[U-Boot] Question on fitupd
Dell Customer Communication
PURPOSE: This email is with respect to the "fitupd" command. In looking at the source in the current u-boot tree, fitupd supports a NOR flash only.
OUR GOAL: We would like to expand fitupd to be able to flash a SPI NOR, and MMC block devices. This would require support for, file writes (ex. ext4write), raw block writes (ex. mmc write), etc. Our design also supports a master boot record with two bootable partitions.
QUESTIONS: Is expanding fitupd support for block devices a desirable feature to contribute back? Is this something that the u-boot projects would want?
Would you want this in the ../common path for everyone to have access to? Or, prefer that this support be added to ../board/<mystuff>/ for our unique support only?
I am leaving out all the details for now, we are first trying to understand the general direction we should go.
Thank you for any advice in this area. Brian Brelsford

This sounds useful to me. I added a few people on CC you may have more thoughts.
It would be good if this could somehow use driver model, but it would need some thought.

I've already prepared some patches (which will be accepted shortly) to extend update_tftp() function, which is used directly by fitupd command.
Please refer to the following patch series if they suit your needs:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/231775/focus=231772
In short - support for eMMC and other DFU supported mediums have been provided.
This would require support for, file writes (ex. ext4write), raw block writes (ex. mmc write), etc.
Our design also supports a master boot record with two bootable partitions.
