Message-Id: <200612010959.kB19xmAw002464@alkaid.it.uu.se>

Subject: [PATCH 2.6.19 3/3] sata_promise: cleanups
This patch performs two simple cleanups of sata_promise.
* Remove board_20771 and map device id 0x3577 to board_2057x.
After the recent corrections for SATAII chips, board_20771 and
board_2057x were equivalent in the driver.
* Remove hp->hotplug_offset and use hp->flags & PDC_FLAG_GEN_II
to compute hotplug_offset in pdc_host_init().
This patch depends on the sata_promise SATAII updates
patch I sent recently.
