soc/tegra: cbb: Add CBB 1.0 driver for Tegra194

Browse source

Adding driver to handle errors from Control Backbone (CBB) which are
generated due to illegal accesses. CBB 1.0 is used in Tegra194 SoCs.
When an error is reported from a NOC within CBB, the driver prints debug
information about failed transaction like Error Code, Error Description,
Master, Address, AXI ID, Cache, Protection, Security Group etc. It then
causes system crash using BUG_ON() or call WARN() based on whether the
error type is fatal or not.
