#
# The driver major device number
# The new linux/Documentation/devices.txt defines major=91 for CAN
# This major number is used f黵 the internl CAN of the AT91SAM9263.
# The driver for the SPI MCP connected to the SSV ARM Board 
# is using 92. According to Documentation/devices.txt:
# 92 char        Reserved for ith Kommunikationstechnik MIC ISDN card
CAN_MAJOR=	92
CAN_MODULE = canspi.ko
TARGET=SSV_MCP2515
# location of the compiled objects and the final driver module
OBJDIR = obj

# Debugging Code within the driver
# to use the Debugging option
# and the Debugging control via /proc/sys/Can/DbgMask
# the Makefile in subdir Can must called with the DEBUG set to
# DEBUG=1
# else
# NODEBUG
# doesn't compile any debug code into the driver
DEBUG=NODEBUG
DEBUG=DEBUG=1

# all definitions for compiling the sources
# CAN_PORT_IO		- use port I/O instead of memory I/O
# CAN_INDEXED_PORT_IO   - CAN registers adressed by a pair of registers
#			  one is selcting the register the other one does i/O
#			  used eg. on Elan CPUs
# CAN4LINUX_PCI
# IODEBUG               - all register write accesses are logged
# CONFIG_TIME_MEASURE=1 - enable Time measurement at parallel port
#
# CAN_MAX_OPEN		- the driver can be opened more than once
#                         the number specifies the number of possible
#			  different process, the number of RX queues
#			  the driver has to handle
#
