[PATCH 0/2] Enable NAND support on Armada 7K/8K

[PATCH 0/2] Enable NAND support on Armada 7K/8K

[Gregory CLEMENT]

Hi Boris,

this short series enables the NAND controller on the Armada 7K/8K
SoCs. The IP used is the same that the other mvebu SoC, so we only
need to be bale to build it for this SoCs and updating the device
tree.

The first patch should go to mtd and the second one to arm-soc through
mvebu.

The patches are completely independent.

Thanks,

Gregory

[PATCH 1/2] mtd: nand: pxa3xx_nand: enable building on mvebu 64-bit platforms

[Gregory CLEMENT]

The controller supported by the pxa3xx_nand driver is also available on
the mvebu 64-bit SoCs, such as the Armada 7K and Armada 8K SoCs. This
patch updates the Kconfig dependency to allow building the kernel for
this SoC family too.

[PATCH 2/2] ARM64: dts: marvell: add NAND support on the CP110 master

[Gregory CLEMENT]

The NAND controller used in A7K/A8K is present on the CP110 master
part. It is compatible with the pxa-nand driver.

Unlike most of the controller on the CP110 this one is only present on
the master for the Armada 8K SoCs.

Stupid minor nit: there are two spaces here, there should be one. No
need to send a v2 just for this, I'm sure Boris will happily fix this
when applying :-)

Actually this is wrong. The controller is present on both CP, but
because of the muxing only the one present on the CPS is available on
the Armada 8K.

I will send a new version fixing it.
