Do you have the flash-kernel package installed? That is the job it
serves.
The database contains this:
Machine: Freescale i.MX53 Quick Start Board
Machine: Freescale MX53 LOCO Board
Kernel-Flavors: armmp mx5
DTB-Id: imx53-qsb.dtb
DTB-Append-From: 3.12
Boot-DTB-Path: /boot/dtb
U-Boot-Kernel-Address: 0x70008000
U-Boot-Initrd-Address: 0x0
Boot-Kernel-Path: /boot/uImage
Boot-Initrd-Path: /boot/uInitrd
Required-Packages: u-boot-tools
Bootloader-Sets-Incorrect-Root: no
So looks like that should work if installed.
