It is used to describe the offsets and lengths of kernel 14 and rootfs partitions. 15 This driver adds support for parsing a partition with an Image Tag 16 header and creates up to two partitions, kernel and rootfs. 17 18config MTD_AFS_PARTS 19 tristate "ARM Firmware Suite partition parsing" 20 depends on (ARM || ARM64) 21 help 22 The ARM Firmware Suite allows the user to divide flash devices into 23 multiple 'images'. Each such image has a header containing its name 24 and offset/size etc. 25 26 If you need code which can detect and parse these tables, and 27 register MTD 'partitions' corresponding to each image detected, 28 enable this option. 29 30 You will still need the parsing functions to be called by the driver 31 for your particular device. It won't happen automatically. The 32 'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example. 33 34config MTD_PARSER_TRX 35 tristate "Parser for TRX format partitions" 36 depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST) 37 help 38 TRX is a firmware format used by Broadcom on their devices.

It won't happen automatically. The 66 SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for 67 example. 68 69if MTD_REDBOOT_PARTS 70 71config MTD_REDBOOT_DIRECTORY_BLOCK 72 int "Location of RedBoot partition table" 73 default "-1" 74 help 75 This option is the Linux counterpart to the 76 CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time 77 option. 78 79 The option specifies which Flash sectors holds the RedBoot 80 partition table. A zero or positive value gives an absolute 81 erase block number. A negative value specifies a number of 82 sectors before the end of the device. 83 84 For example "2" means block number 2, "-1" means the last 85 block and "-2" means the penultimate block. 86 87config MTD_REDBOOT_PARTS_UNALLOCATED 88 bool "Include unallocated flash regions" 89 help 90 If you need to register each unallocated flash region as a MTD 91 'partition', enable this option. 92 93config MTD_REDBOOT_PARTS_READONLY 94 bool "Force read-only for RedBoot system images" 95 help 96 If you need to force read-only for 'RedBoot', 'RedBoot Config' and 97 'FIS directory' images, enable this option. 98 99endif # MTD_REDBOOT_PARTS 100
