82169065ff memory: tegra: Add MC error logging support for Tegra264
In Tegra264, different components from memory subsystems like Memory
Controller Fabric (MCF), HUB, HUB Common (HUBC), Side Band Shim (SBS)
and channels have different interrupt lines for receiving memory
controller error interrupts.

Add support for logging memory controller errors reported by these
memory subsystems on Tegra264 by:
- Renaming tegra_mc_error_names array to tegra20_mc_error_names
  because it has a different bit index for error names compared to
  Tegra264.
- Defining the intmask registers and mask values supported for
  Tegra264.
- Registering interrupt handlers for interrupts associated with these
  different MC components which read the interrupt status registers to
  determine the type of violation that occurred.

9f26145109 memory: tegra: Prepare for supporting multiple intmask registers
Add a new structure for the intmask register e.g. MC_INTMASK_0 and
it's mask value. Add an array of these new structures to prepare for
supporting multiple intmask registers. This is done in preparation for
adding support for Tegra264 which supports multiple intmask registers.

2401dc4dcd memory: tegra: Add Tegra264 MC and EMC support
Add support to enable Memory Controller (MC) and External Memory
Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are
mostly the same as Tegra234 but differ in number of channels and
interrupt numbers.

The patch also adds the bandwidth manager definitions required for
Tegra264 and uses them to populate the memory client table. All of
these are needed to properly enable memory interconnect (ICC) support.
