+** Name: brcm_patchram_plus.c
+**
+** Description: This program downloads a patchram files in the HCD format
+** to Broadcom Bluetooth based silicon and combo chips and
+** and other utility functions.
+**
+** It can be invoked from the command line in the form
+** <-d> to print a debug log
+** <--patchram patchram_file>
+** <--baudrate baud_rate>
+** <--bd_addr bd_address>
+** <--enable_lpm>
+** <--enable_hci>
+** <--use_baudrate_for_download>
+** <--scopcm=sco_routing,pcm_interface_rate,frame_type,
+** sync_mode,clock_mode,lsb_first,fill_bits,
+** fill_method,fill_num,right_justify>
+**
+** Where
+**
+** sco_routing is 0 for PCM, 1 for Transport,
+** 2 for Codec and 3 for I2S,
+**
+** pcm_interface_rate is 0 for 128KBps, 1 for
+** 256 KBps, 2 for 512KBps, 3 for 1024KBps,
+** and 4 for 2048Kbps,
+**
+** frame_type is 0 for short and 1 for long,
+**
+** sync_mode is 0 for slave and 1 for master,
+**
+** clock_mode is 0 for slabe and 1 for master,
+**
+** lsb_first is 0 for false aand 1 for true,
+**
+** fill_bits is the value in decimal for unused bits,
+**
+** fill_method is 0 for 0's and 1 for 1's, 2 for
+** signed and 3 for programmable,
+**
+** fill_num is the number or bits to fill,
+**
+** right_justify is 0 for false and 1 for true
+**
+** <--i2s=i2s_enable,is_master,sample_rate,clock_rate>
+**
+** Where
+**
+** i2s_enable is 0 for disable and 1 for enable,
+**
+** is_master is 0 for slave and 1 for master,
+**
+** sample_rate is 0 for 8KHz, 1 for 16Khz and
+** 2 for 4 KHz,
+**
+** clock_rate is 0 for 128KHz, 1 for 256KHz, 3 for
+** 1024 KHz and 4 for 2048 KHz.
+**
+** <--no2bytes skips waiting for two byte confirmation
+** before starting patchram download. Newer chips
+** do not generate these two bytes.>
+** <--tosleep=number of microsseconds to sleep before
+** patchram download begins.>
+** uart_device_name
+**
+** For example:
+**
+** brcm_patchram_plus -d --patchram \
+** BCM2045B2_002.002.011.0348.0349.hcd /dev/ttyHS0
+**
+** It will return 0 for success and a number greater than 0
+** for any errors.
+**
+** For Android, this program invoked using a
+** "system(2)" call from the beginning of the bt_enable
+** function inside the file
+** system/bluetooth/bluedroid/bluetooth.c.
+**
+** If the Android system property "ro.bt.bcm_bdaddr_path" is
+** set, then the bd_addr will be read from this path.
+** This is overridden by --bd_addr on the command line.
