 #!/bin/bash
 
+# Tool mainly for U-Boot Quality Assurance: build one or more board
+# configurations with minimal verbosity, showing only warnings and
+# errors.
+#
+# There are several ways to select which boards to build.
+#
+# Traditionally, architecture names (like "powerpc"), CPU family names
+# (like "mpc83xx") or board names can be specified on the command
+# line; without any arguments, MAKEALL defaults to building all Power
+# Architecture systems (i. e. same as for "MAKEALL powerpc").
+#
+# With the iontroduction of the board.cfg file, it has become possible
+# to provide additional selections.  We use standard command line
+# options for this:
+#
+# -a or --arch	:	Select architecture
+# -c or --cpu	:	Select CPU family
+# -s or --soc	:	Select SoC type
+# -v or --vendor:	Select board vendor
+#
+# Selections by these options are logically ANDed; if the same option
+# is used repeatedly, such selections are ORed.  So "-v FOO -v BAR"
+# will select all configurations where the vendor is either FOO or
+# BAR.  Any additional arguments specified on the command line are
+# always build additionally.
+#
+# Examples:
+#
+# - build all Power Architecture boards:
+#
+#	MAKEALL -a powerpc
+#   or
+#	MAKEALL --arch powerpc
+#   or
+#	MAKEALL powerpc
+#
+# - build all PowerPC boards manufactured by vendor "esd":
+#
+#	MAKEALL -a powerpc -v esd
+#
+# - build all PowerPC boards manufactured either by "keymile" or
+#   "siemens":
+#
+#	MAKEALL -a powerpc -v keymile -v siemens
+#
+# - build all Freescale boards with MPC83xx CPUs, plus all 4xx boards:
+#
+#	MAKEALL -c mpc83xx -v freescale 4xx
