+Description: A boot loader for layerscape systems
+ Das U-Boot is a cross-platform bootloader for embedded systems,
+ used as the default boot loader by several board vendors.  It is
+ intended to be easy to port and to debug, and runs on many
+ supported architectures, including PPC, ARM, MIPS, x86, m68k,
+ NIOS, and Microblaze.
+ .
+ This package includes boot loaders for various layerscape platforms.

+Subject: ls1028ardb: Set fdtfile so that correct DTB is used
+
+The environment variable `fdtfile` is currently not being set in the
+environment. As a result, a device tree name is being constructed from
+the `soc` and `board` environment variables, which doesn't match the
+naming used for the actual device trees provided by the kernel. Use
+`CONFIG_DEFAULT_FDT_FILE` to provide the required device tree name.
