[HELP-OMAP-SERAIL] Add 2.6.37 high-speed UART driver to 2.6.32

Hi, 

I am running Android Ecalir on Devkit8000 board OMAP3530.

The kernel I used was git from 0xdroid branch omap3-2.6.32.

My goal is getting higher UART baud rate(3M).

I found the patch “serial: Add OMAP high-speed UART driver”. http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=commitdiff;h=b612633b5928077441b979471869753bfa93d41a

I followed the patch to add the 2.6.37 omap-serial driver (omap-serial.c, omap-serial.h,etc.) to 2.6.32 kernel.

Because 2.6.32 serial.c doesn’t mention about “CONFIG _SERIAL_OMAP”, so I also replaced it with 2.6.37 serial.c.

Problem: I can’t use UART1 and UART3 to communicate with PC now.

Even the bootargs is “console=ttyS2,115200n8” or “console=ttyO2,115200n8”, there is no boot information on console.

=====================================================================

The message stopped at :

Starting kernel ...

Uncompressing Linux............................................................................................................................................................................... done, booting the kernel.

=====================================================================

After booting, it can enter android filesystem successfully.

There is /dev/ttyS*, but there is no /dev/ttyO*.

Then I disabled the new driver CONFIG _SERIAL_OMAP and used 8250, but the result is the same.

Is it because I missed to modify any related files when I replaced 2.6.32 serial.c with 2.6.37 version? (For example, changing omap_hwmod_34xx.h to omap_hwmod_3xxx.c)

Any idea to add the 2.6.37 omap-serial driver to 2.6.32 kernel or get /dev/ttyO* on 2.6.32?

Thanks for your help.
