                              ^^^^^^1
Apparently, this is wrong for the else statement, since there is no CD
for the SD4 on the board,
so, we have to tell MMC system that the card is always there,
otherwise, we can't use the MMC
plug-in that slot. After change to new prototype, we also need convert
the ret value for the SD4,
and return 1 not 0 to MMC.
