- * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the

- * Such a buffer is useful for DMA operations where flushing and invalidating
- * the cache before and after a read and/or write operation is required for
- * correct operations.
- *
- * When called the macro creates an array on the stack that is sized such
- * that:
- *
- * 1) The beginning of the array can be advanced enough to be aligned.
- *
- * 2) The size of the aligned portion of the array is a multiple of the minimum
- * architecture alignment required for DMA.
- *
- * 3) The aligned portion contains enough space for the original number of
- * elements requested.
- *
- * The macro then creates a pointer to the aligned portion of this array and
- * assigns to the pointer the address of the first element in the aligned
- * portion of the array.
- *
- * Calling the macro as:
- *
- * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
- *
- * Will result in something similar to saying:
- *
- * uint32_t buffer[1024];
- *
- * The following differences exist:
- *
- * 1) The resulting buffer is guaranteed to be aligned to the value of
- * ARCH_DMA_MINALIGN.
- *
- * 2) The buffer variable created by the macro is a pointer to the specified
- * type, and NOT an array of the specified type. This can be very important
- * if you want the address of the buffer, which you probably do, to pass it
- * to the DMA hardware. The value of &buffer is different in the two cases.
- * In the macro case it will be the address of the pointer, not the address
- * of the space reserved for the buffer. However, in the second case it
- * would be the address of the buffer. So if you are replacing hard coded
- * stack buffers with this macro you need to make sure you remove the & from
- * the locations where you are taking the address of the buffer.
- *
- * Note that the size parameter is the number of array elements to allocate,
- * not the number of bytes.
- *
- * This macro can not be used outside of function scope, or for the creation
- * of a function scoped static buffer. It can not be used to create a cache
- * line aligned global buffer.
