In order to mx53 ROM to properly load the U-boot image, its header size should
be multiple of 512 bytes.
This issue was observed with gcc 4.6.2/4.7.3, which caused data aborts:

,and this patch fixes it.
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."

Make the error handling more robust.
Check if each one of the PMIC writes fail and if they do, just return
immediately.
Also, print the cause for the failures.

commit c73368150 (pmic: Extend PMIC framework to support multiple instances
of PMIC devices) introduced an extra 'retval' variable, but this is not
necessary since we have already the variable 'ret' in place.
So use 'ret' to store the return values from the pmic related calls and remove
'retval'.

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.

SPL doesn't write to the environment. These list entries prevent the
functions from being garbage-collected, even though nothing will look at
the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to
break due to size limitations and/or unresolved symbols.
A static inline function is used to provide a context in which we
can consume the callback, and thus avoid unused function warnings.

IFC_FIR_OP_CMD0 issues command for execution without checking flash
readiness. It may cause problem if flash is not ready. Instead use
IFC_FIR_OP_CW0 which Wait for tWB time and poll R/B to return high or

NAND_CMD_READID command implemention does not fulfill above requirement. So

It is useful to have a basic SPI flash test, which tests that the SPI chip,
the SPI bus and the driver are behaving.
This test erases part of the flash, writes data and reads it back as a
sanity check that all is well.

The current logic reads the port status just once after usb_hub_power_on and
expects the portstatus and portchange to report the connection status
immediately and correctly.
Few pen drives are not able to report both of them immediately ie. those pens
report the connection change but not the connected state after the first read.
This opportunity once lost is gone for ever because the u-boot, unlike linux or
any other OS, works in polling mode.
This patch modifies the logic to read the port status continuously until the
portstatus and portchange both report a connection change as well as a connected
state or no connection change and no connection. This logic is placed in a
timeout of 10 sec. At the end of it, the pen drive would have either reported a
ONE or a ZERO in bit 1 of portstatus as well as portchange.
It enhances the set of pen drives which can eventually be detected by u-boot
Note: This 10 second timeout is based purely on several experiments done with
the broken pen drives
