[PATCH v5 3/6] arm: mediatek: build Genio 510 and 700 boot images with binman

Carlo Caione <[email protected]>
Newsgroups org.u-boot-project.lists.u-boot
Message-ID <20260827-ccaione-upstream-mt8390-spl-v5-3-81d04e3ab785@baylibre.com> 
Genio 510 and Genio 700 use an external DDR loader before U-Boot SPL,
then load the remaining firmware from a FIT. Add shared binman
descriptions for both images so integration builds can assemble the
complete boot chain.

Keep packaging optional because the required platform firmware is built
outside U-Boot.
