BLOW OEM optional. If this bit is '0': FORCE_USB_BOOT GPIO when high during boot up; forces boot from USB. If this bit is '1': it disables this feature and FORCE_USB_BOOT GPIO works as a standard GPIO. 0x1 3 These fuses are used by boot code to specify which device has priority to be booted from. For SDx55, the mapping is as follows: 0x0:DEFAULT (Default (NAND-> USB)) 0x1: PCIE (PCIE) 0x2: USB (USB) 0x3: EMMC_USB 0x0 7:5 This fuse permanently disables root of trust transfer. 0x1 20 Shared QSEE Secure Non-invasive Debug Disable bucket. This OEM controlled fuse can be overriden by the corresponding QC fuse. 0x1 31 Shared MSS Invasive Debug Disable bucket. This OEM controlled fuse can be overriden by the corresponding QC fuse. 0x1 32 Shared MSS Non-invasive Debug Disable bucket. This OEM controlled fuse can be overriden by the corresponding QC fuse. 0x1 33 Shared CP Invasive Debug Disable bucket.
