Simon Glass db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

U-Boot for the NXP i.MX8MN EVK board

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

Get and Build the ARM Trusted firmware
======================================
Note: srctree is U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_4.19.35_1.1.0
$ make PLAT=imx8mn bl31
$ cp build/imx8mn/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/ddr4*.bin $(srctree)

Build U-Boot
============
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mn_ddr4_evk_defconfig
$ export ATF_LOAD_ADDR=0x960000
$ make flash.bin

Burn the flash.bin to MicroSD card offset 32KB
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32

Boot
====
Set Boot switch to SD boot
