It is used to describe the offsets and lengths of kernel 21 and rootfs partitions. 22 This driver adds support for parsing a partition with an Image Tag 23 header and creates up to two partitions, kernel and rootfs. 24 25config MTD_AFS_PARTS 26 tristate "ARM Firmware Suite partition parsing" 27 depends on (ARM || ARM64) 28 help 29 The ARM Firmware Suite allows the user to divide flash devices into 30 multiple 'images'. Each such image has a header containing its name 31 and offset/size etc. 32 33 If you need code which can detect and parse these tables, and 34 register MTD 'partitions' corresponding to each image detected, 35 enable this option. 36 37 You will still need the parsing functions to be called by the driver 38 for your particular device. It won't happen automatically. The 39 'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example. 40 41config MTD_PARSER_TRX 42 tristate "Parser for TRX format partitions" 43 depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST) 44 help 45 TRX is a firmware format used by Broadcom on their devices.

It won't happen automatically. The 73 SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for 74 example. 75 76if MTD_REDBOOT_PARTS 77 78config MTD_REDBOOT_DIRECTORY_BLOCK 79 int "Location of RedBoot partition table" 80 default "-1" 81 help 82 This option is the Linux counterpart to the 83 CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time 84 option. 85 86 The option specifies which Flash sectors holds the RedBoot 87 partition table. A zero or positive value gives an absolute 88 erase block number. A negative value specifies a number of 89 sectors before the end of the device. 90 91 For example "2" means block number 2, "-1" means the last 92 block and "-2" means the penultimate block. 93 94config MTD_REDBOOT_PARTS_UNALLOCATED 95 bool "Include unallocated flash regions" 96 help 97 If you need to register each unallocated flash region as a MTD 98 'partition', enable this option. 99 100config MTD_REDBOOT_PARTS_READONLY 101 bool "Force read-only for RedBoot system images" 102 help 103 If you need to force read-only for 'RedBoot', 'RedBoot Config' and 104 'FIS directory' images, enable this option. 105 106endif # MTD_REDBOOT_PARTS 107
