MMC/SD Card driver for OMAP 35xx (SDIO not supported)\r
\r
This driver always produces a BlockIo protocol but it starts off with no Media\r
- present. A TimerCallBack detects when media is inserted or removed and after \r
- a media change event a call to BlockIo ReadBlocks/WriteBlocks will cause the \r
+ present. A TimerCallBack detects when media is inserted or removed and after\r
+ a media change event a call to BlockIo ReadBlocks/WriteBlocks will cause the\r
media to be detected (or removed) and the BlockIo Media structure will get\r
updated. No MMC/SD Card harward registers are updated until the first BlockIo\r
- ReadBlocks/WriteBlocks after media has been insterted (booting with a card \r
- plugged in counts as an insertion event). \r
