Hi folks,

This series adds initial SoC support for the Exynos 8895 SoC and also
initial board support for Samsung Galaxy S8 phone (SM-G950F), codenamed
dreamlte.

The Exynos 8895 SoC is also used in S8 Plus (dream2lte), Note 8 (greatlte)
and Meizu 15 Plus (m1891). Currently DT is added for the Exynos 8895 SoC
and dreamlte, but it should be really easy to adapt for the other devices
with the same SoC.

The support added in this series consists of:
* cpus
* pinctrl
* gpio
* simple-framebuffer
* pstore

This is enough to reach a minimal initramfs shell using an upstream kernel.
More platform support will be added in the future.

The preferred way to boot this device is by using a small shim bl called
uniLoader [1], which packages the mainline kernel and DT and jumps to
the kernel. This is done in order to work around some issues caused by
the stock, and non-replacable Samsung S-Boot bootloader. For example,
S-Boot leaves the decon trigger control unset, which causes the framebuffer
to not refresh.

Kind regards,

Ivaylo.
