From: Jan Kiszka <jan.kiszka@siemens.com>
Prepares for the addition of the IOT2050 board which is based on the TI
AM65x. The board comes in two variants, Basic and Advanced, so there are
separate dts files. Furthermore, the SPL has its own device tree.
Based on original board support by Le Jin, Gao Nian and Chao Zeng.

From: Jan Kiszka @ 2020-12-04 7:59 UTC (permalink / raw)
To: u-boot
From: Jan Kiszka <jan.kiszka@siemens.com>
This adds support for the IOT2050 Basic and Advanced devices. The Basic
used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS
quad-core version.
Both variants are booted via a Siemens-provided FSBL that runs on the R5
cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot
SPL, ATF and TEE have to reside in SPI flash.
Full integration into a bootable image can be found on
https://github.com/siemens/meta-iot2050
Based on original board support by Le Jin, Gao Nian and Chao Zeng.

+SIMATIC IOT2050 BASIC and ADVANCED
+==================================
+
+The SIMATIC IOT2050 is an open industrial IoT gateway that is using the TI
+AM6528 GP (Basic variant) or the AM6548 HS (Advanced variant). The Advanced
+variant is prepared for secure boot.
+
+The IOT2050 starts only from OSPI. It loads a Siemens-provided bootloader
+called SE-Boot for the MCU domain (R5F cores), then hands over to ATF and
+OP-TEE, before booting U-Boot on the A53 cores. This describes how to build all
+open artifacts into a flashable image for the OSPI flash. The flash image will
+work on both variants.
+
+
+Dependencies
+------------
+
+ATF: Upstream release 2.4 or newer
+OP-TEE: Upstream release 3.10.0 or newer
+
+Binary dependencies can be found in
+https://github.com/siemens/meta-iot2050/tree/master/recipes-bsp/u-boot/files/prebuild.
+The following binaries from that source need to be present in the build folder:
+
+ - tiboot3.bin
+ - sysfw.itb
+ - sysfw.itb_HS
+
+
+Building
+--------
+
+Make sure that CROSS_COMPILE is set appropriately:
+
+ export CROSS_COMPILE=aarch64-linux-gnu-
+
+ATF:
+
+ make PLAT=k3 SPD=opteed K3_USART=1
+
+OP-TEE:
+
+ make PLATFORM=k3-am65x CFG_ARM64_core=y \
+ CFG_TEE_CORE_LOG_LEVEL=2 CFG_CONSOLE_UART=1
+
+U-Boot:
+
+ export ATF=/path/to/bl31.bin
+ export TEE=/path/to/tee-pager_v2.bin
+ make iot2050_defconfig
+ make
+
+
+Flashing
+--------
+
+Via U-Boot:
+
+ sf probe
+ load mmc 0:1 $loadaddr /path/to/flash.bin
+ sf update $loadaddr 0x0 $filesize
+
+Via external programmer Dediprog SF100 or SF600:
+
+ dpcmd --vcc 2 -v -u flash.bin
