The i.MX8M boards use partially specified binman images which have an SPL entry without a U-Boot entry. This would normally cause an error due to the 'u_boot_any' binman symbols declared by BINMAN_UBOOT_SYMBOLS requiring a U-Boot-like entry in the same image as the SPL.
However, a problem in the ARMv8 __image_copy_start symbol definition effectively disables binman from attempting to write any symbols at all, so everything appears to work fine until runtime. A future patch fixes the issue in the linker scripts, which lets binman fill in the symbols, which would result in the build error described above.
Explicitly disable the 'u_boot_any' symbols for i.MX8M boards. They are already effectively unusable, and they are incompatible with the boards' current binman image descriptions.
