Virtualizetion of the whole BallDomain

[Mikemy666]

Finish the Virtualization of the whole BallDomain. The ToPhysicaline is applied in fronot of the Controller.scala module

[Copilot]

Pull request overview

This PR completes the virtualization of the BallDomain by relocating the ToPhysicalLine module from the BBus to the MemDomain, positioning it in front of the MemController. This architectural change unifies the memory interface using SramReadWithInfo and SramWriteWithInfo bundles that carry additional metadata (rob_id, is_acc, bank_id) through the system.

Key Changes:

• Moved ToPhysicalLine instantiation from BBus to MemDomain for better separation of concerns
• Updated BallDomain and BBus interfaces to use unified SramReadWithInfo/SramWriteWithInfo bundles instead of separate SRAM/ACC interfaces
• Removed obsolete accRead and accWrite connections throughout the hierarchy

Consider removing this commented-out code. The ToPhysicalLine module has been moved to MemDomain as part of this PR, so these commented lines serve no purpose and clutter the codebase.

Suggested change

	// val toPhysicalLines = Module(new ToPhysicalLine()(b, p))
	// toPhysicalLines.io.sramRead_i <> memoryrouter.io.sramRead_o
	// toPhysicalLines.io.sramWrite_i <> memoryrouter.io.sramWrite_o

Consider removing this commented-out code for accRead and accWrite. Since the virtualization now uses unified numBanks interfaces, these old separate accumulator interfaces are obsolete and keeping them commented out may cause confusion.

Suggested change

	// val accRead = Vec(b.acc_banks, Flipped(new SramReadIO(b.acc_bank_entries, b.acc_w)))
	// val accWrite = Vec(b.acc_banks, Flipped(new SramWriteIO(b.acc_bank_entries, b.acc_w, b.acc_mask_len)))

The comment has a spelling error: "ToPhysical" should be "ToPhysicalLine" for clarity and consistency with the module name.

Suggested change

	// ToPhysical interface
	// ToPhysicalLine interface

[Copilot]

The ToPhysicalLine import is no longer used in this file since the ToPhysicalLine module instantiation has been removed and moved to MemDomain. Consider removing this unused import to keep the code clean.

Suggested change

	import framework.switcher.{ToPhysicalLine, ToVirtualLine}
	import framework.switcher.ToVirtualLine
