Subject: ARM: stm32: Increase USB power-good delay on DHSOM
X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=e8e66801bd512eb1e4c14efca34b7b254ad26110;p=u-boot.git

ARM: stm32: Increase USB power-good delay on DHSOM

The USB hub on STM32MP1 DHCOM boards needs to wait a bit longer until
the USB Vbus is stable. Increase the USB power-good delay to 1 s.

This adds default-undefined STM32MP_BOARD_EXTRA_ENV variable into
stm32mp15_common.h to reduce duplication in board-specific config
files adding custom environment.
