soc/cores/hyperbus: Full rewrite of HyperRAM core.
...
Rewriting the HyperRAM core to improve its design and functionality. The
old core grew complex over time without a clear structure. This new version
offers:
- IO registers on all signals for better performance.
- Flexible clocking options.
- Simplified architecture.
- Easier to extend with new features.
This rewrite provides a base for future development.

csr_bus: Honour re signal from the upstream bus
...
Currently CSR bus assumed that ~we means reading, that created
a problem that when for a CSR if reading has side effects and adr
parked unintentionally at that CSR, the reading side effect will be
triggered.
For SoCs, this happened when upstream bus issued a write transaction
with wishbone.sel, then on CSR bus it will be translated
as adr = addr, we = 0, which will be interpreted as a read to such
address, and trigger undesired side effect for such CSR.
Such upstream transaction will be generated by our bus width converter.
Given that we signal already presents in CSR Interface, the easiest way
to handle such situation is to generate re signal at bus bridges and
propagate it all the way down to the Interface.
