On Mikrotik SPI NOR devices, the firmware partition must be erased when flashing from stock firmware, otherwise leftover bits (in particular a kernel signature) can trigger a boot loop. When booted from initramfs (the only way to install OpenWRT on these devices), this patch unconditionally erases the firmware partition in the do_upgrade() stage for all supported SPI NOR devices.
