# 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 introduction 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
