msaitoh | Change MII PHY read/write API from:
int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:
int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);
Now we can test if a read/write operation failed or not by the return value.
In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.
Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

chris | Remove changes to bitbang code for de devices to work as tlps on cats.
I need to investigate a proper fix that doesn't break other platforms, eg:

chris | Following feedback from thorpej, remove the #ifdef cats block, and update
comment.
All platforms will now send a change in direction, then the 32 MDO bits
when synchronising with the phy. Rather than sending the change in
direction with the first MDO bit.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
