Tested on S3C6410-based Mini6410 board, with following performance
figures:
* Before this series (133 MHz HCLK always selected, leading to at most
33 MHz card clock):
root@tiny6410:~# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 42 MB in 3.10 seconds = 13.54 MB/sec
# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 44 MB in 3.12 seconds = 14.11 MB/sec
/dev/mmcblk0:
Timing buffered disk reads: 38 MB in 3.14 seconds = 12.12 MB/sec
* After this series (48 MHz EPLL clock selected, leading to 48 MHz card
clock):
root@tiny6410:~# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 56 MB in 3.04 seconds = 18.41 MB/sec
# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 48 MB in 3.01 seconds = 15.94 MB/sec
/dev/mmcblk0:
Timing buffered disk reads: 56 MB in 3.05 seconds = 18.35 MB/sec
So on a s3c2416:
