- * FTMAC110 DMA design issue
- *
- * Its DMA engine has a weird restriction that its Rx DMA engine
- * accepts only 16-bits aligned address, 32-bits aligned is not
- * acceptable. However this restriction does not apply to Tx DMA.
- *
- * Conclusion:
- * (1) Tx DMA Buffer Address:
- *     1 bytes aligned: Invalid
- *     2 bytes aligned: O.K
- *     4 bytes aligned: O.K (-> u-boot ZeroCopy is possible)
- * (2) Rx DMA Buffer Address:
- *     1 bytes aligned: Invalid
- *     2 bytes aligned: O.K
