The Cortex-M Prototyping System (or V2M-MPS2) is designed for
prototyping and evaluation Cortex-M family of processors including the
latest Cortex-M7
It comes with a range of useful peripherals including 8MB single cycle
SRAM, 16MB PSRAM, Ethernet, QSVGA touch screen panel, 4bit RGB VGA
connector, Audio, SPI and GPIO.

Application Notes 385 and 386 shares the same memory map and features
except the CPU is used. AN385 is supplied with Cortex-M3 CPU and AN386
is supplied with Cortex-M4.

The rootfs should be independent from the board.
In my opinion, this type of bootargs should not be part of the DTS.

I have no strong opinion on this, but quick grep shows plenty places
where the same happens, and even [1] has rootfs specific option as an
example. So if there is no strong call to remove rdinit from bootargs,
I'd prefer to keep it as it makes testing easier for me.

I think "rdinit=/sbin/init" is redundant, that is what we try running
anyway, so I don't see any downside in removing it.

Fair point.
@Sudeep could you fixup it locally or I need to respin?

Application Notes 399 and 400 shares the same memory map and
features. Both are shipped with Cortex-M7 and have the same peripheral
as AN385/AN386, but with different location of PSRAM and Ethernet
controller.

This patch update ARM Versatile Express entry to cover bits needed for
Cortex-M Prototyping System (MPS2 platform). So patches for the latter
are collected by existing Vexpress and Juno maintainers (Liviu, Sudeep,
Lorenzo) and find their way upstream via Vexpess and/or Juno trees.
