# [PNPBIOS] Move Parsing Functions to the PnPBIOS driver
#
# This patch moves the resource parsing functions from support.c to the
# pnpbios driver. Originally these functions were intended for other
# pnp protocols but in reality they are only used by the PnPBIOS driver.
# This patch greatly cleans up the code in both the parsing functions
# and their connection with the pnpbios driver. Also note that
# pnpbios.h has been added for local pnpbios functions.

# [PNP] Remove device naming based on id
#
# This patch removes the pnp name database code. Most buses, including
# pnp, will be using userspace to name devices in the near future. Also
# dev->name will be removed from the driver model soon.
