* a very very basic Common Data Bus infrastructure.
* a TLB and MMU are not strictly essential (not for a proof-of-concept ASIC)
* neither in some ways is a L1 cache
-* [[180nm_Oct2020/interfaces]] we need as a bare minimum include GPIO, EINT, SPI and QSPI,
- I2C, UART16550, LPC (from Raptor Engineering) and that actually might
- even be it.
