A Brief History of THz Imaging Potentials and Limitations. Defect Detection via THz Imaging:

CFI is enabled via the kernel-configuration utility under the Memory Technology Devices (MTD) top-level menu. Select Detect flash chips by Common Flash Interface (CFI) probe under RAM/ROM/Flash chip drivers, as illustrated in Figure 10-3. Figure 10-3. Kernel configuration for MTD CFI support As shown in Listing 10-6, the Flash chip is detected via the CFI interface. Because we also enabled CONFIG_MTD_REDBOOT_PARTS (see Figure 10-2), MTD scans for the Redboot partition table on the Flash chip. Notice also that the chip has been enumerated with the device name IXP4XX-Flash0. You can see from Listing 10-6 that the Linux kernel has detected three partitions on the Flash chip, as enumerated previously using the fis list command in Redboot. When the infrastructure is in place as described here, the Linux kernel automatically detects and creates kernel data structures representing the three Flash partitions. Evidence of these can be found in the /proc file system when the kernel has completed initialization, as shown in Listing 10-7. Listing 10-7 ...»
