ARM: Avoid compiler optimization for readb, writeb and friends.
gcc 4.5.1 seems to ignore (at least some) volatile definitions,
avoid that as done in the kernel.
Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that
gcc version to ignore the volatile type qualifier used e.g. in __arch_getl().
Anyway, using a definition as in the kernel headers avoids such optimizations when
gcc 4.5.1 is used.
Maybe the headers as used in the current linux-kernel should be used,
but to avoid large changes, I've just added a small change to the current headers.

The MXC SPI driver didn't calculate the SPI clock up to

data, so not all data scheduled for transmition is actually
transmited.

I2C: mxc_i2c: address failure with mx35 processor
There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).
The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.
This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.
The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().

Don't add symlink in srctree when using an objtree
When building with srctree != objtree, the build creates arch/soc/cpu
specific symlinks in the source tree. This means that the same source
tree can't be used for multiple builds at the same time. Also, these
symlinks in the source tree are only cleaned up if one passes the same
O= to distclean.
When srctree != objtree, mkconfig creates an $objtree/include2 directory
in the objtree to host the asm -> arch/$arch/include/asm symlink so that
"#include <asm>" can be used. But it also creates another identical
symlink in $objtree/include.
Then, mkconfig creates two symlinks:
$objtree/include/asm/arch -> arch/$arch/include/asm/arch-$cpu (or $soc)
$objtree/include/asm/proc -> arch/$arch/include/asm/proc-armv (on arm)
but because $objtree/include/asm points at $srctree already, the two
symlinks are created under $srctree.
To fix this, create a real $objtree/include/asm directory, instead of a
symlink. Update cleanup code accordingly.
