Dear Marek Vasut,
In message 201009241737.27335.marek.vasut@gmail.com you wrote:
Using the DT for run-time configuration of U-Boot would be especially interesting. Assume: a single U-Boot image for all - say - OMAP3 boards...
This looks very cool. I thought about this and I came to a further idea:
- Make "minimal" u-boot that'd be independent of DTree
- Upon setting variable "fdt" to an address of the DTree, enable remaining
components of uboot
The second point would allow booting a platform in case the DTree was faulty. Or we can have a known-good DTree and a variable that'd allow to override it, that might be even better.
We will probably need something like that anyway - the "minimal configuration" being largely what is running before relocation, the "full configuration" when we have full access to normal resources.
Best regards,
Wolfgang Denk
