[U-Boot] [PATCH v2 1/3] mmc: Read sd card detect properties from DT

[Suniel Mahesh]

Hi Marek,

Looks like CD is working fine with TI AM3358X SOC based targets.

Ran a quick test after looking at the discussion, posting the results which might be of some help.

In this test, mmc part is not printing the partition table of the previous card, instead it prints
the partition table of the latest card which is inserted.

Hope the test is inline with the discussion. Please ignore if the results doesn't make any sense.

Tested on U-Boot v2019.07-rc1

8GB card inserted

=> mmc rescan
=> mmc part
