2013-11-01Makefile: convert makefiles to Kbuild style and delete grep switchMasahiro Yamada
We have converted all makefiles needed to build $(LIBS). Until this commit we used to grep switch so that U-Boot style and Kbuild style makefiles coexist. But we do not need any more. Goint forward, use always Kbuild style Makefile when adding a new Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2013-10-31Makefile: prepare for using Kbuild-style MakefileMasahiro Yamada
Every makefile in sub directories has common lines at the top and the bottom. This commit pushes the common parts into script/Makefile.build. Going forward sub-makefiles only need to describe this part: COBJS := ... COBJS += ... SOBJS := ... But using obj-y is preferable to prepare for switching to Kbuild. The conventional (non-Kbuild) Makefile style is still supported. This is achieved by greping the Makefile before entering into it. U-Boot conventional sub makefiles always include some other makefiles. So the build system searches a line beginning with "include" keyword in the makefile in order to distinguish which style it is. If the Makefile include a "include" line, we assume it is a conventional U-Boot style. Otherwise, it is treated as a Kbuild-style makefile. With this tweak, we can switch sub-makefiles from U-Boot style to Kbuild style little by little. obj-y := foo/ syntax (descending into the sub directory) is not supportd yet. It will be implemented in the upcomming commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Simon Glass <sjg@chromium.org> Cc: Tom Rini <trini@ti.com>

2013-09-20Makefile: Do not show make debug messagesMasahiro Yamada
In commit 27af930, the top Makefile was adjusted to the new boards.cfg format. But at the same time, -d option was added. If you configure and make separately, for example like follows: make omap4_panda_config make CROSS_COMPILE=<your_compiler_prefix> it works fine as it did before. But if you do them in one time like follows: make omap4_panda CROSS_COMPILE=<your_compiler_prefix> The log is sprinkled with annoying make debug messages. This commit deletes -d option again.

2013-08-20TPL : introduce the TPL based on the SPLYing Zhang
Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can not be more than 4K. So, the SPL cannot initialize the DDR with the SPD code. This patch introduces TPL to enable a loader stub that is loaded by the code from the SPL. It initializes the DDR with the SPD or other operations. The TPL's size is sizeable, the maximum size is decided by the memory's size that TPL runs. It initializes the DDR through SPD code, and copys final uboot image to DDR. So there are three stage uboot images: * spl_boot, * tpl_boot, * final uboot image Signed-off-by: Ying Zhang <b40530@freescale.com> Acked-by: York Sun <yorksun@freescale.com>
2013-08-19SPL: Makefile: Build a separate autoconf.mk for SPLJoel Fernandes
SPL defines CONFIG_SPL_BUILD but this does not percolate to the autoconf.mk Makefile. As a result the build breaks when CONFIG_SPL_BUILD is used in the board-specific include header file. With this, there is a possibility of having a CONFIG option defined in the header file but not defined in the Makefile causing all kinds of build failure and problems. It also messes things for up, for example, when one might want to undefine options to keep the SPL small and doesn't want to be stuck with the CONFIG options used for U-boot. Lastly, this also avoids defining special CONFIG_SPL_ variables for cases where some options are required in U-boot but not in SPL. We add a spl-autoconf.mk rule that is generated for SPL with the CONFIG_SPL_BUILD flag and conditionally include it for SPL builds.

2013-07-24Licenses: introduce SPDX Unique Lincense IdentifiersWolfgang Denk
Like many other projects, U-Boot has a tradition of including big blocks of License headers in all files. This not only blows up the source code with mostly redundant information, but also makes it very difficult to generate License Clearing Reports. An additional problem is that even the same lincenses are referred to by a number of slightly varying text blocks (full, abbreviated, different indentation, line wrapping and/or white space, with obsolete address information, ...) which makes automatic processing a nightmare. To make this easier, such license headers in the source files will be replaced with a single line reference to Unique Lincense Identifiers as defined by the Linux Foundation's SPDX project [1]. For example, in a source file the full "GPL v2.0 or later" header text will be replaced by a single line: SPDX-License-Identifier: GPL-2.0+ We use the SPDX Unique Lincense Identifiers here; these are available at [2]. Note: From the legal point of view, this patch is supposed to be only a change to the textual representation of the license information, but in no way any change to the actual license terms. With this patch applied, all files will still be licensed under the same terms they were before. Note 2: The apparent difference between the old "COPYING" and the new "Licenses/gpl-2.0.txt" only results from switching to the upstream version of the license which is differently formatted; there are not any actual changes to the content. Note 3: There are some recurring questions about linense issues, such as: - Is a "All Rights Reserved" clause a problem in GPL code? - Are files without any license header a problem? - Do we need license headers at all? The following excerpt from an e-mail by Daniel B. Ravicher should help with these: | Message-ID: <4ADF8CAA.5030808@softwarefreedom.org> | Date: Wed, 21 Oct 2009 18:35:22 -0400 | From: "Daniel B.

2013-06-26image: Add RSA support for image signingSimon Glass
RSA provides a public key encryption facility which is ideal for image signing and verification. Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage). To avoid bringing large libraries into the U-Boot binary, the RSA public key is encoded using a simple numeric representation in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-05-01Trigger generic board error only when buildingSimon Glass
At present the generic board error can occur when configuring U-Boot, or during distclean, but this is incorrect. The existing autoconf.mk may come from an earlier U-Boot configuration which is about to be overwritten. Make the error conditional so that it will only be triggered when we are actually building U-Boot. This avoids a problem where the system is being reconfigured to remove CONFIG_SYS_GENERIC_BOARD on an architecture that does not support it. Currently this will print an error and require the manual removal of include/autoconf.mk. Signed-off-by: Simon Glass <sjg@chromium.org>
