[RFC PATCH] mtd: spi-nor: write support for minor aligned partitions

access to 4K erase without requiring CONFIG_MTD_SPI_NOR_USE_4K_SECTORS Introduce mtd struct erasesize_minor, the smallest erasesize supported by the device. Do not prevent writing to mtd partitions where a partition boundary sits on a minor erasesize boundary. Signed-off-by: John Thomson --- Have

Re: [PATCH] MIPS: zboot: put appended dtb into a section

work boot tested this change on ath79 hardware: - kernel vmlinuz.bin then appended DTB, and packed into a uImage (out of kernel tree) - kernel vmlinuz then updated ELF DTB appended_dtb section, and ELF booted Cheers, -- John Thomson

Re: [PATCH 2/2] mips: boot compressed: add support for vlinuz ELF DTB

I think it would be safer to make these changes by adding a different boot/compressed target: vmlinuz.elf? So that this would not break kernel build cases where both a normal RAW_APPENDED_DTB zImage is wanted, and additionally an ELF boot vmlinuz.elf. -- John Thomson
