Hello Hao,


I have made all the changes as recommended and have submitted patch v7. I have completed all verification as suggested by you and it all seems to be working. I have also made changes for passing controller version through private structure.


Thanks

Ashish

For the file access issue on SD/eMMC devices, found that it is related with the
above change. Please update it to:

if (Remaining <= AdmaMaxDataPerLine) {

Otherwise, when the length of the last chunk of transfer equals to
'AdmaMaxDataPerLine', the proposed change will not break out of the 'for' loop.
This will lead to a value underflow of the variable 'Remaining', which will
further cause the file access failure.

Please update the above line to:

if (DataLength26) {

There are some similar cases below, please help to update them as well.

The above 2 statements seem not consistent with their counterparts under the
'else' part. Please help to refine one of them, thanks.

Same issue with the previous one.
