今天调通了2.6.32上mpc8313e的mini sd卡驱动,灰常开心,记录仅仅供自己回忆参考
官方rdb板用的是SD卡,
MPC8313e RDB SD Memory Card Interface
An SD memory card interface connects directly to the SPI bus of the MPC8313E. SD data mode and SDIOmode are not supported. The SPI mode is the only SD operating mode supported by this connection. Hot insertion and removal is not supported. See Figure 12 for the hardware connection.For REVB boards, the SD card chip select signal is changed from GPIO31(SPISEL) to GPIO13(LA8)because when using SPI as master mode, SPISEL can not be set as GPIO (which supposed to be used for device select signal). In this case, another GPIO pin (GPIO13) should be used but not the SPISEL.
