This trivial patch changes memcpy_(to|from)io as to transfer as many 32-bit words as possible in 32-bit accesses (in the current solution, the last 32-bit word was transferred as 4 byte accesses). Signed-off-by: Albrecht Dreß <redacted>
Besides the discussion about optimizing the loop, what about the patch itself? Looks plausible to me... -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
