+*****************************************************************************
+** ChibiOS/RT port for ARM-Cortex-M3 STM32F103.                            **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Olimex STM32-P103 board.
+
+** The Demo **
+
+This demo shows how to integrate the FatFs file system and use the SPI and MMC
+drivers.
+The demo flashes the board LED using a thread and monitors the MMC slot for
+a card insertion. When a card is inserted then the file system is mounted
+and the LED flashes faster.
+A command line shell is spawned on SD2, all the interaction with the demo is
+performed using the command shell, type "help" for a list of the available
+commands.
+
+** Build Procedure **
+
+The demo has been tested by using the free Codesourcery GCC-based toolchain,
+YAGARTO and an experimental WinARM build including GCC 4.3.0.
+Just modify the TRGT line in the makefile in order to use different GCC ports.
+
+** Notes **
+
+Some files used by the demo are not part of ChibiOS/RT but are copyright of
+ST Microelectronics and are licensed under a different license.
+Also note that not all the files present in the ST library are distributed
+with ChibiOS/RT, you can find the whole library on the ST web site:
