watchdog base addresses with dynamic address lookup\nfrom device tree for i.MX7ULP, i.MX8ULP, i.MX91, i.MX93, i.MX943, i.MX95\nand i.MX952.\n\nMove i.MX7ULP watchdog initialization from s_init() to\narch_cpu_init() because ofnode_* APIs depend on FDT, which is not\navailable during s_init().\n\nSigned-off-by: Alice Guo <alice.guo@nxp.com>\n---\n arch/arm/mach-imx/imx8ulp/soc.c | 14
