PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.
By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

Commit 3ebd1cbc introduced compiler-generated __bss_start

as __bss_end. Their merge caused silent and harmless but

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.

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes

well as after.
Note: this affects more than ARM targets, as linker-
