[U-Boot] [PATCH 1/3] mmc: sdhci: increase the timeout value for data transfer

[Jaehoon Chung <jh80.chung@samsung.com>]

Hi Rommel,

I didn't think so..Our environment is support the CONFIG_SYS_MMC_MAX_BLK_COUNT.
Did you know how get the timeout value "1000"?

If the timeout value "1000" is reasonable, i want to know what basis.
Well, i don't think that my timeout value is reasonable.

Actually i want to remove the timeout value in that function.
But then we should be prevent the infinite loop.

Anyway, thanks for your comment. I will check the your opinion.

Best Regards,
Jaehoon Chung
