2021-06-23remoteproc: imx_rproc: support i.MX8ULPPeng Fan1-0/+13
i.MX8ULP is a new SoC with Ultra low power support, it has a Cortex-M33 core and two Cortex-A35 cores. We need to add new configuration because it could not reuse the previous i.MX7/8 configuration. i.MX8ULP M33 core is kicked by ROM, it is not under control of A35 core. So need to mark the method is IMX_RPROC_NONE.

2021-06-01remoteproc: imx_rproc: support i.MX7ULPPeng Fan1-11/+38
i.MX7ULP A7 core runs under control of M4 core, M4 core starts by ROM and powers most services used by A7 core, so A7 core has no power to start and stop M4 core. And the M4 core's state is default RPROC_DETACHED and remoteproc framework not able to stop the M4 core.

Add three methods IMX_RPROC_NONE(no need start/stop), IMX_RPROC_MMIO (start/stop through mmio) and IMX_RPROC_SMC(start/stop through ARM SMCCC).

2021-04-13remoteproc: imx_rproc: support remote cores booted before Linux KernelPeng Fan1-0/+45
- When remote cores are kicked before Linux Kernel, we are not able to get resource table from the firmware elf file, so we need to add rsc_table to hold the resource table published by remote cores and imx_rproc_get_loaded_rsc_table is to get the resource table. - Per remoteproc framework, add attach hook for processor in a detached state. - Add imx_rproc_detect_mode to detect remote cores' working mode to set the state which is required by remoteproc framework.
