This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

Add a new kernel config option for generic firmware partition
split support and change the uImage split support to depend on
the new option. Aslo rename the MTD_UIMAGE_SPLIT_NAME option to
MTD_SPLIT_FIRMWARE_NAME to make it more generic.
The patch is in preparation for multiple firmware format
support.

Without this patch it is impossible to read et_swtype, because the 1
byte space is needed for the terminating null byte. Now it should be
possible to read decimal and hex vars of max 8 bit.

Most of the bcm47xx devices use TRX format for storing kernel and some
partition like Squashfs or JFFS2. This is pretty flexible solution, CFE
(the bootloader) just writes (and later boots) TRX at some hardcoded
place and paritions can vary in the size.
However some devices don't use TRX format. Very recently we have
discovered ZTE H218N that has kernel and rootfs partitions at some
"random" places.
This patch allows Linux find a rootfs partition after installing custom
image with a CFE bootloader.

Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
requires initialization. We already have code for this, but because
of the typo in code it was never working. This resulted in network not
working for some routers and possibility of soft-bricking them.
Use correct bit for switch initialization and fix typo in the define.

The Linksys wrt310n v1 does not have a robo_reset config variable in

switch, Linksys hard coded it into their source code.

This patch adds board detection for the Linksys E1000 V2.1 router, as well
as GPIO support for same.
This fixes bug #14135. Currently, wired networking isn't working on the
router, and I haven't tried the wireless, but with this patch, OpenWRT
successfully boots, and all the LEDs and buttons work properly.

The skb is usually started by a padding which allows the protocols in the
network stack to add their headers in front of the payload. The skb can be
reallocated in case the preallocated padding is not large enough. This can for
example happen in the function __skb_cow which will check the requested extra
headroom and allocate more buffer when the requested headroom is bigger than
the available one. The extra buffer is aligned again to the multiple of the
NET_SKB_PAD of the target architecture.
The macro used to create the multiple of the NET_SKB_PAD is written in a way
which allows only values power two as alignment parameter. The currently used
value of 48 bytes can not be written as n ** 2 but as 2 ** 4 + 2 ** 5. The
extra buffer is therefore not always the multiple of 48 but can be 16, 64, 80,
128, 144 and so on. The generated values are also not monotonic (48 requested
bytes are mapped to 80 allocated bytes and 49 requested bytes are mapped to 64
allocated bytes).
These unexpected small values result in more reallocations of the buffer. This
was noticed prominently during tests between two QCA9558 720 MHz devices which
were connected via ethernet to PCs and had a HT40 802.11n 3x3 link between each
other. The throughput PC-to-PC during iperf TCP runs increased reliable from
186 Mibit/s to 214 Mibit/s in one direction and from 195 Mibit/s to 220 Mibit/s
in the other direction. This is a performance increase of ~14% just by reducing
the amount of reallocations.
