-# All Struct objects are initialized by a special string with the following

-"""A utility to generate ipq8064 uber SBL..
-
-The very first blob (aka 'uber SBL') read out of NOR SPI flash by the IPQ8064
-maskrom is supposed to be a concatenation of up to three binaries: one to run
-on the RPM, another one to run on the AP, and the third one - the actual
-coreboot bootblock.
-
-The uber SBL starts with the combined header descriptor of 80 bytes, with the
-first two 4 byte words set to certain values, and the total size of the
-payload saved at offsets 28 and 32.
-
-To generate the uber SBL this utility expects two or three input file names in
-the command line, the first file including the described header, and the
-following one(s) - in QCA MBN format. This allows to create the uber SBL in
-one or two invocations.
-
-The input files are concatenated together aligned at 256 byte boundary offset
-from the combined header. See Usage() below for more details.
-
-The resulting uber SBL file is prepended by the same combined header adjusted
-to reflect the new total file size.
