2021-05-10mtd: parsers: ofpart: fix parsing subpartitionsRafał Miłecki
ofpart was recently patched to not scan random partition nodes as subpartitions. That change unfortunately broke scanning valid subpartitions like: partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; partition@0 { compatible = "fixed-partitions"; label = "bootloader"; reg = <0x0 0x100000>; partition@0 { label = "config"; reg = <0x80000 0x80000>; }; }; }; Fix that regression by adding 1 more code path. We actually need 3 conditional blocks to support 3 possible cases. This change also makes code easier to understand & follow.

2021-03-11mtd: parsers: ofpart: limit parsing of deprecated DT syntaxRafał Miłecki
For backward compatibility ofpart still supports the old syntax like: spi-flash@0 { compatible = "jedec,spi-nor"; reg = <0x0>; partition@0 { label = "bootloader"; reg = <0x0 0x100000>; }; }; (without "partitions" subnode). There is no reason however to support nested partitions without a clear "compatible" string like: partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; partition@0 { label = "bootloader"; reg = <0x0 0x100000>; partition@0 { label = "config"; reg = <0x80000 0x80000>; }; }; }; (we never officially supported or documented that).

2021-03-11mtd: parsers: ofpart: support BCM4908 fixed partitionsRafał Miłecki
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.

2020-12-07mtd: parser: cmdline: Fix parsing of part-names with colonsSven Eckelmann
Some devices (especially QCA ones) are already using hardcoded partition names with colons in it. The OpenMesh A62 for example provides following mtd relevant information via cmdline: root=31:11 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(custom),64k(0:KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) rootfsname=rootfs rootwait The change to split only on the last colon between mtd-id and partitions will cause newpart to see following string for the first partition: KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) Such a partition list cannot be parsed and thus the device fails to boot. Avoid this behavior by making sure that the start of the first part-name ("(") will also be the last byte the mtd-id split algorithm is using for its colon search.

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space.

Looks like some drivers define MTD names with a colon in it, thus making mtdpart= parsing impossible. Let's fix the parser to gracefully handle that case: the last ':' in a partition definition sequence is considered instead of the first one.

2019-05-06mtd: afs: add v2 partition parsingLinus Walleij
The AFS v2 partition type appear in later ARM reference designs such as RealView, Versatile Express and the 64bit Juno Development Platform. The image informations is padded with a 32bit word (4 bytes) on the 32bit platforms and a 64bit word (8 bytes) on the 64bit platforms. The boot monitor source code gives at hand that this is because the first entry in the struct mapped over the image information is a "next" pointer for a linked list, filled in by firmware after reading in the info block, and always zero in the flash. We adjust padding by checking what padding gives the right checksum. This was tested on: - Integrator/AP (v1 partitions) - RealView PB11MPCore (v2 32bit partitions) - Juno Development System (v2 64bit partitions) All systems display the images in flash very nicely as separate partitions, e.g on Juno: 4 afs partitions found on MTD device 8000000.flash Creating 4 MTD partitions on "8000000.flash": 0x000000040000-0x0000000c0000 : "fip" 0x000000ec0000-0x0000018c0000 : "Image" 0x000000f00000-0x000000f40000 : "juno" 0x000003ec0000-0x000003f00000 : "bl1" Cc: Ryan Harkin <ryan.harkin@linaro.org> Acked-by: Liviu Dudau <liviu.dudau@arm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Richard Weinberger <richard@nod.at>

2019-05-06mtd: afs: simplify partition parsingLinus Walleij
This simplifies the AFS partition parsing to make the code more straight-forward and readable. Before this patch the code tried to calculate the memory required to hold the partition info by adding up the sizes of the strings of the names and adding that to a single memory allocation, indexing the name pointers in front of the struct mtd_partition allocations so all allocated data was in one chunk. This is overzealous. Instead use kstrdup and bail out, kfree():ing the memory used for MTD partitions and names alike on the errorpath. In the process rename the index variable from idx to i.
