These files come from the RealtekBluetoothUartPackage_2.17.119.0525 file
which can be downloaded from realtek.com. The download is marked as version
1.0.245.3 / 05/08/2017 on the download page.
The added rtl_bt/rtl8723bs_fw.bin file is called
rtl8723b_mp_bt40_fw_asic_rom_patch.bin in the download.
The added rtl_bt/rtl8723bs_config-OBDA8723.bin file is the
rtl8723b_config_internal.bin file with the UART baudrate changed to
1500000 bps.
I've examined aprox. 20 different Intel BYT/CHT boards, with an RTL8723BS
with the OBDA8723 ACPI ID for the bluetooth part. On these boards the
original firmware image uses either 1500000 or 3000000 bps, so 1500000 bps
is chosen as the safe option which should work everywhere.
