Use __image_copy_end instead of __bss_start for the end of the image to
relocate. This is the same as commit 033ca72, but applied to all ARM start.S.
This is a more appropriate symbol naming for an image copy & relocate feature,
and this also saves a useless copy of data put between __image_copy_end and
__bss_start in linker scripts (e.g. relocation information, or MMU
initialization tables used only before jumping to the relocated image).

In the current u-boot, the device pin multiplexing and clock
initialisation needs to be early during the boot process and before
board_init() is called. U-boot is currently crashing on this board
because this is not being done early enough. Therefore, add a s_init()
function for the omap5912-osk board to do this.
Also fix the stack pointer so that it is pointing to the end of the
internal RAM and not the beginning as this was also causing the device
to crash.

The omap5912-osk board is using a RAM based address as the linker

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the

board/freescale/mx6qsabrelite/README explain a procedure to
update the SPI-NOR on the SabreLite board without Freescale
manufacturing tool but following this procedure leads to both
"sf erase" and "sf write" failing on a mx6qsabrelite board:
MX6QSABRELITE U-Boot > sf probe 1
MX6QSABRELITE U-Boot > sf erase 0 0x40000
SPI flash erase failed
MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000
SPI flash write failed
This is because the chip-select 1 is wrong and the correct
value is 0x7300.
Since commit c1173bd0 ("sf command: allow default bus and chip selects")
the chip-select and bus arguments for the sf probe command are optional
so let's just remove it and use "sf probe" instead.

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.

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
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.
It is tested with a MMCplus card.
