The mask of a Get should also be converted.
This manifested as a bug when going from 32=>64 bits. A large Get
could end up with mask that was not full.
* tilelink2 Edges: add accessor methods for address and addr_{hi,lo}
* tilelink2: use addr_lo instead of relying on truncation
Truncation can mess up if the width should be 0, but IS 1.
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))))
* tilelink2 Narrower: support widenening and narrowing on all channels
Be extra careful with the mask transformations
We need to make sure that narrowing or widening do not cause a loss
of information about the operation. The addr_hi+(mask|addr_lo) conversions
are now 1-1, except on D, which should not matter.
* tilelink2 SRAM: work around firrtl SeqMem bug
* tilelink2 WidthWidget: renamed from Narrower (it now converts both ways)
* tilelink2 mask: fix an issue with width=1 data buses
