[RESEND v2 PATCH 00/16] Nokia RX-51: Fix USB TTY console and enable it

[Lukasz Majewski]

Hi Pali,

>     Resended v2 patch series with fixed commit messages
> 
> This patch series fix usbtty code (serial console via USB peripheral
> mode), fix underlying musb peripheral code, fix compilation of
> CONFIG_USB_DEVICE (used by usbtty), remove unused Nokia RX-51 code to
> decrease size of U-Boot binary and finally enable usbtty serial
> console for Nokia RX-51.
> 
> With this patch series debugging of Nokia RX-51 can be done also via
> USB serial console.
> 
> It fixes also stability of musb code and allows usage of file
> transfers via Kermit protocol on Nokia RX-51. Kermit file transfer
> via U-Boot loadb command is stable on Nokia N900 and gives about
> 52kB/s transfer rate.
> 
> On computer this serial console is accessible via /dev/ttyACM0 device.

I've integrated your patchset and now it turns out that the u-boot size
is too big:
