Hi, Simon Glass：
        we have an issue based on this patch below, can you help us ?
        Patch：https://patchwork.ozlabs.org/project/uboot/patch/20220117150428.1580273-2-sj...
Our Environment：
Qemu Version：7.0.0
U-boot Baseline Version: 2021.10
Steps:
        1. we have only patched "[v2,02/16] arm: qemu: Add an SPL build", not all the "passage: Define a standard for firmware data flow" series patchs.
    2. Baseed on this patch, we have made the following modifications：
            a. arch/arm/dts/qemu-arm-u-boot.dtsi （Left is original, right is modified， we think they are actually the same）
    3. After compiling, image.bin is generated, image.map is as follows（we think it's ok, spl base addr is 0x00000000, and u-boot base addr is 0x00010000）：

but when we use following command to execute, it will block.

command: ./qemu-system-arm -machine virt -nographic -bios image.bin
result：
 5.  some key files size：
image.bin： 767936
u-boot.bin：694764
u-boot-spl.bin：15112
We don't know what could be causing this problem, hope you can help us !
I cannot repeat this problem.
