In Multi DDR subystems with interleaving support, the following needs to
configured,
- interleaving granular size and region
- EMIFs to be enabled
- EMIFs with ecc to be enabled
- EMIF separated or interleaved
- number of cycles of unsuccessful EMIF arbitration to wait before
arbitrating for a different EMIF port, by default set to 3
Add support for configuring all the above by using a MSMC device

ram: k3-ddrss: Add support for multiple instances of DDR subsystems2022-02-08T14:41:26ZAswath Govindrajua-govindraju@ti.com2022-01-25T15:26:29Zurn:sha1:1a99bec018f5aec6aee77d36e222423e99bbd6a3
The current driver only supports single instance of DRR subsystem. Add
support for probing multiple instances of DDR subsystem.

Add a pointer to ddr instance int the lpddr4_privatedata_s structure for
supporting mutliple instances of DDR in the drivers.

Attempt to get and enable a vtt regulator if one is provided from the
dts. If we do not find one, continue as not all platforms have this.

ram: k3-ddrss: Introduce support for AM642 SoCs2021-05-12T11:00:52ZDave Gerlachd-gerlach@ti.com2021-05-11T15:22:12Zurn:sha1:9f9b5c1c16ddbb0a3a42e0424887d9cad34d89f4
Introduce support for the AM64 DDRSS controller which uses the 16bit
variation of the controller. This controller shares much functionality
with the existing J721e support, so this patch introduces only the new
code needed for am64 specific support from "_16bit_" files with headers
under "16bit/" include path/.
Also add a CONFIG_K3_AM64_DDRSS option to the choice required for use
with CONFIG_K3_DDRSS to allow selecting AM64 support.

ram: k3-ddrss: Introduce common driver with J7 SoC support2021-05-12T11:00:52ZDave Gerlachd-gerlach@ti.com2021-05-11T15:22:11Zurn:sha1:a8c13c777e88db7af019fa00aaaa030a1ee3b8d9
Introduce a new version of the ddr driver which has the ability to
support different variations of the controller. Also introduce support
for the 32bit variation of the controller which is what was already
supported by the previous version used for J721e and J7200.

Rename the k3-j721e folder under drivers/ram to k3-ddrss in preparation
of introducing additional support for other platforms to the same
driver.
