[PATCH] sata_svw: Add support for new device IDs
BCM5785 (HT1000) is a new southbridge from Serverworks/Broadcom that incorporates 4 SATA ports in a single PCIX function. Functionally these ports are similar to that in older devices like the Apple K2 and the Frodo4/8. This patch adds support for the new PCI device ID along with a blurb on what the various device IDs mean. Additionally in all devices based on this SATA controller, the SATA ports appear as a single PCI function. This is true for older Frodo8 devices as well. Hence the init function should init all the ports present in the detected controller (which could be 4 or 8). Signed-off-by: Narendra Sankar <nsankar@broadcom.com>
