Oh, using hdlc-y even for CONFIG_HDLC=m. :)
OK, it's still not working. As Dave Jones reported:

Or enabling all SYNCLINK drivers =m with HDLC support:

with partial .config:
# CONFIG_WAN is not set
CONFIG_HDLC=m
# CONFIG_HDLC_RAW is not set
# CONFIG_HDLC_RAW_ETH is not set
# CONFIG_HDLC_CISCO is not set
# CONFIG_HDLC_FR is not set

CONFIG_SYNCLINK=m

CONFIG_SYNCLINKMP=m
CONFIG_SYNCLINKMP_HDLC=y
CONFIG_SYNCLINK_GT=m
CONFIG_SYNCLINK_GT_HDLC=y
CONFIG_N_HDLC=m
so the hdlc_generic code isn't available for some reason.
