[PATCH 1/3] efi: loader: fix format string for ARM32

[Ahmad Fatoum]

size_t is an unsigned long on our ARM64, but an unsigned int on ARM32,
which causes a GCC warning when compiling this printf format string.

Switch to the appropriate %zx format specifier to fix this.

[PATCH 2/3] ARM: stm32mp: lxa: change stdout-path baud rate from 9600 to 115200

[Ahmad Fatoum]

The LXA boards are the only upstream STM32 boards that set
stdout-path = &uart* instead of explicitly specifying a baud rate.

This would mean the default of 9600 is used, but it goes unnoticed when
booting normally as barebox fixes up a console= line that includes a
baud rate.

When EFI booting GRUB however, GRUB will not pass along the console=
line and thus the board ends up with a 9600 baud Linux console,
confusing users.

A fix for this has been submitted upstream[1]. Until then, have the fix
in barebox as barebox will pass along its device tree when booting via
EFI.

[PATCH 3/3] ARM: stm32mp: enable useful options for the LXA Fairy Tux2

[Ahmad Fatoum]

The Fairy Tux 2 has a PCA953x I2C GPIO controller controlling some LEDs
as well as the reset to the dual role USB chip.

The USB-C port will be useful to boot installer images via EFI.

Enable support for these as well as other options that can prove useful.

[PATCH] fixup! ARM: stm32mp: enable useful options for the LXA Fairy Tux2

[Ahmad Fatoum]

ARM: stm32mp: enable resize command

The Debian CDROM installer resizes the terminal and rebooting into
barebox may fix the viewport at a smaller size than what the terminal
has.

Enable the resize command to allow users to make use of the full
terminal width again easily.
