[PATCH v2 0/3] Introduction of STiH418 based 4KOpen board

[Alain Volmat]

This serie introduces the 4KOpen (stih418-b2264) board based
on a stih418 soc. Since it is the first board to use the spi-fsm
SPI NOR controller available since stih407, the controller is
also added within the stih407-family DT.
It also contains a fix within the stih418 DT since the rng11 is not
available on this platform and is thus disabled.

Alain Volmat (3):
  ARM: dts: sti: add the spinor controller node within stih407-family
  ARM: dts: sti: disable rng11 on the stih418 platform
  ARM: dts: sti: Introduce 4KOpen (stih418-b2264) board

[PATCH v2 1/3] ARM: dts: sti: add the spinor controller node within stih407-family

[Alain Volmat]

The STiH407 family (and further versions STiH410/STiH418) embedded
a serial flash controller allowing fast access to SPI-NOR.
This commit adds the corresponding node, relying on the st-spi-fsm
drivers.

[PATCH v2 2/3] ARM: dts: sti: disable rng11 on the stih418 platform

[Alain Volmat]

The rng11 is not available on the STiH418 hence is disabled in the
stih418.dtsi
