If you can figure out the hardware (including processor/GPIO pins/flash/etc...), you can try building a Linux kernel for it. Once you get a working Linux kernel (with Android patches), you still need to find a way to enter some recovery/bootloader modes in order to flash it. If you don't need kernel changes, you can probably ignore them, but first make a backup of the system partition. You can also extract many device-specific information from the initramfs so also backup the ramdisk. You can usually find some init.*.rc files under the root directory, which are also device-specific information (usually except init.goldfish.rc). You can then try to compile a "vanilla" AOSP and try to flash it to the device, but probably many hardware will not work. You will need to work them out yourself.
I've once tried to port Android 2.3.7 to a device (which was originally Windows Mobile), the device can function, but some drivers are missing so functionality is restricted.
