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 current driver uses the IIF bit in the status register

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

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.

symlink. Update cleanup code accordingly.

the environment properly setup. This causes issues because of the
numerous ways the environment might be accessed because of the
non-volatile memory it might be stored in. Additionally the access
might be so early that memory isn't even properly setup for us.
Towards resolving these issues we provide versions of all the hwconfig
APIs that can be passed in a buffer to parse and leave it to the caller
to determine how to allocate and populate the buffer.
We use the _f naming convention for these new APIs even though they are
perfectly useable after relocation and the environment being ready.
We also now warn if the non-f APIs are called before the environment is
ready to allow users to address the issues.
