* mtd: parsers: refer to ARCH_BCMBCA instead of ARCH_BCM4908Lukas Bulwahn2022-11-171-1/+1
| | | | | | | | | | | | | | | | | | | Commit dd5c672d7ca9 ("arm64: bcmbca: Merge ARCH_BCM4908 to ARCH_BCMBCA") removes config ARCH_BCM4908 as config ARCH_BCMBCA has the same intent. Probably due to concurrent development, commit 002181f5b150 ("mtd: parsers: add Broadcom's U-Boot parser") introduces 'Broadcom's U-Boot partition parser' that depends on ARCH_BCM4908, but this use was not visible during the config refactoring from the commit above. Hence, these two changes create a reference to a non-existing config symbol. Adjust the MTD_BRCM_U_BOOT definition to refer to ARCH_BCMBCA instead of ARCH_BCM4908 to remove the reference to the non-existing config symbol ARCH_BCM4908.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
