Hello all,

U-Boot provides data containing board information to a resident OS that may be booted. Are there plans to extend this so that an additional 'level' of more specific board information can be provided to the OS?

Specifically, and for example, is there a mechanism that U-Boot can use to inform the OS (Linux in this case) that it has enabled the watchdog on the cpu?

Granted, U-Boot and the OS are separate entities up to a point, ie some kernel arch set up implementations make reference to (or rather, copy) data structures in u-boot.h (eg Freescale Coldfire).

However, for custom hardware and/or applications there are definite cases where there is the requirement for more board specific knowledge to be shared between U-Boot and OS.

Is there a way to do this?

Feedback much appreciated.

Thanks, -- Matt
