[Buildroot] ARM qemu versatile defconfig

[Paulo Matos]

Hi,

I am trying to get a emulation environment based on arm 32bits to
emulate the native environment we have setup with
raspberrypi3_defconfig.

The only existing defconfig I can see that could help me with this is
qemu_arm_versatile_defconfig however, I do not understand what this
'versatile' refers to or find any online documentation about it.

Could someone explain what this 'versatile' defconfig corresponds to in
terms of emulated hardware? Or is it versatile because you should use
'make menuconfig' later to specifically configure it for your needs?

Kind regards,

Versatile is one of the ARM machines emulated by Qemu. If you want to
be closer to RPi3, I would suggest to use our
qemu_arm_vexpress_defconfig instead, and follow the instructions of
board/qemu/arm-vexpress/readme.txt to use it.

Best regards,

Thomas

Oh! I just learned Versatile is actually an ARM trademark. I thought
versatile here was used as an adjective. :)

Thanks for the suggestion on vexpress - I will give this a go.
