Yes, thanks.

I agree that it's too time consuming (usually) for a manufacturing test.
Either you are okay with disabling CONFIG_SYS_ALT_MEMTEST on your board,
which will also disable this bitflip test. Or please continue adding a
new Kconfig option for it - which is probable the better option.

Thanks,
