Hi, Stefan,
The A0 SoC is not for production, it is engineering samples only. Marvell has no plans for supporting this SoC in the future. I believe that once you get a replacement for your board there will be no other customers using A0 SoC.
Regard Kosta

Align the Armada-8040-db SPI and I2C DTS settings with latest A8040 DB settings:
- disable i2c0 and spi0 on AP (pins are reserved for eMMC)
- disable cps_i2c0 on CP1
- enable spi1 on CP1 (the new location of the boot flash)
Thanks. I understand that the current SPI / I2C settings are still valid for boards with earlier SoC revisions. Is this correct? Would it make sense to move the old version into a new file then, perhaps:
arch/arm/dts/armada-8040-db-revA.dts
?
This would be handy for users of this version at least for a short period of time. This new file can be removed once its not needed any more in a few months.
If you think this is a good idea, could you please add this new file in a new patch to this patchset in v2?
