Linux kernel 2.6.7 on h8300. CONFIG_MTD_BLOCK: Although most flash chips have an erase size too large to be useful as block devices, it is possible to use MTD devices which are based on RAM chips in this manner. This block device is a user of MTD devices performing that function. At the moment, it is also required for the Journalling Flash File System(s) to obtain a handle on the MTD device when it's mounted (although JFFS and JFFS2 don't actually use any of the functionality of the mtdblock device). Later, it may be extended to perform read/erase/modify/write cycles on flash chips to emulate a smaller block size. Needless to say, this is very unsafe, but could be useful for file systems which are almost never written to. You do not need this option for use with the DiskOnChip devices. For those, enable NFTL support (CONFIG_NFTL) instead. See this item in context Full configuration for 2.6.7 on h8300 Home   Search
