We use DMA on i.MX.

Hi, Fleming and Fabio
Sorry to reply to you so late.
As our manual described.
In the eSDHC, the data buffer can hold up to 128 words (32-bit).
The watermark levels for both write and read can be configured for CPU polling
mode.
The watermark level can be from 1 word to the maximum of 128 words

Yes, the offending commit is in master, but not on u-boot-imx branch.

Since commit 48e0b2bd (powerpc/esdhc: Correct judgement for DATA PIO mode)
we see mx6 systems to hang after doing a 'save' command.
Revert this commit since the original 'ifdef' logic from 7b43db92
(drivers/mmc/fsl_esdhc.c: fix compiler warnings) was the correct one.
