-Win32-MSVS - ChibiOS/RT simulator and demo into a WIN32 process,

-ARM7-LPC214x-GCC - ChibiOS/RT port for ARM7 LPC2148, the demo targets the
- Olimex LPC-P2148 board. This port can be easily modified
- for any processor into the LPC2000 family or other

*** Releases ***
*****************************************************************************
+*** 0.4.3 ***
+- Minor improvement in the LPC214x serial driver, unneeded events were
+ generated.
+- Size optimization in the events code, now the chEvtWait() reuses the
+ chEvtWaitTimeout() code if it is enabled.
+- Size optimization in the semaphores code, now the chSemWaitTimeout() just
+ invokes the chSemWaitTimeoutS() inside its system mutex zone.
+- Fixed a chSysInit() documentation error.
+
*** 0.4.2 ***
- Added a minimal ARM7-LPC demo, you can use this one as template in order to
create your application. It is easier to add subsystems back to the small
