Porting Android to an ARM platform a new bee question

[Sachin Naik]

Hello All,
        I am planning to port android on to an ARM9 platform.
        I have following questions:
        1. Where can I get the Linux kernel source code for Android?
        2. Is ARM9 sufficient to run the complete system or does it need more powerful processor?
        3. What are the RAM and ROM requirements?
        4.If I happened to develop a driver for any of the peripherals  where  should I publish the code?

Thanks in advance

1. look at http://git.android.com/, or download the tarball from http://code.google.com/p/android/downloads/list

2. ARM9 is sufficient (ARM5TE is the minimum, CPU wise), but there are many other details regarding the rest of the hardware where I can't give any good answer

3. don't know exactly, the emulator uses 96MB Ram, but you can probably test the system with less memory (e.g. use '-qemu -m 64' for 64MB). and the system images must be about 64MB of Flash. that doesn't mean these are the minimum, just that the current system runs on them (the final system may require more, can't tell)

4. You would publish it through a public git repository of your modified kernel code, which would allow anyone to diff/compare/merge it in their own kernel tree.

happy hacking !
