+How to Update U-Boot on imx6ulz_smm_m2 board
+--------------------------------------------
+
+Required software on the host PC:
+
+- UUU: https://github.com/NXPmicro/mfgtools
+
+Build U-Boot for m2:
+
+$ make mrproper
+$ make imx6ulz_smm_m2_defconfig
+$ make
+
+This generates the SPL and u-boot-dtb.img binaries.
+
+1. Loading U-Boot via USB Serial Download Protocol
+
+Copy SPL and u-boot-dtb.img to the uuu folder.
+
+Load the U-Boot via USB:
+
+$ sudo uuu -v -b nand_script.lst u-boot-with-spl.imx
+
+where nand_script.lst contains the following:
+
+uuu_version 1.2.39
+
+# @_flash.bin | bootloader
+# @_image [_flash.bin] | image burn to nand, default is the same as bootloader
+
+# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
+SDP: boot -f _flash.bin
+
+# This command will be run when ROM support stream mode
+# i.MX8QXP, i.MX8QM
+SDPS: boot -f _flash.bin
+
+# These commands will be run when use SPL and will be skipped if no spl
+# SDPU will be deprecated. please use SDPV instead of SDPU
+# {
+SDPU: delay 1000
+SDPU: write -f _flash.bin -offset 0x57c00
+SDPU: jump
+# }
+
+# These commands will be run when use SPL and will be skipped if no spl
+# if (SPL support SDPV)
+# {
+SDPV: delay 1000
+SDPV: write -f _flash.bin -offset 0x11000
+SDPV: jump
+# }
+
+FB: ucmd setenv fastboot_buffer ${loadaddr}
+FB: download -f _image
+FB: ucmd if test ! -n "$fastboot_bytes"; then setenv fastboot_bytes $filesize; else true; fi
+# Burn image to nandfit partition if needed
+FB: ucmd if env exists nandfit_part; then nand erase.part nandfit; nand write ${fastboot_buffer} nandfit ${fastboot_bytes}; else true; fi;
+FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${fastboot_bytes}
+FB: Done
+
+Then U-Boot starts and its messages appear in the console program.
+
+Use the default environment variables:
+
+=> env default -f -a
+=> saveenv

Introduce BSH SystemMaster (SMM) M2 board family, which consists of: imx6ulz SMM M2 and imx6ulz SMM M2 PRO boards. Add support for imx6ulz BSH SMM M2 board: - 128 MiB DDR3 RAM - 256MiB Nand - USBOTG1 peripheral - fastboot. Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> --- Changes V4->V5: - Add README - Drop ramdisk_addr_r - Fix fdt_addr_r - Fix mtd parts from mtdparts=mdtparts= to mtdparts= - Adjust partition loading name according to mtdparts - Move CONFIG_SPL_BSS_START_ADDR=0x84100000 to half of 128Mb, this address was above 128Mb but module has only 128Mb - Enable bbt table for nand - Test bootloader with NXP and MAINLINE kernel up to 6.0-rc2 Changes V3->V4: - really drop the define in include Changes V2->V3: - remove CONFIG_SYS_HZ default is 1000 from include - make const uart4 Changes V1->V2: - Adjust board due to the migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h - Drop reference to freescale board in imx6ulz_smm_m2 include file --- arch/arm/dts/Makefile | 1 + arch/arm/dts/imx6ulz-bsh-smm-m2-u-boot.dtsi | 35 +++++ arch/arm/dts/imx6ulz-bsh-smm-m2.dts | 146 ++++++++++++++++++++ arch/arm/mach-imx/mx6/Kconfig | 12 ++ board/bsh/imx6ulz_smm_m2/Kconfig | 12 ++ board/bsh/imx6ulz_smm_m2/MAINTAINERS | 6 + board/bsh/imx6ulz_smm_m2/Makefile | 6 + board/bsh/imx6ulz_smm_m2/README | 67 +++++++++ board/bsh/imx6ulz_smm_m2/imx6ulz_smm_m2.c | 53 +++++++ board/bsh/imx6ulz_smm_m2/spl.c | 130 +++++++++++++++++ configs/imx6ulz_smm_m2_defconfig | 80 +++++++++++ include/configs/imx6ulz_smm_m2.h | 78 +++++++++++ 12 files changed, 626 insertions(+) create mode 100644 arch/arm/dts/imx6ulz-bsh-smm-m2-u-boot.dtsi create mode 100644 arch/arm/dts/imx6ulz-bsh-smm-m2.dts create mode 100644 board/bsh/imx6ulz_smm_m2/Kconfig create mode 100644 board/bsh/imx6ulz_smm_m2/MAINTAINERS create mode 100644 board/bsh/imx6ulz_smm_m2/Makefile create mode 100644 board/bsh/imx6ulz_smm_m2/README create mode 100644 board/bsh/imx6ulz_smm_m2/imx6ulz_smm_m2.c create mode 100644 board/bsh/imx6ulz_smm_m2/spl.c create mode 100644 configs/imx6ulz_smm_m2_defconfig create mode 100644 include/configs/imx6ulz_smm_m2.h
