# DAHDI_SPI_INTERFACE with DAHDI_GSM_MODULE currently not supported.
# http://www.ucpbx.com/files/file/GSM1_User_Manual.pdf
#
# Choose just one (1) of the lines below:
#   DAHDI_SPI_INTERFACE uses the Blackfin SPI hardware to talk
#   to the analog modules. This method is used for the earlier IP04s
#   and all IP04s shipped by Rowetel. Unfortunately it means the MMC
#   card can't be used, as dahdi hogs the SPI bus!
#
#   DAHDI_SPORT_INTERFACE uses the SPORT1 hardware to implement
#   a SPI port to talk to the analog modules.  This fees up the SPI
#   bus for the MMC card. This was developed by Alex Tao (thanks Alex)
#   and is likely to be the standard for the future.
#
# Note that different CPLD firmware is required to support each SPI
# method, if your IP04 won't detect modules this is a sign you may
# have the wrong CPLD firmware and/or driver.
