* kernel: mtd: bcm-wfi: add cferam name supportÁlvaro Fernández Rojas2023-06-151-2/+14
| | | | | | | | | Some devices rename cferam bootloader using specific patterns and don't follow broadcom standards for renaming cferam files. This requires supporting different cferam file names. Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com> (cherry picked from commit 8813edd8d9695d4e3939fdaa3c530c682f91de11)

* kernel: mtk_bmt: add support for the bbt format used on mt7621Felix Fietkau2022-01-131-6/+202
| | | | | | | | | This does not have spare blocks for remapping, and it is also not suitable for random write access. It only skips over bad blocks on linear writes of an image to a partition. As such, it is really only suitable for the kernel partition, or other partitions with mostly static data Signed-off-by: Felix Fietkau <nbd@nbd.name>

* kernel: mtdsplit_fit: support FIT with external dataDaniel Golle2021-04-091-39/+243
| | | | | | | | | | | | | | | | | | U-Boot has recently added support for having data blobs in uImage.FIT images stored at offsets after the FDT structure rather than embedding the data into the FDT structure itself. This is useful as it allows parts of the image to be mapped by the FIT partition parser, and it allows the FIT structure itself to be parsed more easily as it usually fits into single page. mtdsplit_fit assumed that the total length of an image is identical to the length of the FDT structure. For uImage.FIT with external data this assumption no longer holds true. Add support for uImage.FIT with external data to mtdsplit_fit and in in that case only split-off rootfs_data -- selecting and mapping rootfs partition is left to the block partition parser just like on UBI and block/GPT based platforms.

* kernel: create bootfs partition when parsing on BCM4908Rafał Miłecki2021-03-241-5/+9
| | | | | | | | It's helpful for accessing booting data (DTS, kernel, etc.). It has to be used carefully as CFE's JFFS2 support is quite dumb. It doesn't recognize deleted files and has problems handling 0 inode. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
* kernel: add support for enabling fit firmware partition parser via cmdlineFelix Fietkau2021-02-281-0/+6

* kernel: add parser finding rootfs after CFE bootfsRafał Miłecki2021-01-223-0/+99
| | | | | | | | | | | | | | It's required for BCM4908. It cannot use "bcm-wfi-fw" parser because that one requires *two* JFFS2 partitions which is untested / unsupported on the BCM4908 architecture. With a single JFFS2 partition "bcm-wfi-fw" parser will: 1. Fail to find "vmlinux.lz" as it doesn't follow "1-openwrt" file 2.

* kernel: mtdsplit: support ELF loader splittingSander Vanheule2020-09-093-0/+293
| | | | | | | | | | | | | | | | | | | | | | | | | To parse the ELF kernel loader, a small ELF parser is used that can handle both ELF32 or ELF64 class loaders. The splitter assumes that the kernel is always located before the rootfs, whether it is embedded in the loader or not. If the kernel is located after the rootfs on the firmware partition, then the rootfs splitter will include it in the dynamically created rootfs_data partition and the kernel will be corrupted. The kernel image is preferably embedded inside the ELF loader, so the end of the loader equals the end of the kernel partition. This is due to the way mtd_find_rootfs_from searches for the the rootfs: - if the kernel image is embedded in the loader, the appended rootfs may follow the loader immediately, within the same erase block. - if the kernel image is not embedded in the loader, but placed at some offset behind the loader (OKLI-style loader), the rootfs must be aligned to an erase-block after the loader and kernel image. In case section header table is empty, determine the elf loader size by finding the end of the last segment, as defined by the program header table.

* generic: routerbootpart MTD parser for RouterBootThibaut VARÈNE2020-05-081-0/+365
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver provides an OF MTD parser to properly assign the RouterBoot partitions on the flash. This parser builds from the "fixed-partitions" one (see ofpart.c), but it can handle dynamic partitions as found on routerboot devices. The parent node must contain the following: compatible = "mikrotik,routerboot-partitions"; #address-cells = <1>; #size-cells = <1>; Children routerbootpart DTS nodes are defined as follows: For fixed partitions node-name@unit-address { reg = <prop-encoded-array>; label = <string>; read-only; lock; }; All properties but reg are optional. For dynamic partitions: node-name { size = <prop-encoded-array>; label = <string>; read-only; lock; }; size property is mandatory unless the next partition is a fixed one or a "well-known" one (matched from the strings defined below) in which case it can be omitted or set to 0; other properties are optional. By default dynamic partitions are appended after the preceding one, except for "well-known" ones which are automatically located on flash. Well-known partitions (matched via label or node-name): - "hard_config" - "soft_config" - "dtb_config" This parser requires the DTS to list partitions in ascending order as expected on the MTD device. This parser has been successfully tested on BE (ath79) and LE (ipq40xx and ramips) hardware.

* kernel: fix include of myloader.o since kernel 5.4Adrian Schmutzler2020-04-241-182/+0
| | | | | | | | | | | | | | | | | | | | | | Between 4.19 and 5.4, mtd parsers have been moved to "parsers" subdirectory. Based on this, the selection of myloader.o in OpenWrt was also moved to that subdirectory, while the Kconfig and our local myloader.c file remained in /drivers/mtd. This resulted in linking errors like the following (on ath25@5.4): make[8]: *** No rule to make target 'drivers/mtd/parsers/myloader.o', ... needed by 'drivers/mtd/parsers/built-in.a'. Stop. make[7]: *** [scripts/Makefile.build:500: drivers/mtd/parsers] Error 2 make[6]: *** [scripts/Makefile.build:500: drivers/mtd] Error 2 Since myloader.c is not too big, this patch moves it to the kernel patches, allowing to adjust the path for kernel 5.4 and keeping Makefiles and file paths better in sync.
