Yes, I think the uart driver could be sufficient, but it has only the

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 
Digging into that now.
