      Makefile: prepare for using Kbuild-style Makefile · ce28d7ac
      由 Masahiro Yamada 提交于 
      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.

      TPL : introduce the TPL based on the SPL · 3aa29de0
      由 Ying Zhang 提交于 
      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

      SPL: Makefile: Build a separate autoconf.mk for SPL · 39bc12dd
      由 Joel Fernandes 提交于 
      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.

      Licenses: introduce SPDX Unique Lincense Identifiers · eca3aeb3
      由 Wolfgang Denk 提交于 
      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:

| It is not a conflict to grant a license and also reserve all rights, as
| implicit in that language is that you are reserving all "other" rights
| not granted in the license.  Thus, a file with "Licensed under GPL, All
| Rights Reserved" would mean that it is licensed under the GPL, but no
| other rights are given to copy, modify or redistribute it.

      image: Add RSA support for image signing · 19c402af
      由 Simon Glass 提交于 
      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.

      arm: mxs: Preprocess u-boot.bd so they contain full path · 714dc001
      由 Marek Vasut 提交于 
      The u-boot-imx23.bd and u-boot-imx28.bd need to be preprocessed, otherwise
they have issues with out-of-tree build where elftosb tool couldn't sometimes
find the u-boot.bin and spl/u-boot-spl.bin .

Preprocess these .bd files with sed and insert full path to u-boot.bin and
spl/u-boot-spl.bin to prevent this issue. Moreover, to avoid adding more
churn into main Makefile, move all this preprocessing and u-boot.sb generation
into CPU directory instead.

      Trigger generic board error only when building · fada9e20
      由 Simon Glass 提交于 
      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.

for i.MX6 will also use these functions. So lets move them to a
