Hi Brian,
I don't think it should be a problem adding a write capability in this structure.
What other framework or driver do you plan to use under this framework?
AFAIK, STM32MP1 is the only platform for the moment to use this framework. Is your project based on this SoC, or is it another platform?
Best regards, Yann

Hello,
A project I’m working on requires write capability for a NOR flash device in BL2 (to update a small boot mux partition). I am considering adding this capability to the IO MTD layer (https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/io/...), but before doing so wanted to confirm this is in line with the architecture of this subsystem. Can someone confirm if this is an acceptable change?
Regards, Brian
