I enable the fsl_otp feature in the kernel. and i can find /sys/fsl_otp/
I can cat the items under dir /sys/fsl_otp/. such as
i want to use "echo 0x12345678 > /sys/fsl_otp/HW_OCOTP_CFG4" (fusemap: 0x450, boot config) to burn the efuse register. is it ok?
is it one register can be programed once? if then, i should program it bit by bit because i don't konw clearly what's the right value for some bits now.
How can i program the ocotp register by bit, not 4-bytes? i means i should mask some bit while program.
