MIPS: dts: use physical addresses (as Linux does)
With IOMEM() adapted for MIPS we can use physical addresses
in device tree reg property.
has switched MIPS dts files to physical addresses usage.
The patch was tested on qemu, but qemu malta board is tolerant
of using physical addresses for accesing to device
(Ingenic JZ4755 and JZ4780 processors are tolerant too!).
But other CPUs (e.g. Loongson LS1B) can throw an exception
in this situation.
Additional physical address to virtual address translation
on MIPS is needed.
We already have this in include/common.h
#if defined(CONFIG_MIPS)
#include <asm/addrspace.h>
#define IOMEM(addr) ((void __force __iomem *)CKSEG1ADDR(addr))
#else
#define IOMEM(addr) ((void __force __iomem *)(addr))
#endif
So use IOMEM() to fix dev_request_mem_region() return value.

The CPSW has two slaves. When one of them fails to setup continue
anyway with the other one. This fixes a crash in the beaglebone black
which only has one slave connected. The code doesn't find a phy on
the second slave and bails out, but the error path is broken: It frees
the private data structures which contains used resources.

As the SMC1111 has a shared pool of 2k memory buckets for both
transmission and reception, and as there are variants which have as few
as 4 buckets in total, the memory pool can be hogged by unclaimed
receptions, and impeed any further transmission.
This happens on the zylonite pxa board, where 4 packets, most probably
icmp and arp, fill the 4 buckets, preventing any further ethernet
transmission, and stalling the driver.
The fix is rather rough : whenever all the buckets are filled by
reception packets, and if a transmission is required, the transmission
code path will empty up all received packets.

UBI assumes that ubi_attach_info will only contain ubi_ainf_volume
structures for volumes with at least one LEB.
In scanning mode this is true because UBI can nicely create a ubi_ainf_volume
on demand while creating the EBA table.
For fastmap this is not true, the fastmap on-flash structure has a list of
all volumes, the ubi_ainf_volume structures are created from this list.
So it can happen that an empty volume ends up in init_volumes().
We can easely deal with that by looking into ->leb_count too.

nor_erase_prepare() will be called before erase a NOR flash, it will program '0'
into a block to mark this block. But program data into a erasure interrupted block
can cause program timtout(several minutes at most) error, could impact other
operation on NOR flash. So UBIFS can read this block first to avoid unneeded
program operation.
This patch try to put read operation at head of write operation in
nor_erase_prepare(), read out the data.
If the data is already corrupt, then no need to program any data into this block,
just go to erase this block.
This patch is validated on Micron NOR flash, part number is：JS28F512M29EWHA

net: phy: add minimal support for QSGMII PHY
This commit adds the necessary definitions for the PHY layer to
recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
defined at
http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
is "is a method of combining four SGMII lines into a 5Gbit/s
interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
data and a single LVDS clock signal. QSGMII uses significantly fewer
signal lines than four SGMII busses."
This type of MAC <-> PHY connection might require special handling on
the MAC driver side, so it should be possible to express this type of
MAC <-> PHY connection, for example in the Device Tree.

USB core isn't too strict about allocation/deallocation and
add/remove sequences of usb devices. Especially, error paths
and device tear-down are kind of broken and cause hangs on
failing usb device detect.
This patch improves the situation by introducing a
usb_free_device() that tears down allocated resources by
usb_alloc_new_device(). usb_remove_device() now only deals
with resources that have been added by usb_new_device().
Also, error handling is fixed or improved to ensure that no

Adding a usb device increases dev_index every time a new device is
allocated. Removing a usb device does not decrease again, of course.
As we print the number of detected usb devices after each usb bus
scan based on dev_index, we cannot trust dev_index here. Keep track
of the correct number of (currently) detected usb devices by
introducing an independent dev_count that gets increased on detect
and decreased on remove.

On Marvell MVEBU SoCs internal registers are usually remapped from reset
default. While Dove and Kirkwood always had their registers remapped,
some Armada 370 and XP where shipped with bootloaders that did not remap
them.
On Barebox these registers are remapped early and on all MVEBU SoCs, so
provided DTs should always reflect that in their mbus ranges property.
This patch registers a fixup for DTBs and allows individual SoCs to add
specific remap ranges to the fixup list. The fixup is registered on
pure_initcall to even allow to fixup pbl or appended DTBs.
