[SCSI] aic94xx: update BIOS image from user space.
1. Create a file "update_bios" in sysfs to allow user to update bios
from user space.
2. The BIOS image file can be downloaded from web site
"http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300"
and copy the BIOS image into /lib/firmware folder.
3. The aic994xx will accept "update bios_file" and "verify bios_file"
commands to perform update and verify BIOS image .
For example:
Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios"
to update BIOS image from /lib/firmware/as483c01.ufi file into
HBA's flash memory.
Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios"
to verify BIOS image between /lib/firmware/asc48c01.ufi file
and
HBA's flash memory.
4. Type "cat /sys/devices/.../update_bios" to view the status or
result
of updating BIOS.
