pci: PCIe driver for Marvell Armada 370/XP systems
This driver implements the support for the PCIe interfaces on the
Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to
cover earlier families of Marvell SoCs, such as Dove, Orion and
Kirkwood.
The driver implements the hw_pci operations needed by the core ARM PCI
code to setup PCI devices and get their corresponding IRQs, and the
pci_ops operations that are used by the PCI core to read/write the
configuration space of PCI devices.
Since the PCIe interfaces of Marvell SoCs are completely separate and
not linked together in a bus, this driver sets up an emulated PCI host
bridge, with one PCI-to-PCI bridge as child for each hardware PCIe
interface.
In addition, this driver enumerates the different PCIe slots, and for
those having a device plugged in, it sets up the necessary address
decoding windows, using the mvebu-mbus driver.

ENGR00258733 WEIM-NOR: mtd: cfi_cmdset_0002: Do not release the mutex lock
The NOR(M29W256GL7AN6E) may suffers a write-buffer timeout during
the bonnie++/ubifs stress test. Micron has confirmed that it is
a silicon bug in the Nor.
This patch is just a workaround to fix this issue for this NOR.
With this patch, the read/write/erase will do in the synchronous way.
ENGR00257947 mtd: use memcpy to replace the memcpy_fromio
During the read of NOR, the kernel actually calls the inline_map_copy_from()
to read the data out. And inline_map_copy_from() will use the memcpy_fromio()
to do the real job.
The memcpy_fromio macro maps _memcpy_fromio() in the current code.
But the _memcpy_fromio() will use readb() to do the copy work one byte
by one byte. This makes the read performance of NOR very slow(about 2~3MB/s).
A similiar discussion could be found in:
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-November/003860.html
This patch replace the memcpy_fromio with memcpy which is optimized by the
kernel.
