#!/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 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

Usage: MAKEALL [options] [--] [boards-to-build]
|

|

Options:
|

-a ARCH, --arch ARCH Build all boards with arch ARCH
|
||||
-c CPU, --cpu CPU Build all boards with cpu CPU
|

-v VENDOR, --vendor VENDOR Build all boards with vendor 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. See the boards.cfg file for more info.
|
||||
|
||||
If no boards are specified, then the default is "powerpc".
|
||||
|
||||
Environment variables:
|
||||
BUILD_NCPUS number of parallel make jobs (default: auto)
|
||||
CROSS_COMPILE cross-compiler toolchain prefix (default: "")
|
||||
MAKEALL_LOGDIR output all logs to here (default: ./LOG/)
|
||||
BUILD_DIR output build directory (default: ./)

Examples:

- build all Power Architecture boards:

MAKEALL --arch powerpc

MAKEALL powerpc
