Hi,
We are doing the boot time optimization on target board which has the emmc device as a storage device. Have observed that ext4 filesystem mounting takes longer time (750ms) and want to reduce this time. Already emmc runs with HS400 mode. Please find the below log,
[ 0.623431] mmc0: new HS400 MMC card at address 0001[ 0.624105] mmcblk0: mmc0:0001 S0J35A 7.28 GiB
