Function Documentation

memc_tt_mimir_set_config()

int memc_tt_mimir_set_config	(	const struct device *	dev,
		const gddr_backend_t *	backend,
		fw_params_t *	params )

Install the platform GDDR configuration for the controller.

Stores the backend and fw_params in the device's data; the device passes them to gddr_init() at its own init. Call once, before the memc device initializes.

The backend and fw_params are runtime/platform-supplied (host-written params, environment-selected backend), which is why they arrive through this API rather than devicetree. params is non-const because this call fills in gddr_tile_mask from the controller's own DT topology (the mem-tiles).

Parameters

dev	The memc controller device.
backend	Caller-owned backend (non-NULL, with a non-NULL get_blob).
params	fw_params minus gddr_tile_mask

Returns

0 on success, -EINVAL if dev, backend, backend->get_blob, or params is NULL.
