From 042c21fd2c3aa553907020131caa553a9da24589 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 9 Oct 2005 09:35:46 -0400 Subject: [PATCH] [libata sata_sil24] add support for 3131/3531 This patch adds support for sil_3131 and sil_3531. Both are identical to 3124 except that they have only one port. Bits 30 and 31 of ata_port_info->host_flags is used to encode available port numbers. Version number is bumped to 0.22. Edward Falk supplied all the necessary information and preliminary patch.
