Re: [U-Boot] [PATCH] mmc: dw_mmc: fix timeout calculate method

Subject: [PATCH] mmc: dw_mmc: fix timeout calculate method

There are two cases not been considered:

• use uint for timeout, it will overflow when size bigger than 512KB for it *8*1000 at the beginning, but we may use size up to 32MB;
• The timeout is using clock speed for data rate, but the device may not have such high speed, eg. clock is 52MHz while the device write speed may be less than 10MB/s.

Fix them in this patch, the max timeout is about 6500 when size is 32MB after fix.
