> The configuration options are similar to uboot package - once

No need for this 'Change-Id' because it means nothing to us.

I think I would prefer that we have a choice selection, like for U-Boot
for example:

    choice
        bool "mv-ddr-marvell version"

    config BR2_TARGET_MV_DDR_MARVELL_MARVELL
        bool "Marvell github" # Maybe get a better prompt here?

    config BR2_TARGET_MV_DDR_MARVELL_CUSTOM_GIT
        bool "Custom Git repository"

    endchoice

    if BR2_TARGET_MV_DDR_MARVELL_CUSTOM_GIT

    config BR2_TARGET_MV_DDR_MARVELL_CUSTOM_REPO_URL
        string "URL of custom repository"

    config BR2_TARGET_MV_DDR_MARVELL_CUSTOM_REPO_VERSION
        string "Custom repository version"

    endif # BR2_TARGET_MV_DDR_MARVELL_CUSTOM_GIT

Otherwise, we usually frown upon adding custom location to packages. Is
it customary for board integrators to have local adaptations to this,
like there is for u-boot and the other bootloaders?

As I see you're an @marvell.com, do you need that to use an internal
repository during development? If so, then why can't you just use the
OVERRIDE_SRCDIR mechanism instead?

Yann E. MORIN.
