Hi everybody, I have a question regarding changing the eMMC boot partition size. According the the JEDEC eMMC spec it is read-only (BOOT_SIZE_MULT register).
But we still have mmc_boot_partition_size_change() in drivers/mmc/mmc_boot.c. It contains the comment /* Only use this command for raw EMMC moviNAND. Enter backdoor mode */ What is moviNAND? My research pointed me to Samsung products only. So is changing the boot partition size vendor specific or can it be used more generally? To be specific, I use the Kioxia THGBMJG6C1LBAB7 eMMC chip. Thanks and best regards, Philip Oberfichtner
