"Drop ffs" functionality in MTD DFU backend

Hello all,

I am using u-boot on a STM32MP1 EV1 board. Until recently, the NAND DFU backend was used to flash UBI images to the board. I used the DFU_NAND_TRIMFFS option to ensure that the UBI image was correctly flashed to NAND.

Recently, ST has switched from the NAND DFU backend to the MTD DFU backend. Is there a way to tell the MTD subsystem to do the same (drop trailing all-0xff pages) in order to flash UBI images to raw NAND?

Thank you,
