[PATCH] IDE: Improving speed on reading data
This patch improves the speed when reading blocks from IDE devices by reading more than one block at a time. Up to 128 blocks are requested in one read command.
On my testplatform (Janz emPC-A400 with CompactFLASH card) this nearly doubled speed.
Also the ide_wait() code was rewritten to have lower latency by polling more frequently for status.
Can you please use git-format-patch to format the patch? I don't know how you created the diff, but it looks strange to me (and harldy readable).
The patch is against "latest" u-boot git-repository
Please (still) be patient if style of submission or patches are offending.
Such comments must go below the "---" line

ide_outb (device, ATA_SECT_CNT, 1);
scnt = (blkcnt > 128) ? 128 : blkcnt;ide_outb (device, ATA_SECT_CNT, scnt);
What happens if you try to read at or beyond the end of the device?
Best regards,
Wolfgang Denk
