get_overlay_mmc variable has the following logic which is responsible to load overlays,

load mmc ${bootpart} ${dtboaddr} ${bootdir}/${overlay} 

The above logic should have be corrected to add dtb prefix as well in order to make the overlay applying logic in UEnv.txt via name_overlays consistent across all k3 platforms,

load mmc ${bootpart} ${dtboaddr} ${bootdir}/dtb/${overlay} 

so that uEnv.txt can use to apply overlays with `name_overlays=ti/<overlay>.dtbo` instead of  `name_overlays=dtb/ti/<overlay>.dtbo` (which isn't consistent across other platforms)

While doing this ensure that https://git.ti.com/cgit/ti-u-boot/ti-u-boot/commit/board/ti?h=ti-u-boot-2025.01&id=299d86af00f2a64e962ffcd45bd36dca1ed45649 commit is fixed as well to below,

name_overlays=ti/k3-am62a7-sk-edgeai.dtbo 

Note - This issue gets inherited from upstream u-boot which seems to be missing that `dtb` prefix in path - https://github.com/u-boot/u-boot/blob/master/board/ti/am62ax/am62ax.env#L26
