This patch series replaces the custom bit manipulation function sr32()
by standard I/O accessors. A major motivation for this cleanup was
the fact that a number of calls of that function resulted in 32 bit
wide shift operations on u32 data, which according to the C-ISO
IEC-9899-Standard provokes undefined behaviour:
6.5.7 Bitwise shift operators
...
If the value of the right operand is negative or is
greater than or equal to the width of the promoted left
operand, the behavior is undefined.
The code was built-tested for all TI boards (using "./MAKEALL -v ti")
without errors or warnings.
