在probe 函数中,我们需要为三个与MTD 相关的结构体分配内存以及初始化,它们是struct mtd_info 、struct mtd_partition 和struct nand_chip 。其中前两者已经在四节做过说明,这里只对struct nand_chip 做一些介绍。struct nand_chip 是一个与NAND 芯片密切相关的结构体,主要包含三方面内容: A)指向

nand_info[] is now an array of pointers, with the actual mtd_info instance embedded in struct nand_chip. This is in preparation for syncing the NAND code with Linux 4.6, which makes the same change to struct nand_chip. It's in a separate commit due to the large amount of changes req...

NAND Flash chip, the impedance mismatch between the controller and the signal transmission channel of NAND Flash can be minimized, which helps to reduce the signal reflection. In addition, the ODT resistance value can be controlled from software configuration register, thus greatly simplifying the ...
