Simon Glass 401d1c4f5d common: Drop asm/global_data.h from common header 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.

U-Boot for the Beacon EmbeddedWorks Devkit

Quick Start
===========
- Build the ARM Trusted firmware binary
- Get ddr firmware
- Build U-Boot
- Boot

Get and Build the ARM Trusted firmware
======================================
Note: $(srctree) is U-Boot source directory

$ git clone https://source.codeaurora.org/external/imx/imx-atf
$ git checkout imx_4.19.35_1.0.0
$ make PLAT=imx8mm bl31 ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-
$ cp build/imx8mm/release/bl31.bin $(srctree)

Get the DDR firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.5.bin
$ chmod +x firmware-imx-8.5.bin
$ ./firmware-imx-8.5
$ cp firmware-imx-8.5/firmware/ddr/synopsys/lpddr4*.bin $(srctree)

Build U-Boot
============
$ make imx8mm_beacon_defconfig
$ make flash.bin CROSS_COMPILE=aarch64-linux-gnu- ATF_LOAD_ADDR=0x920000

Burn U-Boot to microSD Card
===========================
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33

Boot
====
Set Boot switch to SD boot
