[meta-ti,master,v2] j784s4: move TI_CORE_INITRAMFS_KERNEL_MODULES to j784s4-evm.conf

From: Vitor Soares <vitor.soares@toradex.com>

TI_CORE_INITRAMFS_KERNEL_MODULES is set in j784s4.inc, causing all
machines based on the J784S4 SoC to unconditionally build and deploy
an initramfs. The cdns-pltfrm and ti-j721e-ufs modules are required
by the EVM to access UFS storage and are not a SoC-level requirement.

Moving it to j784s4-evm.conf scopes initramfs creation to the board
that needs it, allowing other integrators to rely on the empty default
without explicit overrides.

Changes in v2:
- Added project + branch specifier to subject line

Tested on Toradex Aquila AM69 with bsp-mainline. EVM not tested.

Hello,

The recent commit 135dfe3f2620 ("ti-bsp: Make ti-6_18 the default BSP") making
the ti-6_18 the default BSP appears to have broken our builds, which is what
this patch was trying to prevent.

With ti-6_18 now default, all J784s4 based machines are forced into initramfs
build through TI_CORE_INITRAMFS_KERNEL_MODULES in j784s4.inc, regardless of
whether they actually need these EVM specific modules.

Our Toradex Aquila AM69/TDA4 SoM doesn't use UFS storage and doens't need
initrafs. Our build now fail because the SoC include forces image levl
integration decisions.

Can this patch be considered, or am I missing something about how to handle this
scenario?

Thanks,
Vitor Soares

We are still looking into your patch (lots of moving parts over here).  In the meantime, you can always just clear out the value of
TI_CORE_INITRAMFS_KERNEL_MODULES in your machine file:

TI_CORE_INITRAMFS_KERNEL_MODULES = ""

That will turn off the initramfs code.
