mx6: Fix get_board_rev() for the mx6 solo case
When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev()
returns 0x62xxx, which is not a value understood by the VPU
(Video Processing Unit) library in the kernel and causes the video playback to
fail.
The expected values for get_board_rev are:
0x63xxx: For mx6quad/dual
0x61xxx: For mx6dual-lite/solo
So adjust get_board_rev() accordingly and make it as weak function, so that we
do not need to define it in every mx6 board file.

mmc: i.MX6: fsl_esdhc: Define maximum bus width supported by a board
Maximum bus width supported by some i.MX6 boards is not 8bit like
others. In case where both host controller and card support 8bit transfers,
they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not

Now SDRAM initialization is done on the basis of omap revision.
Instead this should be done on basis of SDRAM type read from
EMIF_SDRAM_CONFIG register. This will be helpful to avoid
unnessecary cpu checks for new boards

am335x: cpsw: optimize cpsw_send to increase network performance
Before submitting packets to cpdma, phy status is updated on every packet
which leads to delay in packet send intern reduces the Ethernet performance.
Checking mdio status for each packet will reduce timetaken to send a packet
and there by increasing the Ethernet performance. With this the performance
is increased from 208KiB/s to 375KiB/s on EVMsk

omap4_common: Enable CONFIG_CMD_BOOTZ
With v3.9 and later of the Linux Kernel defaulting to multi-platform
images with omap2plus_defconfig, uImage isn't builtable anymore by
default. Add CONFIG_CMD_BOOTZ so that we can still boot something the
kernel spits out.
