> Unlike other SoC platforms, rockchip platforms doesn't require a binary
> generation on TF-A project.
> This is due to rockchip platforms have non-continuous memory areas in
> the linker script with a huge gap between them, so generating the binary
> would require addition padding which indeed increases the size of the binary.
> Interestingly this binary generation is disabled in v2.2 of TF-A on below
> commit:
>  commit <33218d2a8143> "rockchip: Disable binary generation for all SoCs."
> So, select default binary boot images as *.bin only if it's not rk3399.
> This fixes the atf build on rk3399 with v2.2.
> Note: the same can be applied to rest of rockchip platforms if
> they use v2.2 TF-A.

IIUC, it should be customized in your board defconfig.
