This patch moves all Armada 370/XP/38x/39x SPI controller nodes from the 'internal-regs' node down into the 'soc' node. This is in preparation to enable the usage of the SPI direct access mode. A follow-up patch will add the static MBus mappings for the SPI devices into the 'reg' property of the SPI controller DT node. By moving these SPI controller nodes, this patch also makes use of the labels rather than keeping the tree structure.

* Note: this Device Tree assumes that the bootloader has remapped the
|
|
* internal registers to 0xf1000000 (instead of the old 0xd0000000).
|
|
* The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
|
|
* bootloaders provided by Marvell. It is used in recent versions of
|
|
* DSM software provided by Synology. Nonetheless, some earlier boards
|
|
* were delivered with an older version of u-boot that left internal
|
|
* registers mapped at 0xd0000000. If you have such a device you will
|
|
* not be able to directly boot a kernel based on this Device Tree. In
|
|
* that case, the preferred solution is to update your bootloader (e.g.
|
|
* by upgrading to latest version of DSM, or building a new one and
|
|
* installing it from u-boot prompt) or adjust the Devive Tree
|
|
* (s/0xf1000000/0xd0000000/ in 'ranges' below).
