This patch set is to add a subcommand 'release' to the 'cpu' command in cmd/cpu.c, making the command is able to release a core to run baremetal and RTOS applications.
And enabled the 'cpu' command and imx CPU driver for i.MX 8M series EVK boards and i.MX 93 EVK board.

Hou Zhiqiang (9): cpu: add release_core callback cpu: sandbox: implement release_core callback test: cpu: add test for release CPU core. cpu: imx: implement release_core callback cpu: imx: fix the CPU type field width cpu: imx: Add i.MX 8M series SoCs cmd: cpu: add release subcommand configs: imx8m: enable the 'cpu' command configs: imx93: enable the 'cpu' command
--- V2: - Implemented release_core() in sandbox and added test for the new API. - Increased the CPU type mask in i.MX CPU driver. - Added i.MX 8M series SoCs in i.MX CPU driver
