Hi all:

    I encounter bmc firmware update fail issue and message is "Verify error: update: --no-flash --ignore-mount --no-save-files --no-restore-files --no-clean-saved-files\nERROR: Unable to find mtd partition for image-bmc.\n".

I check my flash partition and found that I lost "bmc" partition as below:

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00060000 00001000 "u-boot"
mtd1: 00020000 00001000 "u-boot-env"
mtd2: 00440000 00001000 "kernel"
mtd3: 01740000 00001000 "rofs"
mtd4: 00400000 00001000 "rwfs"

ls -l /dev/mtd
lrwxrwxrwx    1 root     root             7 May 23 11:56 kernel -> ../mtd2
lrwxrwxrwx    1 root     root             7 May 23 11:56 rofs -> ../mtd3
lrwxrwxrwx    1 root     root             7 May 23 11:56 rwfs -> ../mtd4
lrwxrwxrwx    1 root     root             7 May 23 11:56 u-boot -> ../mtd0

I tried to add bmc partition in dts 

&bootspi {
        status = "okay";
        flash@0 {
                status = "okay";
                m25p,fast-read;
                label = "bmc";
                spi-max-frequency = <50000000>;
#include "openbmc-flash-layout.dtsi"
        };
};

but there still is no "bmc" partition. Could someone give any suggestion? thanks.
