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.

How to use U-Boot on MYiR MYS-6ULX Single Board Computer
--------------------------------------------------------
- Configure and build U-Boot for MYS-6ULX iMX6ULL:
$ make mrproper
$ make myir_mys_6ulx_defconfig
$ make
This will generate SPL and u-boot-dtb.img images.
Boot from MMC/SD:
- The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
$ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Boot mode settings:
Boot switch position: SW1 -> 0
SW2 -> 1
SW3 -> 0
SW4 -> 1
Boot from NAND:
- Boot the board using SD/MMC or Serial download and load the SPL into memory
either from SD/MMC or TFTP.
Default MTD layout is 512k(spl),1m(uboot),1m(uboot-dup),-(ubi)
Flash SPL to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr SPL
$ nand erase.part spl
$ nandbcb init $loadaddr 0x0 $filesize
Flash u-boot proper to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr u-boot-dtb.img
$ nand erase.part uboot
$ nand write $loadaddr uboot $filesize
- Boot mode settings:
Boot switch position: SW1 -> 1
SW2 -> 0
SW3 -> 0
SW4 -> 1
- Connect the Serial cable to UART0 and the PC for the console.
- Reset the board using and U-Boot should boot from NAND.
