1config MTD_PARSER_IMAGETAG

3	depends on BCM63XX || BMIPS_GENERIC || COMPILE_TEST
4	select CRC32
5	help
6	  Image Tag is the firmware header used by broadcom on their xDSL line
7	  of devices. It is used to describe the offsets and lengths of kernel
8	  and rootfs partitions.
9	  This driver adds support for parsing a partition with an Image Tag
10	  header and creates up to two partitions, kernel and rootfs.

12config MTD_AFS_PARTS
13	tristate "ARM Firmware Suite partition parsing"
14	depends on (ARM || ARM64)
15	help
16	  The ARM Firmware Suite allows the user to divide flash devices into
17	  multiple 'images'. Each such image has a header containing its name
18	  and offset/size etc.
19
20	  If you need code which can detect and parse these tables, and
21	  register MTD 'partitions' corresponding to each image detected,
22	  enable this option.
23
24	  You will still need the parsing functions to be called by the driver
25	  for your particular device. It won't happen automatically. The
26	  'physmap' map driver (CONFIG_MTD_PHYSMAP) does this, for example.
27
28config MTD_PARSER_TRX
29	tristate "Parser for TRX format partitions"
30	depends on MTD && (BCM47XX || ARCH_BCM_5301X || COMPILE_TEST)
31	help
32	  TRX is a firmware format used by Broadcom on their devices. It
33	  may contain up to 3/4 partitions (depending on the version).
34	  This driver will parse TRX header and report at least two partitions:
35	  kernel and rootfs.
36
37config MTD_SHARPSL_PARTS
38	tristate "Sharp SL Series NAND flash partition parser"
39	depends on MTD_NAND_SHARPSL || MTD_NAND_TMIO || COMPILE_TEST
40	help
41	  This provides the read-only FTL logic necessary to read the partition
42	  table from the NAND flash of Sharp SL Series (Zaurus) and the MTD
43	  partition parser using this code.
44
45config MTD_REDBOOT_PARTS
46	tristate "RedBoot partition table parsing"
47	help
48	  RedBoot is a ROM monitor and bootloader which deals with multiple
49	  'images' in flash devices by putting a table one of the erase
50	  blocks on the device, similar to a partition table, which gives
51	  the offsets, lengths and names of all the images stored in the
52	  flash.
53
54	  If you need code which can detect and parse this table, and register
55	  MTD 'partitions' corresponding to each image in the table, enable
56	  this option.
57
58	  You will still need the parsing functions to be called by the driver
59	  for your particular device. It won't happen automatically. The
60	  SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
61	  example.

65config MTD_REDBOOT_DIRECTORY_BLOCK
66	int "Location of RedBoot partition table"
67	default "-1"
68	help
69	  This option is the Linux counterpart to the
70	  CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time
71	  option.
72
73	  The option specifies which Flash sectors holds the RedBoot
74	  partition table.  A zero or positive value gives an absolute
75	  erase block number. A negative value specifies a number of
76	  sectors before the end of the device.
77
78	  For example "2" means block number 2, "-1" means the last
79	  block and "-2" means the penultimate block.
80
81config MTD_REDBOOT_PARTS_UNALLOCATED
82	bool "Include unallocated flash regions"
83	help
84	  If you need to register each unallocated flash region as a MTD
85	  'partition', enable this option.
86
87config MTD_REDBOOT_PARTS_READONLY
88	bool "Force read-only for RedBoot system images"
89	help
90	  If you need to force read-only for 'RedBoot', 'RedBoot Config' and
91	  'FIS directory' images, enable this option.
