Currently driver may end up caching disabled port ID as active interface. Fix this by bailing out earlier in case port is marked disabled in the DT. Signed-off-by: NVignesh Raghavendra <vigneshr@ti.com>

CPSW NUSS IP on K3 SoCs can have more than one external port (upto 8) Therefore increase AM65_CPSW_CPSWNU_MAX_PORTS to 9 (8 ext + 1 Root port) as preparation to allow any one of the 8 ports to be used as ethernet interface in U-Boot. Signed-off-by: NVignesh Raghavendra <vigneshr@ti.com>

ICSSG Ethernet driver uses two src threads per port (one per slice). Similarly CPSW uses one src thread. Drop PSIL EP static data for other src threads in order to reduce R5 SPL footprint. This makes AM65x board bootable again. Signed-off-by: NVignesh Raghavendra <vigneshr@ti.com>

With AM64x supporting only K3_NAV_RINGACC_RING_MODE_RING or the exposed ring mode, all other K3 SoCs have also been moved to this common baseline. Therefore drop other modes such as K3_NAV_RINGACC_RING_MODE_MESSAGE (and proxy) to save on SPL footprint. There is a saving of ~800 bytes with this change for am65x_evm_r5_defconfig.

AM64 dual mode rings are modeled as pair of Rings objects which has common configuration and memory buffer, but separate real-time control register sets for each direction mem2dev (forward) and dev2mem (reverse). AM64 rings must be requested only using k3_ringacc_request_rings_pair(), and forward ring must always be initialized/configured. After this any other Ringacc APIs can be used without any callers changes. Signed-off-by: NVignesh Raghavendra <vigneshr@ti.com>

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. Signed-off-by: NDave Gerlach <d-gerlach@ti.com>
