mtd_partition(mtd, firstblock, nblocks) takes the partition offset and size in units of the underlying device "blocks" (geo.blocksize), not erase blocks. Several board drivers accumulated partoffset and computed the partition size in erase-block units and passed them straight to mtd_partition(), so on devices where blocksize != erasesize (W25/SST25: 256B vs 4KB, SAMD5E5 progmem: 512B vs 8KB) every partition came out erasesize/blocksize (16x) too small and misaligned. Convert partoffset and partszbytes to geo.blocksize units at the mtd_partition() call site while keeping the erase-block accumulation. Affected boards: - stm32f103-minimum (W25) - at32f437-mini (W25) - stm32f429i-disco (SST25F064, enabled in the extflash defconfig) - metro-m4 (SAMD5E5 progmem) Also fix pre-existing nxstyle violations in the touched files so the change passes checkpatch (see CONTRIBUTING.md).
