/*
* eata.c - Low-level driver for EATA/DMA SCSI host adapters.
*
+ * 20 Feb 2002 Rev. 7.22 for linux 2.5.5
+ * + Remove any reference to virt_to_bus().
+ * + Fix pio hang while detecting multiple HBAs.
+ * + Fixed a board detection bug: in a system with
+ * multiple ISA/EISA boards, all but the first one
+ * were erroneously detected as PCI.
+ *
* 01 Jan 2002 Rev. 7.20 for linux 2.5.1
* + Use the dynamic DMA mapping API.
*
* boot time.
* + Improved boot messages: all tagged capable device are
* indicated as "tagged" or "soft-tagged" :
- * - "soft-tagged" means that the driver is trying to do its
+ * - "soft-tagged" means that the driver is trying to do its
* own tagging (i.e. the tc:y option is in effect);
* - "tagged" means that the device supports tagged commands,
* but the driver lets the HBA be responsible for tagging
* + When loaded as a module, accepts the new parameter boot_options
* which value is a string with the same format of the kernel boot
* command line options. A valid example is:
- * modprobe eata boot_options=\"0x7410,0x230,lc:y,tc:n,mq:4\"
+ * modprobe eata 'boot_options="0x7410,0x230,lc:y,tc:n,mq:4"'
*
* 9 Sep 1999 Rev. 5.10 for linux 2.2.12 and 2.3.17
* + 64bit cleanup for Linux/Alpha platform support
* the driver sets host->wish_block = TRUE for all ISA boards.
