Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

BTicino Mamoj board: =================== Build: $ make mrproper $ make imx6dl_mamoj_defconfig $ make This will generate the SPL image called SPL and the u-boot-dtb.img. The following methods can be used for booting Mamoj boards: 1. USB SDP boot 2. eMMC boot (via DFU) 3. Falcon mode 1. USB SDP boot: --------------- - Build imx_usb_loader $ git clone git://github.com/boundarydevices/imx_usb_loader.git $ cd imx_usb_loader $ make - Build the BSP and copy SPL, u-boot-dtb.img in imx_usb_loader directory - Put the board in "Serial Download Mode" - Plug-in USB-to-Serial, Open minicom 1152008N1 and USB OTG cables to Host - Turn-on board - Identify VID/PID using lsusb Bus 001 Device 010: ID 15a2:0061 Freescale Semiconductor, Inc. i.MX 6Solo/6DualLite SystemOnChip in RecoveryMode - Update the conf files imx_usb.conf 0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf mx6_usb_rom.conf mx6_usb hid,1024,0x910000,0x10000000,512M,0x00900000,0x40000 SPL:jump header2 mx6_usb_sdp_spl.conf mx6_spl_sdp hid,uboot_header,1024,0x910000,0x10000000,512M,0x00900000,0x40000 u-boot-dtb.img:jump header2 - Launch the loader $ ./imx_usb We can see U-Boot boot from USB SDP on minicom 2. eMMC boot via DFU: -------------------- Once booted from USB SDP, program the eMMC as below(make sure to connect USB OTG) - Change eMMC partition config => mmc partconf 2 1 0 0 - Partition eMMC on host => ums 0 mmc 2 Host will able to detect the eMMC disk as UMS, partition the same. - Program SPL => setenv dfu_alt_info $dfu_alt_info_spl => dfu 0 mmc 2 At Host # dfu-util -D SPL -a spl - Program u-boot-dtb.img => setenv dfu_alt_info $dfu_alt_info_uboot => dfu 0 mmc 2 At Host # dfu-util -D u-boot-dtb.img -a u-boot Poweroff and Poweron the board and see U-Boot booting from eMMC. 3. Falcon mode: -------------- - Skip 10M space and create dual partitions for eMMC, start sector is 20480 Partition Map for MMC device 2 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 20480 131072 c52e78be-01 83 2 151552 7581696 c52e78be-02 83 - Write uImage => fatload mmc 2:1 $kernel_addr_r uImage => mmc write $kernel_addr_r 0x1000 0x4000 - Write dtb and args => setenv bootargs console=ttymxc2,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rw quiet => fatload mmc 2:1 $fdt_addr_r imx6dl-mamoj.dtb => spl export fdt $kernel_addr_r - $fdt_addr_r => mmc write 0x13000000 0x800 0x800 Poweroff and Poweron the board and see Linux booting directly after SPL. -- Jagan Teki <jagan@amarulasolutions.com> 03/12/18
