[PATCH 0/3] mikrotik: make soft_config partition writable

[Stefan Hellermann]

Hi,

I tested the series on a Mikrotik LHG 2.

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00020000 00010000 "RouterBoot"
mtd1: 0000e000 00010000 "bootloader1"
mtd2: 00001000 00010000 "hard_config"
mtd3: 00001000 00010000 "bios"
mtd4: 0000f000 00010000 "bootloader2"
mtd5: 00001000 00001000 "soft_config"
mtd6: 00fe0000 00010000 "firmware"
mtd7: 00290000 00010000 "kernel"
mtd8: 00d50000 00010000 "rootfs"
mtd9: 009e0000 00010000 "rootfs_data"

=> erasesize of soft_config is smaller

# cat /sys/firmware/mikrotik/soft_config/boot_proto
[bootp] dhcp
# echo dhcp > /sys/firmware/mikrotik/soft_config/boot_proto
# cat /sys/firmware/mikrotik/soft_config/commit
dirty
# echo 1 > /sys/firmware/mikrotik/soft_config/commit
# cat /sys/firmware/mikrotik/soft_config/boot_proto
bootp [dhcp]
# cat /sys/firmware/mikrotik/soft_config/commit
clean

=> No error, change is written to flash

sysupgrade is also ok, configuration ist saved.
