The network components of a computer can be divided into two parts: hard
exactly corresponds to the three layers of the MMC/SD Driver (here we will look at the division of layers. Here we have a concept. When we finish the analysis, we will look back at it, and you will find it very vivid) (1) The block layer implements a card-based block Device Driver Based on the framework of the Linux block device

The interface between the client driver and the SD client driver allows the client driver to communicate with the
