- Change NANDFlash again for Versatile support. Now the LLB and OS Loader are created...

- Now the only complication is that RAMDISK loaded at 0x80000 which will conflict with the 0x800000 range where kernel loads. Could move RAMDISK in code through LLB, but that would be very expensive (shift by 16MB up). Instead, NANDflash creates ramdisk image starting at offset 16MB. This way, emulator thinks it's loading at 0x80000, but actually loads at 0x1800000. Would be better if QEMU not hardcoded the INITRD_LOAD_ADDR...
