Subject: imx: ele_ahab: Implement display_life_cycle() for i.MX95
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=226a606c10de005d6fbffa07531ef2817ff6e933;p=thirdparty%2Fu-boot.git

imx: ele_ahab: Implement display_life_cycle() for i.MX95

The register reflects lifecycle and some lifecycle-derived state of
i.MX95 has new offset address and layout, so display_life_cycle() is
added specifically for it.
