2023-03-08mtd: bcm63xxpart: remove MODULE_LICENSE in non-modulesNick Alcock1-1/+0
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2023-02-06mtd: parsers: ofpart: add workaround for #size-cells 0Francesco Dolcini1-0/+19
Add a mechanism to handle the case in which partitions are present as direct child of the nand controller node and #size-cells is set to <0>. This could happen if the nand-controller node in the DTS is supposed to have #size-cells set to 0, but for some historical reason/bug it was set to 1 in the past, and the firmware (e.g. U-Boot) is adding the partition as direct children of the nand-controller defaulting to #size-cells being to 1. This prevents a real boot failure on colibri-imx7 that happened during v6.1 development cycles.

2022-11-18mtd: parsers: refer to ARCH_BCMBCA instead of ARCH_BCM4908Lukas Bulwahn1-1/+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.

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.

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.
