Wesley W. Terpstra 7ee79efc15 Merge pull request #333 from ucb-bar/tl2-api-changes 
Tl2 api changes
 2016-09-22 21:20:27 -07:00
Wesley W. Terpstra c5706afc11 RegField: remove obsolete split method 
This is now natively supported by the regmap(...) invocation.
 2016-09-22 20:52:47 -07:00
Wesley W. Terpstra fc44151f10 RegField: add name and description fields 
In the future we can generate interesting documentation and headers.

Wesley W. Terpstra 5e34b313ee RegMapper: regmap(...) now takes BYTE addresses 
If a device has configurable bus-width, we need a stable way of
enumerating registers. The byte offset stays unchanged.

This change also makes it possible to put an arbitrary number of RegFields
starting at some address which are then chopped up into appropriately bus-
sized registers.

Wesley W. Terpstra 972ca06729 RegField: remove RegField.bytes; it was dangerous 
The implementation unconditionally drove the register.
This made it incompatible with drivers from the device itself.
Besides, writing only parts of a register at a time is ultra-shady.

Wesley W. Terpstra a421469754 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))))
