Tegra doesn't enable ARM_AMBA and Tegra doesn't use the following
"drivers/amba/bus.c" right now. I needed to make this directory
available to ones without ARM_AMBA enabled.

Ah, right. I looked at arch/arm/Kconfig earlier to see if
tegra enabled ARM_AMBA but was accidentally looking
at ARCH_INtegraTOR when grepping for TEGRA ;-)

Your proposed solution sounds good then.

Thank you for reviewing patches & ACK. Attached the update one here,
instead of sending a while series again.

Subject: [PATCHv5 1/3] ARM: tegra: Add Tegra AHB driver

Tegra AHB Bus conforms to the AMBA Specification (Rev 2.0) Advanced
High-performance Bus (AHB) architecture.

The AHB Arbiter controls AHB bus master arbitration. This effectively
forms a second level of arbitration for access to the memory
controller through the AHB Slave Memory device. The AHB pre-fetch
logic can be configured to enhance performance for devices doing
sequential access. Each AHB master is assigned to either the high or
low priority bin. Both Tegra20/30 have this AHB bus.

Some of configuration params could be passed from DT too if needed.

What nonsense is this?  Please never put that in a patch you want
accepted upstream, as it makes no sense and we just have to edit it out
by hand, making us grumpy...

Sorry, my bad.

Stephen, would you mind removing that line when you take them in?
