8ee54672df gpio: atmel_pio4: give a full configuration when muxing pins
When a pin is muxed to a peripheral or as a GPIO, the only
configuration that can be set is the pullup. It is too restrictive
so this patch allows to give a full configuration.

4549e789c1 SPDX: Convert all of our multiple 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 multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style

In part due to community overlap, in part due to better tag visibility

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.

mx7dsabresd_secure_defconfig was introduced to allow booting NXP kernel

Instead of keeping two different config targets for the same board,
remove mx7dsabresd_secure_defconfig and select
CONFIG_ARMV7_BOOT_SEC_DEFAULT inside mx7dsabresd_defconfig so that
this target could be used to boot both mainline and the vendor kernel.

This makes maintenance task easier and avoid potentially confusion

9c260e862f warp7: hab: Add a CSF location definition
In order to correctly produce an image with a IVT/DCD header we need to

All we have to do with this option switched on is "make u-boot.imx" and we
then will get

- u-boot.imx.log

The log file is really important because it gives the addresses for the HAB
that we will require to sign the u-boot image using the CST. Since the
addresses can change this logfile is a critical output.

852cc548b3 warp7: Set u-boot serial# based on OTP value
u-boot has a standard "serial#" environment variable that is suitable
for storing the iSerial number we will supply via the USB device
descriptor. serial# is automatically picked up by the disk subsystem in
u-boot - thus providing a handy unique identifier in /dev/disk/by-id as
detailed below.

Storing the hardware serial identifier in serial# means we can change the
serial# if we want before USB enumeration - thus making iSerial automatic
via OTP but overridable if necessary.

This patch reads the defined OTP fuse and sets environment variable
"serial#" to the value read.

With this patch in place the USB mass storage device will appear in
/dev/disk/by-id with a unique name based on the OTP value. For example

/dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0:0

Add JTAG recovery support into the M2 Porter TPL. This allows the

1) Load u-boot-tpl.bin to 0xe6300000
2) Write magic number 0x1337c0de to 0xe6300020
   TPL checks for this particular magic and starts JTAG recovery
   if this number is present. This is not present by default.
3) Start U-Boot TPL from 0xe6300000
4) Wait for a message from TPL on UART indicating JTAG boot:
   "JTAG boot detected!"
5) Halt the system in JTAG debugger
6) Load U-Boot image (u-boot.img) to 0x4fffffc0
7) Write magic number 0xb33fc0de to 0xe6300024
   TPL checks for this particular magic to verify that the U-Boot
   image was loaded into DRAM by the JTAG debugger.
8) Resume the system in JTAG debugger

9a5483e9df ARM: rmobile: Add TPL support on R8A7791 M2 Porter
Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due
to the Gen2 BootROM restriction. The TPL is running from MERAM and
is capable of performing the initial initialization of PFC, Clock,
GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up
the DDR DRAM access. The TPL is capable of loading the next stage,
U-Boot, from either SPI NOR or UART as a fallback. If either does
provide a valid U-Boot uImage, the system stops, which allows the
operator to load U-Boot ie. via JTAG and start it manually.
