This series is inspired by reading the following topic:

https://lore.kernel.org/buildroot/20230206230203.70e2dbd8@windsurf/T

Starting from that patch, and following Thomas Petazzoni's suggestions
regarding the possibility of using a single minimal script without
duplicating it within Buildroot, I developed these three patches.
Meanwhile, the configuration for the stm32f746_disco board was useful
for developing the display support for the board, which was later
merged into Linux.

This time the patches have been applied to Yann's series:
https://patchwork.ozlabs.org/project/buildroot/list/?series=421768
and therefore not directly to the master.

Regarding Thomas's suggestion to remove the u-boot partition:
https://patchwork.ozlabs.org/project/buildroot/patch/20240822183742.3550055-3-dario.binacchi@amarulasolutions.com/
I removed it, but the system became more unstable, so I kept the vfat
partition, as is already done in other configurations for ST boards.

Dario Binacchi (3):
  package/tinyinit: new package
  configs/stm32f746_disco_sd: new defconfig
  board/canaan/k210-soc: use tinyinit as Linux init process
