Like x86, armsr is frequently virtualized, and is used for development
and debugging. Kernel messages should be more readily apparent by
default. This can be achieved by adding console=tty1 to the kernel
command line, enabling the console on a (possibly virtual) display and
keyboard, in addition to a serial port.
This also enables failsafe on tty1. Failsafe mode operates on consoles
known by the kernel, without regard to /etc/inittab.
armsr's /etc/inittab is also updated to specify tty1 instead of tty0.
tty1 is technically more correct: tty1 is the first virtual console,
where tty0 reflects the current active virtual console (which is likely
to be tty1).
This configuration matches x86, which is another target commonly used
for virtualization, development, and debugging in the same way. x86's
kernel command line had specified console=tty0, although console=tty1 is
more correct for the reasons given above. This also brings x86's kernel
command line console= into agreement with its /etc/inittab, which
already used tty1.

Due to a change in kernel 6.2, the GPIO numbers on certain
architectures (including arm64) have changed. This script
will update any defined GPIO switches to the new numbering.
See https://lists.openwrt.org/pipermail/openwrt-devel/2024-March/042448.html
for more information.
In the future, the GPIO switch mechanism will likely be
replaced with something using libgpiod.

A change in kernel 6.2[1] caused the base numbers of GPIOs to
change significantly on some architectures like aarch64.
We have to number our GPIOs accordingly.
Ideally the board.d scripts should look through sysfs
to find the basenum (like cat "/sys/devices/platform/soc/2000000.i2c/
i2c-0/0-0076/gpio/gpiochip640/base"), but the problem is
that this occurs before modules are loaded, meaning I2C and other
runtime devices may be missing.

Some platforms have their console on other ports than ttyS0, so
allow the developer to tailor this on bespoke platform images.
Fixes issue #13401.

Now that the armvirt target supports real hardware, not just
VMs, thanks to the addition of EFI, rename it to something
more appropriate.
'armsr' (Arm SystemReady) was chosen after the name of
the Arm standards program.
The 32 and 64 bit targets have also been renamed
armv7 and armv8 respectively, to allow future profiles
where required (such as armv9).
