This should replace the stm32mp157a-avenger96.dts with the new device tree files split into the STM32MP15 DHCOR SoM definition and the Avenger96 baseboard like it's done in Linux and U-Boot. Differences to stm32mp157a-avenger96.dts: - Enable sdmmc2 for booting from eMMC - improved clock settings like in U-Boot commit b6055945 "ARM: dts: stm32: Adjust PLL4 settings on AV96 again" - improved DDR settings for DHSOMs like in U-Boot commit 92ca0f74 "ARM: dts: stm32: Synchronize DDR setttings on DH SoMs" TF-A with this new dts(i) files on this board was fully tested with the latest OP-TEE developer setup.
