* kernel: mtdsplit: calculate kernel partition precisely for SeamaRafał Miłecki2016-06-201-2/+2
| | | | | | | | | So far "kernel" partition didn't contain just a kernel. It also included Seama header and meta data. This was making kernel update complex and it wasn't trivial to read kernel size. Fix it by making "kernel" parition contain just a kernel image. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

* kernel: mtdsplit: support uimage with UBIRafał Miłecki2016-02-241-3/+7
| | | | | | | | This patch adds uimage firmware split support for ubi. Signed-off-by: YounJae Rho <luxflow@live.com> SVN-Revision: 48755
* kernel: mtdsplit: add missing digest field to Seama headerRafał Miłecki2016-02-231-0/+1
| | | | | | | | | | | | | | | | | | | Seama format has 2 similar headers: container (seal) header and entity header. The first one has size always set to 0 and doesn't contain MD5 digest. When dealing with Seama on a flash we deal directly with an entity. You can see mtdsplit_parse_seama reads from offset 0 and expects entity to be there. Seama container is used by bootloader / interface only which extract entity out of it and flash it. That said we should fix our header struct. This is important as we calculate possible rootfs offset assuming it may be placed right after Seama entity. So far calculate offset was always 16B too low.

* kernel: mtdsplit: support Seama entity with UBIRafał Miłecki2016-02-012-3/+8
| | | | | | | | | | Some D-Link routers (e.g. DIR-885L) have NAND and use Seama format. It means OpenWrt will want to have UBI in Sseama entity and should be able to detect it. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48600
* kernel: mtdsplit: detect UBI partition when looking for rootfsRafał Miłecki2016-02-012-0/+7
| | | | | | | | | This allows mtdsplit parsers work with UBI which is very popular on NAND flases. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48599
* kernel: mtdsplit: modify rootfs helpers to provide partition typeRafał Miłecki2016-02-019-26/+42
| | | | | | | | | | Our mtdsplit parsers may want to create partition with name choice based on partition file system (e.g. SquashFS vs. JFFS2). This patch allows passing extra argument pointing to variable that will be set properly. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48598
* kernel: mtdsplit: document Seama splitter a bitRafał Miłecki2016-01-251-8/+10
| | | | | | | | | | Rename kernel_size variable as it includes whole entity size, not just a kernel size. Also update comments to match it and describe better what are we checking/looking for. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48480
* ar71xx: add support for Netgear WPN824NJohn Crispin2016-01-191-0/+2
| | | | | | | | | | | | | | | | Add support for Netgear WPN824N. Hardware specs: * AR7240, 4 LAN ports, 1 WAN port * AR9285 WLAN * 32 MB RAM * 4 MB Flash * 16 LEDs (LAN, WAN and Power/Status contain two LEDs for dual color effect) * 3 Buttons (not supported) Signed-off-by: Hartmut Knaack <knaack.h@gmx.de> SVN-Revision: 48356
* kernel: mtdsplit_squashfs: Align with the erase-block sizeFelix Fietkau2016-01-171-1/+1
| | | | | | | | | | | | | | On most image types the rootfs ends at an erase-block. However, at least with brnImages this is not the case: while the partitions are aligned with the erase-block size there is a 12 byte footer at the end of the partition which must not be touched by any filesystem. This lead to a rootfs_data partition which was not aligned properly (and thus ended up being readonly): 0x000000480000-0x00000085a800 : "rootfs_data" (128 KiB EB) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48263
* kernel: mtdsplit: add support for EVA imagesFelix Fietkau2016-01-173-0/+102
| | | | | | | | | This allows splitting EVA images (usually found in fritz devices). The firmware will be split into a kernel and a separate rootfs partition. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48262
* kernel: mtdsplit: add support for brnImagesFelix Fietkau2016-01-173-0/+110
| | | | | | | | | | | | | | | | | This adds brnImage (used with the brnboot bootloader) firmware parsing support. brnboot verifies the integrity of the firmware stored on the "Code Image" partitions by looking at the 12 byte footer at the very end of the partition. This footer contains the checksum of the original brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2 rootfs_data - otherwise the image will not be bootable anymore). Big thanks to Mathias Kresin for analyzing the brnImage structure and finding out the information how to keep images valid even when adding a nested rootfs_data partition.

* kernel: mtdsplit: add support for FIT imageJohn Crispin2015-03-153-0/+146
| | | | | | | | | | | If this option is enabled, the FIT image format will be detected and split by the mtdsplit code. Detection is based upon the FDT magic, which will trigger the parsing and detection of the rootfs, ending-up in the creation of the 2 new partitions.

* kernel: mtdsplit_uimage: fix passed info about buf sizeRafał Miłecki2015-02-121-2/+2
| | | | | | | | We obviously can't use sizeof(*buf) which is always 1. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 44424
* kernel: mtdsplit_uimage: read more data to match Edimax needsRafał Miłecki2015-02-121-8/+12

* kernel: mtdsplit_uimage: use separated buffer for reading dataRafał Miłecki2015-02-121-18/+16
| | | | | | | | | We shouldn't read data directly into the header struct, as some devices (e.g. Edimax) need more bytes due to some extra header. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 44414
* kernel: mtdsplit_uimage: add parser for Edimax devicesRafał Miłecki2015-02-121-0/+53

* mtdsplit_uimage: more generic header verify functionRafał Miłecki2015-02-121-11/+26
| | | | | | | | | | Some devices have uImage headers after some extra headers (e.g. Edimax devices). To support such cases our verify callback function should be allowed to return header offset, not just a boolean value. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 44412
* ar71xx: add Netgear WNR1000v2/WNR1000v2-VC support (#18633)John Crispin2015-01-301-0/+4
| | | | | | | | | | | The board is already supported by OpenWrt. WNR1000v2/WNR1000v2-VC are pretty much the same as WNR2000v3/WNR612v2, therefore the same initialization code and flash layout is used.

* kernel: add own Kconfig for OpenWrt mtdsplit driversJohn Crispin2014-08-251-0/+24
| | | | | | | | | | | | | There are pretty many OpenWrt patches against mtd subsystem resulting in a bit of mess and growing maintenance cost. My idea is to use an extra "mtdsplit" directory with OpenWrt specific files (including Kconfig). This is the first step to achieve this. This patch adds a "mtdsplit" directory with Kconfig and replaces 4 patches with a single one. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 42287
* kernel/generic: modify mtd related patches for 3.14Hauke Mehrtens2014-05-085-25/+19
| | | | | | | | | | | | | | | | | Function register_mtd_parser always returned 0 (at least since v3.3) before being changed to return void in v3.14-rc1~65^2~93 (mtd: make register_mtd_parser return void), so it's not needed to check the return value of this function. Also add __init flag to caller. This fix compile errors in 3.14 kernel like: drivers/mtd/mtdsplit_seama.c: In function 'mtdsplit_seama_init': drivers/mtd/mtdsplit_seama.c:99:2: error: void value not ignored as it ought to be return register_mtd_parser(&mtdsplit_seama_parser); ^ Signed-off-by: Zhao, Gang <gamerh2o@gmail.com> SVN-Revision: 40731

| | | | | | | | | | | | | | | This reverts r38197. The automatically created firmware partition includes the partition_table partition. Apart from the partition table, this partition contains sensitive data on some Compex devices which data can be destroyed when the firmware partition gets modified. Revert the change to prevent that.
