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...
