Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

The on-board number of available usdhc devices is something board
specific. The patch moves CONFIG_SYS_FSL_USDHC_NUM out of
mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd
board.
To keep the default mmc device for environment same as before (usdhc3),
it moves CONFIG_SYS_MMC_ENV_DEV out of mx6qsabre_common.h and changes
it to 1 for mx6qsabresd.

This patch builds upon the recently introduced CBMEM console
feature of coreboot.
CBMEM console uses a memry area allocated by coreboot to store
the console output. The memory area has a certain structure,
which allows to determine where the buffer is, the buffer size
and the location of the pointer in the buffer. This allows
different phases of the firmware (rom based coreboot, ram based
coreboot, u-boot after relocation with this change) to keep
adding text to the same buffer.
Note that this patch introduces a new console driver and adds the
driver to the list of drivers to be used for console output, i.e.
it engages only after u-boot relocates. Usiong CBMEM console for
capturing the pre-relocation console output will be done under a
separate change.
>From Linux, run the cbmem.py utility (which is a part of the coreboot
package) to see the output, e.g.:
vvvvvvvvvvvvvvvvv
SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode
flags: 64bit ilck stag led pmp pio
...
Magic signature found
Kernel command line: "cros_secure quiet loglevel=1 console=tty2...
^^^^^^^^^^^^^^^^^
Note that the entire u-boot output fits into the buffer only if
the coreboot log level is reduced from the most verbose. Ether
the buffer size will have to be increased, or the coreboot
verbosity permanently reduced.

Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In
some cases (e.g. user load commands) this cannot be guaranteed by callers
of the MMC APIs. To solve this, modify the Tegra MMC driver to use the
new bounce_buffer_*() APIs.
Note: Ideally, all U-Boot code will always provide address- and size-
aligned buffers, so a bounce buffer will only ever be needed for user-
supplied buffers (e.g. load commands). Ensuring this removes the need
for performance-sucking bounce buffer cache management and memcpy()s.
The one known exception at present is the SCR buffer in sd_change_freq(),
which is only 8 bytes long. Solving this requires enhancing struct
mmc_data to know the difference between buffer size and transferred data
size, or forcing all callers of mmc_send_cmd() to have allocated buffers
using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not
enforced in any way at present, and so cannot be assumed by the core MMC
code.

The current bouncebuf API requires all parameters to be passed to both
bounce_buffer_start() and bounce_buffer_stop(). Modify the bouncebuf
start function to accept a state structure as a parameter, and only
require that state struct to be passed to the stop function. This
simplifies usage of the bounce buffer by clients.
Don't modify the data pointer, but rather store the temporary buffer in
this state struct. The bouncebuf code ensures that client code can
always use a single buffer pointer in the state structure, irrespective
of whether a bounce buffer actually had to be allocated.
Move cache management logic into the bounce buffer code, so that each
client doesn't have to duplicate this. I believe there's no need to
invalidate the buffer before a DMA operation, since flushing the cache
should prevent any write-backs.
Update the MXS MMC driver for this change.
