+NOTES
+=====
+The TLL56527M board contains analog devices blackfin 527 processor. In addition
+to the peripherals provided by bf527 the board has a temprature sensor, 
+accelerometer and power module connected via I2C. It also has LCD interface,
+Card reader interface.
+
+The analog device bf52X family of processors are different from the bf53x range 
+of processors. This port supports the additional features that are not 
+supported by the blackfin 53X family of processors.
+  
+The TLL6527M does not use the interrupt module used by the bfin 53x since it has
+an additional system interrupt controller isr registers for additional lines.
+On the 53X these line are multiplexed. 
+The centralized interrupt handler is implemented to use lookup tables for 
+jumping to the user ISR. For more details look at files implemented under 
+libcpu/bfin/bf52x/interrupt/*
+
+This port supports only the uart peripheral. The uart is supported via 
+polling, DMA, interrupt. The uart file is generic and is common between the 
+ports. Under bsp configure.ac files 
+* change the CONSOLE_BAUDRATE or to choose among different baudrate.
+* Set UART_USE_DMA for UART to use DMA based transfers. In DMA based transfer
+  chunk of buffer is transmitted at once and then an interrupt is generated.
+* Set CONSOLE_USE_INTERRUPTS to use interrupt based transfers. After every 
+  character is transmitted an interrupt is generated. 
+* If CONSOLE_USE_INTERRUPTS, UART_USE_DMA are both not set then the port uses
+  polling to transmit data over uart. This call is blocking. 
+
+TLL6527 specific file are mentioned below.
