Yes, 400M isn't enough. I can't believe it either. Change-Id: I7d3857f04bfda472af6a281017204672bb9c9940
The "generic" product defines a non-hardware-specific target without a kernel or bootloader. It can be used to build the entire user-level system, and will work with the emulator, though sound will not work (see the "emulator" product for that). It is not a product "base class"; no other products inherit from it or use it in any way.
