+#
+# Assumptions:
+#    <bmc-image-file> is a 32MB file representing all partitions in BMC SPI Flash
+#    <bmc-image-file> exists on local filesystem
+#    /dev/mtd0 represents entire BMC SPI Flash device
+#    /dev/mtd5 is a JFFS2 filesystem (rwfs) partition
+#    /bsp/reset/bmc_upgrade is symlink pointing to proper sticky bit in CPLD
