2018-04-06stm32mp1: select boot device and partitionPatrick Delaunay
Bootrom loads SPL from SDCARD or eMMC according BootPin selection. Then SPL loads U-Boot on the same mmc device with the following predefined GPT partitioning: on SDCARD: gpt partitioning 1: SPL 2: SPL#2 3: U-Boot 4: bootable partition on eMMC: The 2 boot partitions are used for SPL (2 copy) boot1: SPL boot2: SPL#2 The user partition use gpt partitioning 1: U-Boot 2: bootable partition This patch select the correct SPL partition (3 for SDCARD on mmc0 and 1 for eMMC on mmc1) according the BootRom information saved in TAMP register and based on configuration flasg: - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION => for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new) => for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot And the correct boot_targets is selected according the environment variables boot_device and boot_instance, with preboot command, to search the bootable partition with kernel on this device (generic distro support).

2018-03-19board: st: add generic board for STM32MP1 familyPatrick Delaunay
Add first support for STM32MP157C-ED1 board with "Basic" boot chain 1/ Boot Rom: load SPL with STM32 image header in SYSRAM 2/ SPL: power up and initialize the DDR and load U-Boot image from SDCARD in DDR 3/ U-Boot: search and load extlinux.conf in SDCARD (DISTRO activated) Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2018-03-19arm: stm32: add new architecture for STM32MP familyPatrick Delaunay
- add new arch stm32mp for STM32 MPU/Soc based on Cortex A - support for stm32mp157 SOC - SPL is used as first boot stage loader - using driver model for all the drivers, even in SPL - all security feature are deactivated (ETZC and TZC) - reused STM32 MCU drivers when it is possible Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
