+**  Description:   This program downloads a patchram files in the HCD format

+**				   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>

+**							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.
