Dear Matthew Lear,
In message 4A532251.8090906@bubblegen.co.uk you wrote:
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?
There are no such plans, other than converting more and more architectures to use the device tree to pass such information, which inherently is extensible.
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?
Use the device tree.
Best regards,
Wolfgang Denk
