# This python script generates the "arch_info.bin" file required by the ALMOS-MK
# operating system bootloader and describing the target hardware architecture.
# It uses an architecture specific, python script that must be called "arch_info.py".
#
# The source directory containing the "arch_info.py" file and the destination directory
# to store the "arch_info.bin" file are defined by parameters on the command line:
#  --arch=string     : path to directory containing the "arch_info.py" file
#  --bin=string      : path to directory store the "arch_info.bin" file
#
# As the target architecture is generic, the following hardware parameters can be
# defined on the command line:
#  --x_size=int      : number of clusters in a row
#  --y_size=int      : number of clusters in a column
#  --nb_cores=int    : number of cores per cluster
#  --nb_ttys=int     : number of TTY channels 
#  --nb_nics=int     : number of NIC channels 
#  --fbf_size=int    : frame buffer width & heigth
#  --ioc_type=string : can be IOC_BDV , IOC_HBA , IOC_SDC , IOC_SPI
#
# The following parameters can be used to generate the optional "hard_config.h" file,
# that is required to configurate the SystemC virtual prototype, and the "arch_info.xml" 
# file for debug.
#  --hard=string     : path to directory to store the "hard_config.h" file
#  --xml=string      : path to directory to store the "arch_info.xml" file
