ARM: SoC platform updates for 4.20
A couple of platforms change hands in the MAINTAINERS file:
- Linus Walleij lists himself for the ARM Reference platforms:
versatile, vexpress, integrator and realview. He has been the main
contributor for these for a while, and makes it official now.
- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the
Actions Semi machines
- Nicolas Ferre lists updates the MAINTAINER listing for the AT91
platform: Ludovic Desroches is now a co-maintainer for the platform, and
several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
Codrin Ciubotariu) take over individual device drivers.
Thanks everyone for working on this, and welcome to the new maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time
it's the i.MX 6ULZ 32-bit single-core version.
On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is
used on the reference board for the CIP Super Long Term Support (SLTS)
Linux Kernels.
