# Script to burn entire 32MB of BMC SPI Flash 1

# Usage:
# a) Local: /run/initramfs/recovery <bmc-image-file>
#
# 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
#
