Commit Message

Dario Binacchi Aug. 22, 2024, 6:37 p.m. UTC
The initialization script provided by the tinyinit package is the same
as the one contained in board/canaan/k210-soc/rootfs_overlay/sbin/init
except for the Linux logo, which has been removed. The patch reworks
the configurations that use this overlay directory by replacing the
initialization process contained within it with the one provided by
the tinyinit package.

Changes v2 -> v3:
 - Replace BR2_INIT_TINYINIT=y with BR2_INIT_NONE=y and
   BR2_PACKAGE_TINYINIT=y in stm32f746_disco_sd_defconfig.

Changes v1 -> v2:
 - Remove the logo management.
 - Update the commit message.
