1) BSP is provided in binary format on the web. With software license agreement you can get buildable modules. Source is only available for purchase.
2) I don't know the answer to that -- hopefully one of guys involved will respond.
3) The kit is provided with a bootloader called Lolo that will allow you to load any BSP or piece of code. It supports multiple file types (elf, raw, bin, srec, etc.) If you are developing a custom bootloader you can develop in RAM then use Lolo to burn your code into flash when complete.
4) This link answers the support questions:
