This extra pullup may cause problems in some special cases with some SD Cards. As example hama micro-SD Card when used with PS7 SDIO MIO pullups enabled and R43 loaded had sporadic initialization problems on TE0703, removing R43 solved the issue.

Note
Some other designs and boards that use TXS02612 may have pullup on CMD, this is incorrect as per TXS02612 datasheet. Xilinx ZC702 board that uses SDIO level shifter with similar technology includes the CMD pullup but has it marked "DNP" do not populate.
