THE FOLLOWING NOTES APPLY ONCE THE YOCTO LINUX IMAGE IS BUILT AND ROOTFS IS POPULATED:
======================================================================================
Use "murata-master" sub-folder for module-specific Bluetooth patchfiles. When executing "hciattach" in Linux, the BlueZ stack queries
the BT core for a chip ID (over UART connection) which it uses for loading the corresponding Bluetoothpatchfile from "/etc/firmware" folder.
The hcd files are renamed from CYW43XX to BCM43XX.
Files in sub-folder "murata-master" will have symbol "_" infront of the file name.
Ex: BCM43430A1.1DX.hcd will be named as _BCM43430A1.1DX.hcd
User will have to remove "_" and copy it to /etc/firmware.
NOTE: this Bluetooth patchfiles (*.hcd) are intended as reference only. The user needs to customize the Bluetooth patchfile to meet their HW/SW system requirements.
