imx7: Disable CAAM Job Ring 0 Trying to boot a fitImage after a successful hab_auth_img operation causes the following error: ## Loading kernel from FIT Image at 88000000 ...

The reason for this error is that the BootROM uses the CAAM Job Ring 0, so disable its node in U-Boot to avoid the resource conflict. imx8m dtsi files also have the Job Ring 0 disable since the following kernel commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch?h=v6.5&id=dc9c1ceb555ff661e6fc1081434600771f29657c For a temporary solution, disable the Job Ring 0 in imx7s-u-boot.dtsi.

smegw01: Convert to watchdog driver model Commit 68dcbdd594d4 ("ARM: imx: Add weak default reset_cpu()") caused the 'reset' command in U-Boot to not cause a board reset. Fix it by switching to the watchdog driver model via sysreset, which is the preferred method for implementing the watchdog reset.
