tilelink2: Fragmenter should not cut Acquire parameters
...
The correct response to misuse is to fail a requirement check.
Pretending that things are not caches could lead to inconsistency.

[tilelink2] Add unit tests for many TL2 components

tilelink2: change adapters to use TLAdapter(params, defaults)(node)
...
This API makes it much more readable when you have multiple adapters
combined into a single line. The arguments for each adapter stay
beside the adapter.
For example, this:
peripheryBus.node := TLWidthWidget(TLBuffer(TLAtomicAutomata()(TLHintHandler(legacy.node))), legacy.tlDataBytes)
becomes this:
peripheryBus.node := TLWidthWidget(legacy.tlDataBytes)(TLBuffer()(TLAtomicAutomata()(TLHintHandler()(legacy.node))))
