Hi,
Now we implemented the mobile storage and want to posting it to mmc.
But during code review I know that it's almost similar with sdhci core
except register offset and fifo support.
So I wonder what's the better way to implement it.
1) create the mstorage.[ch]
2) override the existing sdhci using io accessors function.
Basic Mobile Storage Host controller register is following.
CTRL: 0x0000
PWREN: 0x0004
CLKDIV: 0x0008
CLKSRC: 0x000C
CLKENA: 0x0010
TMOUT: 0x0014
CTYPE: 0x0018
BLKSIZ: 0x001C
BYTCNT: 0x0020
INTMASK: 0x0024
CMDARG: 0x0028
CMD: 0x002C
...
Any comments are welcome.
Thank you,
Kyungmin Park
