* mtd: parsers: ofpart: support BCM4908 fixed partitionsRafał Miłecki2021-03-111-0/+9
| | | | | | | | | | | | | | | | | | Some devices use fixed partitioning with some partitions requiring some extra logic. E.g. BCM4908 may have multiple firmware partitions but detecting currently used one requires checking bootloader parameters. To support such cases without duplicating a lot of code (without copying most of the ofpart.c code) support for post-parsing callback was added. BCM4908 support in ofpart can be enabled using config option and results in compiling & executing a specific callback. It simply reads offset of currently used firmware partition from the DT. Bootloader specifies it using the "brcm_blparms" property.

* mtd: parsers: bcm63xx: Do not make it modularFlorian Fainelli2020-10-021-1/+1
| | | | | | | | | | | | | | | | With commit 91e81150d388 ("mtd: parsers: bcm63xx: simplify CFE detection"), we generate a reference to fw_arg3 which is the fourth firmware/command line argument on MIPS platforms. That symbol is not exported and would cause a linking failure. The parser is typically necessary to boot a BCM63xx-based system anyway so having it be part of the kernel image makes sense, therefore make it 'bool' instead of 'tristate'.

* mtd: sharpslpart: Add sharpslpart partition parserAndrea Adami2017-11-131-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Sharp SL Series (Zaurus) PXA handhelds have 16/64/128M of NAND flash and share the same layout of the first 7M partition, managed by Sharp FTL. GPL 2.4 sources: http://support.ezaurus.com/developer/source/source_dl.asp The purpose of this self-contained patch is to add a common parser and remove the hardcoded sizes in the board files (these devices are not yet converted to devicetree). Users will have benefits because the mtdparts= tag will not be necessary anymore and they will be free to repartition the little sized flash. The obsolete bootloader can not pass the partitioning info to modern kernels anymore so it has to be read from flash at known logical addresses. (see http://www.h5.dion.ne.jp/~rimemoon/zaurus/memo_006.htm ) In kernel, under arch/arm/mach-pxa we have already 8 machines: MACH_POODLE, MACH_CORGI, MACH_SHEPERD, MACH_HUSKY, MACH_AKITA, MACH_SPITZ, MACH_BORZOI, MACH_TOSA. Lost after the 2.4 vendor kernel are MACH_BOXER and MACH_TERRIER. Almost every model has different factory partitioning: add to this the units can be repartitioned by users with userspace tools (nandlogical) and installers for popular (back then) linux distributions. The Parameter Area in the first (boot) partition extends from 0x00040000 to 0x0007bfff (176k) and contains two copies of the partition table: ... 0x00060000: Partition Info1 16k 0x00064000: Partition Info2 16k 0x00668000: Model 16k ... The first 7M partition is managed by the Sharp FTL reserving 5% + 1 blocks for wear-leveling: some blocks are remapped and one layer of translation (logical to physical) is necessary. There isn't much documentation about this FTL in the 2.4 sources, just the MTD methods for reading and writing using logical addresses and the block management (wear-leveling, use counter). It seems this FTL was tailored with 16KiB eraesize in mind so to fit one param block exactly, to have two copies of the partition table on two blocks. Later pxa27x devices have same size but 128KiB erasesize and less blocks (56 vs. 448) but the same schema was adopted, even if the two tables are now in the same eraseblock. For the purpose of the MTD parser only the read part of the code was taken. The NAND drivers that can use this parser are sharpsl.c and tmio_nand.c.

* mtd: extract TRX parser out of bcm47xxpart into a separated moduleRafał Miłecki2017-06-221-0/+8
This makes TRX parsing code reusable with other platforms and parsers. Please note this patch doesn't really change anything in the existing code, just moves it. There is still some place for improvement (e.g. working on non-hacky method of checking rootfs format) but it's not really a subject of this change.
