Ensure that the view of memory from the CPU & the ethernet controller is
coherent at the various points where they exchange data. This prevents
stale data from being transmitted or received, and prevents the driver
from getting stuck waiting for the ethernet controller to update
descriptors when in reality it has but the old values are being read
from cache.

Netconsole loses the second character when used as input by
either setenv stdin nc or setenv stdin serial,nc if using CONSOLE_CONSOLE_MUX
Before a nc_send_packet() to echo the input, a check is done to see if
nc_ether is valid. If its not, it waits for an arp request and then sends
the packet (which contains the first character of line to be displayed as
output). As part of reaping the arp request, the second character is consumed.
We protect this by making the call to NetLoop(NETCONS) between
input_recursion.

This patch introduces some cleanups to ums code. Changes:
ums common:
- introduce UMS_START_SECTOR and UMS_NUM_SECTORS as defined in
usb_mass_storage.h both default values as 0 if board config
doesn't define them
common cleanup changes:
- change name of struct "ums_board_info" to "ums"
- "ums_device" fields are moved to struct ums and "dev_num" is removed
- change function name: board_ums_init to ums_init
- remove "extern" prefixes from usb_mass_storage.h
cmd_usb_mass_storage:
- change error() to printf() if need to print info message
- change return values to command_ret_t type at ums command code
- add command usage string
Changes v2:
ums common:
- always returns number of read/write sectors
- coding style clean-up

Old command timeout value was too small and it caused I/O errors which
led to uncompleted read/write/erase operations and filesystem errors.
Timeout adaptation fixes this issue.
Changes in sdhci_send_command() function:
- change timeout variable to static
- increase default command timeout to 100 ms
- add definition of max command timeout value,
which can be redefined in each board config file
- wait for card ready state for max defined time
if it doesn't exceed defined maximum or return COMM_ERR
Once successfully increased timeout value will be used in next function
call. This fix was tested on Goni, Trats, Trats2 boards by testing UMS
on MMC storage.
Changes v2:
- move global variable cmd_timeout into function sdhci_send_command()
- change condition "==" to ">=" when comparing time with timeout
- print information about timeout increasing and card busy timeout

Currently the HDMI splash screen image quality on mx6solo does not show a
very stable image.
By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.
>From FSL BSP [1] we have:
if (!sig.clk_pol)
di_gen |= DI_GEN_POLARITY_DISP_CLK;
Applying the same logic into U-boot fixes the HDMI image stability.
