LPC2148的USB口固件升级代码

# =============================================================================
#
# Make file for USB Firmware Upgrader
#
# Processor: LPC214x (LPC2146)
#
# Output:    usb_fwu
#
# Compiler: GCC ARM  3.4.3 (GNUARM + Cygwin) or 4.10
#
# !!!! Do not use  GCC ARM 4.0.1. It makes a few problems  !!!!
#
#  No dependencies support. Call 'make clean' and than 'make' to rebuild all
