The STOP command can terminate a data transfer between a memory card and

As show in Synopsys DesignWare Cores Mobile Stroage Host Databook:
Data timeout and Data end-bit error will terminate further data transfer
by mmc controller. So we should not send abort command to terminate a
data transfer again if we got DRTO and EBE interrupt.

After this patch, all mmc_test cases can pass on RK3288-Pink2 board.

Changes in v2:
- DRTO and EBE are both set, should not send abort command too,

I also suggested that you change the subject to "mmc: dw_mmc: fix
mmc_test by not sending abort for DRTO / EBE errors" which you didn't
do.  ...I guess that's not critical.  Perhaps Jaehoon (who is
collecting patches for Ulf now I think) can adjust the subject when he
applies.

In any case, v2 fixes my problems and seems OK to me.
