It is used to describe the offsets and lengths of kernel 9 and rootfs partitions. 10 This driver adds support for parsing a partition with an Image Tag 11 header and creates up to two partitions, kernel and rootfs. 12 13config MTD_AFS_PARTS 14 tristate "ARM Firmware Suite partition parsing" 15 depends on (ARM || ARM64) 16 help 17 The ARM Firmware Suite allows the user to divide flash devices into 18 multiple 'images'. Each such image has a header containing its name 19 and offset/size etc. 20 21 If you need code which can detect and parse these tables, and 22 register MTD 'partitions' corresponding to each image detected, 23 enable this option. 24 25 You will still need the parsing functions to be called by the driver 26 for your particular device. It won't happen automatically. The 27 'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example. 28 29config MTD_PARSER_TRX 30 tristate "Parser for TRX format partitions" 31 depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST) 32 help 33 TRX is a firmware format used by Broadcom on their devices. It 34 may contain up to 3/4 partitions (depending on the version). 35 This driver will parse TRX header and report at least two partitions: 36 kernel and rootfs. 37 38config MTD_SHARPSL_PARTS 39 tristate "Sharp SL Series NAND flash partition parser" 40 depends on MTD_NAND_SHARPSL || MTD_NAND_TMIO || COMPILE_TEST 41 help 42 This provides the read-only FTL logic necessary to read the partition 43 table from the NAND flash of Sharp SL Series (Zaurus) and the MTD 44 partition parser using this code. 45 46config MTD_REDBOOT_PARTS 47 tristate "RedBoot partition table parsing" 48 help 49 RedBoot is a ROM monitor and bootloader which deals with multiple 50 'images' in flash devices by putting a table one of the erase 51 blocks on the device, similar to a partition table, which gives 52 the offsets, lengths and names of all the images stored in the 53 flash. 54 55 If you need code which can detect and parse this table, and register 56 MTD 'partitions' corresponding to each image in the table, enable 57 this option. 58 59 You will still need the parsing functions to be called by the driver 60 for your particular device. It won't happen automatically. The 61 SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for 62 example. 63 64if MTD_REDBOOT_PARTS 65 66config MTD_REDBOOT_DIRECTORY_BLOCK 67 int "Location of RedBoot partition table" 68 default "-1" 69 help 70 This option is the Linux counterpart to the 71 CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time 72 option. 73 74 The option specifies which Flash sectors holds the RedBoot 75 partition table. A zero or positive value gives an absolute 76 erase block number. A negative value specifies a number of 77 sectors before the end of the device. 78 79 For example "2" means block number 2, "-1" means the last 80 block and "-2" means the penultimate block. 81 82config MTD_REDBOOT_PARTS_UNALLOCATED 83 bool "Include unallocated flash regions" 84 help 85 If you need to register each unallocated flash region as a MTD 86 'partition', enable this option. 87 88config MTD_REDBOOT_PARTS_READONLY 89 bool "Force read-only for RedBoot system images" 90 help 91 If you need to force read-only for 'RedBoot', 'RedBoot Config' and 92 'FIS directory' images, enable this option. 93 94endif # MTD_REDBOOT_PARTS 95
