We do not control the value of KERNEL_DEVICETREE, that is auto generated based on KERNEL_DEVICETREE_PREFIX and the latest mainline kernel version that we test. The value for KERNEL_DEVICETREE is tied to the DTBs that exist only in the latest stable kernel. For all other things we use KERNEL_DEVICETREE_PREFIX which already contains enough to pick up this new DTB. So the above change needs to be removed. > -FIT_CONF_DEFAULT_DTB = "ti/k3-am625-sk.dtb" > +FIT_CONF_DEFAULT_DTB = "ti/k3-am6254xxl-sk.dtb" > +FIT_CONF_DEFAULT_DTB:bsp-ti-6_6 = "ti/k3-am625-sk.dtb" > +FIT_CONF_DEFAULT_DTB:bsp-ti-6_1 = "ti/k3-am625-sk.dtb" > > UBOOT_MACHINE = "am6254xxl_evm_a53_defconfig" >

The new kernel dtbs for am62x SiP have been merged to ti-linux-kernel as of f9579207b081 ("arm64: dts: ti: Add support for AM6254xxl SiP SK") on ti-linux-6.12.y-cicd. Note that AM6254xxl is the OPN for am62x SiP and expands as follows: AM6254XXL |||| |||+-- Feature Lookup (L indicates 512MiB of integrated LPDDR4) ||+--- Clock Speed |+---- Silicon PG Revision +----- Core configuration (4 indicates A53's in Quad core config) This patch updates am62x SiP machine config to make use of the new dtbs.
