It's never been legal to mix implicit and explicit (normal) rules.
However, older versions of make didn't always catch these problems; if
you started with a pattern target then had non-pattern targets later, it
would fail.  If you started with non-pattern targets and had pattern
targets later, it would succeed.  The newest version is consistent: you
can't mix them regardless of the order they appear in.

Even though it didn't give an error, the makefile you had didn't work as
you expected it to.  Make would create a pattern rule like this:

        zImage% dtbImage% treeImage.% cuImage.% simpleImage.%:

which doesn't do what I'm pretty sure you meant; see the GNU make
manual, section on multiple patterns in a pattern rule.
