The file arch/arm/mach-imx/Kconfig is unconditionally include, so this
will set SYS_MALLOC_F_LEN for other boards as well. What I have done
locally is to include a depends on with all sub-families with DM
support. If you want you can just use it or I can also submit it as
well.
config SYS_MALLOC_F_LEN
default 0x2000
depends on ARCH_IMX8 || ARCH_IMX8M || ARCH_MX7 || ARCH_MX7ULP || \
ARCH_MX6 || ARCH_MX5
Thanks,
Lukas
