FPGA
- 2 HW I2C busses
- last but not least, the mandatory serial port
The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb
support and was changed according to our design (that means essentially
removing what is not present on the designs and a few adaptations).
There is currently only one prototype board that is based on this design
and this patch also introduces it. The board is called kmlion1.
