dcc34574ef oxnas: bring in new oxnas target
Reboot the oxnas target based on Linux 4.14 by rebasing our support on
top of the now-existing upstream kernel support.
This commit brings oxnas support to the level of v4.17 having upstream
drivers for Ethernet, Serial and NAND flash.
Botch up OpenWrt's local drivers for EHCI, SATA and PCIe based on the
new platform code and device-tree.
Re-introduce base-files from old oxnas target which works for now but
needs further clean-up towards generic board support.

Functional issues:
 * PCIe won't come up (hence no USB3 on Shuttle KD20)
 * I2C bus of Akitio myCloud device is likely not to work (missing
   debounce support in new pinctrl driver)

Code-style issues:
 * plla/pllb needs further cleanup -- currently their users or writing
   into the syscon regmap after acquireling the clk instead of using
   defined clk_*_*() functions to setup multipliers and dividors.
 * PCIe phy needs its own little driver.
 * SATA driver is a monster and should be split into an mfd having
   a raidctrl regmap, sata controller, sata ports and sata phy.

Tested on MitraStar STG-212 aka. Medion Akoya MD86xxx and Shuttle KD20.

74a9e1c1b0 oxnas: sata_oxnas: refactoring phase 2
- replaced // comments by /* comments */
 - added line-breaks where needed
 - fixed white-space according to kernel style
 - fixed some obvious spelling mistakes in comments and printks
 - removed some unneeded left-overs imported from vendor code-base
 - replaced printk(...) by libata macros where possible

feda47451f oxnas: sata_oxnas: refactoring phase 1
locking for 2nd port and hwraid was added from vendor's GPL code which
doesn't comply with current kernel coding style.

 - moved all global variables into host_priv
 - renamed locks
 - sanetized acquire() and release() parameter list

9432cbd577 oxnas: add support for 2nd S-ATA port to sata_oxnas driver
similar to mv_sata, use nr-ports attribute from device tree.
import and adapt locking code from vendor GPL sources.
add dma controller handling, it may be used in future to avoid
full core resets similar to the vendor SDK's "progressive cleanup"
function.

this is still very dirty and aimed to first of all do things
quite exactly like the reference code. and it somehow works.
obviously there is lots of room for improvement :)

1fa7c8587d oxnas: add copyright header to sata_oxnas
sata_oxnas.c is obviously a refactored version of sata_ox820.c
which does contain this header.

72b58f2eb1 add new target 'oxnas'
This is the oxnas target previously developed at
http://gitorious.org/openwrt-oxnas
Basically, this consolidates the changes and addtionas from
http://github.org/kref/linux-oxnas
into a new OpenWrt hardware target 'oxnas' adding support for
 PLX Technology NAS7820/NAS7821/NAS7825/...
formally known as
 Oxford Semiconductor OXE810SE/OXE815/OX820/...

For now there are 4 supported boards:
Cloud Engines Pogoplug V3 (without PCIe)
 fully supported

Cloud Engines Pogoplug Pro (with PCIe)
 fully supported

MitraStar STG-212
 aka ZyXEL NSA-212,
 aka Medion Akoya P89625 / P89636 / P89626 / P89630,
 aka Medion MD 86407 / MD 86805 / MD 86517 / MD 86587
 fully supported, see http://wiki.openwrt.org/toh/medion/md86587

Shuttle KD-20
 partially supported (S-ATA driver lacks support for 2nd port)
