Yes, I think the uart driver could be sufficient, but it has only the Xilinx uart, the pl011 and the Xen emergency console. If I recall correctly, Renesas needs a different driver. Any platform specific initialization would also need to be added to it.
Actually the console driver (putchar) is really trivial in TBM, and for platform initialization I rely on u-boot's remainings. But I faced a strange issue with a timer interrupt. Despite the fact the TBM sets MMU, exception handlers table and VBAR, the interrupt does not cause TBMs code being called. But I see the interrupt fired and become active in GIC registers. Digging into that now.
