 Actually BLK_DEV_PLATFORM would handle the SWARM's platform driver as an 
IDE device, however the driver has supported libata ever since commit 
2fef357cf391 ("IDE: Fix platform device registration in Swarm IDE driver 
(v2)") back in 2008, so this is good to go.  We should probably enable 
PATA_PLATFORM in the defconfig instead.

 The printed name of the driver could be improved I suppose though:

scsi host0: pata_platform
ata1: PATA max PIO0 mmio cmd 0x100b3e00 ctl 0x100b7ec0 irq 36

(PIO3 is actually hardwired; it's an odd interface and people reported 
issues with it, but I have never had any myself be it with IDE or libata).
