| /* |
| * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the |
| * stack that meets the minimum architecture alignment requirements for DMA. |
| * 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. |
