Applied to target-arm.next, thanks. -- PMM

Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices. This allows operating systems such as Linux to run emulations such as mcimx6ul-evk. Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected memory ranges were covered by the unimplemented DAP device. The commit reduced the DAP address range from 0x100000 to 4kB, and the emulation thus no longer covered the various unimplemented devices in the affected address range. Fixes: 0cd4926b85 ("Refactor i.MX6UL processor code") Cc: Jean-Christophe Dubois <jcd@tribudubois.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- This patch is necessary to boot mcimx6ul-evk with Linux v6.7.
