+* Invalidate the Data cache for the given address range.
+* If the bytes specified by the address (adr) are cached by the Data cache,
+* the cacheline containing that byte is invalidated.	If the cacheline
+* is modified (dirty), the modified contents are lost and are NOT
+* written to system memory before the line is invalidated.
+*
+* In this function, if start address or end address is not aligned to cache-line,
+* particular cache-line containing unaligned start or end address is flush first
+* and then invalidated the others as invalidating the same unaligned cache line
+* may result into loss of data. This issue raises few possibilities.
+*
+*
+* If the address to be invalidated is not cache-line aligned, the
+* following choices are available:
+* 1) Invalidate the cache line when required and do not bother much for the
+* side effects. Though it sounds good, it can result in hard-to-debug issues.
+* The problem is, if some other variable are allocated in the
+* same cache line and had been recently updated (in cache), the invalidation
+* would result in loss of data.
+*
+* 2) Flush the cache line first. This will ensure that if any other variable
+* present in the same cache line and updated recently are flushed out to memory.
+* Then it can safely be invalidated. Again it sounds good, but this can result
+* in issues. For example, when the invalidation happens
+* in a typical ISR (after a DMA transfer has updated the memory), then flushing
+* the cache line means, loosing data that were updated recently before the ISR
+* got invoked.
+*
+* Linux prefers the second one. To have uniform implementation (across standalone
+* and Linux), the second option is implemented.
+* This being the case, follwoing needs to be taken care of:
+* 1) Whenever possible, the addresses must be cache line aligned. Please nore that,
+* not just start address, even the end address must be cache line aligned. If that
+* is taken care of, this will always work.
+* 2) Avoid situations where invalidation has to be done after the data is updated by
+* peripheral/DMA directly into the memory. It is not tough to achieve (may be a bit
+* risky). The common use case to do invalidation is when a DMA happens. Generally
+* for such use cases, buffers can be allocated first and then start the DMA. The
+* practice that needs to be followed here is, immediately after buffer allocation
+* and before starting the DMA, do the invalidation. With this approach, invalidation
+* need not to be done after the DMA transfer is over.
+*
+* This is going to always work if done carefully.
+* However, the concern is, there is no guarantee that invalidate has not needed to be
+* done after DMA is complete. For example, because of some reasons if the first cache
+* line or last cache line (assuming the buffer in question comprises of multiple cache
+* lines) are brought into cache (between the time it is invalidated and DMA completes)
+* because of some speculative prefetching or reading data for a variable present
+* in the same cache line, then we will have to invalidate the cache after DMA is complete.
+*
+*
+* @param	Start address of range to be invalidated.
+* @param	Length of range to be invalidated in bytes.
+*
+* @return	None.
