The basic problem here that pata_legacy attaches the host, sees if it found
any devices and detaches it if none were found. With async probing, it's not
waiting until discovery is finished before deciding it has no devices and
trying the detach leading to this warning:
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14

Because it detaches before the probe is complete.
One way to fix it would be to put an async_synchronize_full() before looking
for devices, which this patch does. A better way might be to separate libata
into its own domain and only wait for that.

The ConnectX Programmer's Reference Manual states that the "SO" bit
must be set when posting Fast Register and Local Invalidate send work
requests. When this bit is set, the work request will be executed
only after all previous work requests on the send queue have been
executed. (If the bit is not set, Fast Register and Local Invalidate
WQEs may begin execution too early, which violates the defined
semantics for these operations)

Due to a processor anomaly (05000263 to be exact), most Blackfin parts
cannot keep the embedded filesystem image directly after the kernel in
RAM. Instead, the filesystem needs to be relocated to the end of memory.
As such, we need to tweak the map addr/size during boot for Blackfin
systems. This can be done in any early arch/board init code.

Scan order is:

2) chip.set_parts
3) chip.partitions
4) full mtd device (fallback for no partitions)

portable solution is to use an initramfs instead.
The only user of this function was the msp71xx configuration
