Posilam k patchi komentare a zaroven zkousim, jestli ten patch projde pres rtime (proto nemazu zbytecne casti).

Added new mach lpc17cmsis, successfully added some libs from CMSIS

Myslim, ze by se sluselo v komentari ke commitu uvest jakou verzi CMSIS jsi naimportovat a odkud jsi ji stahl a jestli jsi ji nejak menil nebo jsou to original zdrojaky. Taky by asi bylo lepsi neposilat to vsechno v jednom obrovskem patchi, ale rozdelit to na vic patchu a poradne je okomentovat - napriklad co radka v tomto komentari, to jeden patch.

Added new board for mbed development kit

Tady by zase bylo dobry vedet o jakou desku se presne jedna.

Added app for test mbed_led blink

Ta aplikace se jmenuje mbed_blink a ne bled_led.

Added cmsis-test which send out 0xAA to UART3 and send some dummy message to CAN2 at 125kbit

TODO: * exclude board config file from mach

Jakej config file mas na myslis? Ja v patchi zadnej nevidim. A kdyby tam byl, tak proc ho rovnou neodstranis?

* add more libs from CMSIS * support direct loading app to microprocessor --- app/arm/cmsis-test/Makefile | 14 + app/arm/cmsis-test/Makefile.omk | 20 + app/arm/cmsis-test/main.c | 152 ++ app/arm/mbed_blink/Makefile | 14 + app/arm/mbed_blink/Makefile.omk | 19 + app/arm/mbed_blink/main.c | 31 +

Zacinam prestavat mit rad adresar app. Vyhledove si myslim, ze by bylo rozumny davat testovaci aplikace do adresare k desce nebo k mach. Zatim to ale tady nech. Proberu to s Pavlem P. a pak to kdyztak presuneme sami.
