Mateusz Kijowski 1751f5ac7b drivers/sdcard: Do not release CS during the middle of read operations. It seems that some cards do not tolerate releasing the card (by setting CS high) after issuing CMD17 (and 18) and raising it again before reading data. Somehow this causes the 0xfe data start marker not being read and SDCard.readinto() is spinning forever (or until this byte is in the data). This seems to fix weird behviour of SDCard.readblocks() returning different data, also solved hanging os.mount() for my case with a 16GB Infineon card.
