Re: [U-Boot] [BUG] simple-bus and rsa-sw with DM_FLAG_PRE_RELOC

As of v2019.07-rc1, u-boot does fail to boot without any messages on qemu-arm64 when configured with qemu_arm64_defconfig plus CONFIG_RSA/RSA_SOFTWARE_EXP. (Note that RSA_SOFTWARE_EXP also declares itself with DM_FLAG_PRE_RELOC.)

By bisecting between v2019.04 and v2019.07, I found that the following commit triggered this regression:

    commit 3a7c45f6a772

        simple-bus: add DM_FLAG_PRE_RELOC flag to simple-bus driver

What's wrong with this?

I just tested it and it boots for me.

$ make qemu_arm64_defconfig $ make menuconfig adding CONFIG_RSA via "Library routines" -> "Security support" -> "Use RSA Library" $ make

$ qemu-system-aarch64 -machine virt -cpu cortex-a57 -bios u-boot.bin -nographic
