#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/05/29 [EMAIL PROTECTED] 1.592.2.1
# USB OHCI driver: Added SA1111 support
#
# Added the patch from Russell King <[EMAIL PROTECTED]> that splits
# the usb-ohci driver into two pieces, enabling the sa1111 hardware to
# work with the driver.
#
# I also added some changes to get the usb-ohci-pci.o module to build
# and run properly.
