=========================================================
The purpose of the BSP patch is to allow building
several boards inside the same buildroot tree.
For this to work, each board has to have its
own "$(TARGET_DIR)" and all *configurable* packages
must be rebuilt for each board.
They are now built in the "$(PROJECT_BUILD_DIR)"
All non configurable packages can and should still
be built in the "$(BUILD_DIR)".
If a package is built for one board, then when
you build for a second board of the same architecture
the build becomes a simple copy of the resulting
binaries.
-----
Define BR2_PROJECT which will be used as the selector
between different boards. Note that BR2_PROJECT allow
you to build multiple root file systems for a single
board, and should not be confused with BR2_BOARD_NAME
which relates to the H/W.
-----
Define PROJECT_BUILD_DIR as "PROJECT_BUILD_DIR/$(PROJECT)"
Define BINARIES_DIR as "binaries/$(PROJECT)"
Define TARGET_DIR as "$(PROJECT_BUILD_DIR)/root"
(some prefix/postfix may apply)
Resulting images are stored in "$(BINARIES_DIR)"
-----
Define a few new environment variables in Makefile
PROJECT: Stripped BR2_PROJECT
DATE: Date of build in YYYY-MM-DD format
HOSTNAME: Stripped BR2_HOSTNAME => /etc/hostname
BANNER: Stripped BR2_BANNER => /etc/issue
Linux and Busybox will be built in $(PROJECT_BUILD_DIR)
More patches will be needed later to ensure all
configurable packages are built in this directory.
svn 14777 seems to have broken cramfs/squashfs/tarroot.
The problem is that $(IMAGE) is the absolute path of the image including
directories, so the build tries to access
$(STAGING_DIR)/_fakeroot.</full/path/to/buildroot/directory> which doesn't
exist.
The fix is to define CRAMFS/SQUASHFS/TAR_TARGET as $(notdir
$(IMAGE).<extension>) instead.
0000040: Adds options to jffs2 filesystem creation
Brings jffs2 up to the 20041007 build level so it will compile with both 2.4
and 2.6 kernels.
Adds ability to specify eraseblock and pad sizes, permissions squash,
big/little endian and device table in the configuration.
Also adds capability to copy the resulting image to a secondary location like
a tftp server's root directory.
mtd.patch adds capabilities of the previously attached patch plus allows you to
compile a version of the utilities to run on the target system.
So now there's a set of config options under package to compile the utils for
distribution to the target and a set of config options under target to create a
jffs2 filesystem.
