mtd: parsers: bcm47xxpart: Fix halfblock reads

2022-10-18T09:20:12Z

There is some code in the parser that tries to read 0x8000 bytes into a block to "read in the middle" of the block. Well that only works if the block is also 0x10000 bytes all the time, else we get these parse errors as we reach the end of the flash: spi-nor spi0.0: mx25l1606e (2048 Kbytes) mtd_read error while parsing (offset: 0x200000): -22 mtd_read error while parsing (offset: 0x201000): -22 (...) Fix the code to do what I think was intended.

mtd: move from strlcpy with unused retval to strscpy

2022-09-19T16:14:53Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

arm64: bcmbca: Make BCM4908 drivers depend on ARCH_BCMBCA

2022-08-15T16:55:34Z

With Broadcom Broadband arch ARCH_BCMBCA supported in the kernel, this patch series migrate the ARCH_BCM4908 symbol to ARCH_BCMBCA. Hence replace ARCH_BCM4908 with ARCH_BCMBCA in subsystem Kconfig files.

of_get_child_by_name() will increase the refcount of 'ofpart_node', so add of_node_put() after using it to avoid refcount leak.

mtd: parsers: add support for Sercomm partitions

2022-06-09T13:03:32Z

This adds an MTD partition parser for the Sercomm partition table that is used in some Beeline, Netgear and Sercomm routers. The Sercomm partition map table contains real partition offsets, which may differ from device to device depending on the number and location of bad blocks on NAND.
