/* All GDT Disk Array Controllers are fully supported by this driver.
* This includes the PCI/EISA/ISA SCSI Disk Array Controllers and the
* PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete
* list of all controller types.
*
* If you have one or more GDT3000/3020 EISA controllers with
* controller BIOS disabled, you have to set the IRQ values with the
* command line option "gdth=irq1,irq2,...", where the irq1,irq2,... are
* the IRQ values for the EISA controllers.
*
* After the optional list of IRQ values, other possible
* command line options are:
* disable:Y disable driver
* disable:N enable driver
* reserve_mode:0 reserve no drives for the raw service
* reserve_mode:1 reserve all not init., removable drives
* reserve_mode:2 reserve all not init. drives
* reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with
* h- controller no., b- channel no.,
* t- target ID, l- LUN
* reverse_scan:Y reverse scan order for PCI controllers
* reverse_scan:N scan PCI controllers like BIOS
* max_ids:x x - target ID count per channel (1..MAXID)
* rescan:Y rescan all channels/IDs
* rescan:N use all devices found until now
* hdr_channel:x x - number of virtual bus for host drives
* shared_access:Y disable driver reserve/release protocol to
* access a shared resource from several nodes,
* appropriate controller firmware required
* shared_access:N enable driver reserve/release protocol
* probe_eisa_isa:Y scan for EISA/ISA controllers
* probe_eisa_isa:N do not scan for EISA/ISA controllers
* force_dma32:Y use only 32 bit DMA mode
* force_dma32:N use 64 bit DMA mode, if supported
*
* The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N,
* max_ids:127,rescan:N,hdr_channel:0,
* shared_access:Y,probe_eisa_isa:N,force_dma32:N".
* Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y".
*
* When loading the gdth driver as a module, the same options are available.
* You can set the IRQs with "IRQ=...". However, the syntax to specify the
* options changes slightly. You must replace all ',' between options
* with ' ' and all ':' with '=' and you must use
* '1' in place of 'Y' and '0' in place of 'N'.
*
* Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0
* max_ids=127 rescan=0 hdr_channel=0 shared_access=0
* probe_eisa_isa=0 force_dma32=0"
* The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1".
