p.s. in the newer kernel, i have the config choices of SERIAL_TSUART
that didn't appear in the older kernel config. is that siginficant?

#
# Character devices
#
CONFIG_VT=y
CONFIG_VT_CONSOLE=y
CONFIG_HW_CONSOLE=y
# CONFIG_VT_HW_CONSOLE_BINDING is not set
# CONFIG_SERIAL_NONSTANDARD is not set
#
# Serial drivers
#
CONFIG_SERIAL_TSUART=y
# CONFIG_SERIAL_TSUART_7800 is not set
# CONFIG_SERIAL_8250 is not set
#
# Non-8250 serial port support
#
CONFIG_SERIAL_AMBA_PL010=y
CONFIG_SERIAL_AMBA_PL010_CONSOLE=y
# CONFIG_SERIAL_AMBA_PL011 is not set
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_UNIX98_PTYS=y
# CONFIG_LEGACY_PTYS is not set
