6944a95091 oxnas: move gmac soc glue from mach to stmmac driver
Still a lot of kernel-version ifdef'ery, but imho that's easy to remove
once obsoleted and avoids duplicate code in the meantime.

2ef587a8fc oxnas: clk-oxnas: rework pllb enable function
kernel lock debugging unveiled that we should not call
of_reset_control_get inside a clock's enable operation (see below)

move of_reset_control_* previously used in pllb_clk_enable to new
pllb_clk_prepare and pllb_clk_unprepare functions.
use a container to carry runtime information.

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 :)

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)
