kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

# We are using a recursive build, so we need to do a little thinking
|
|
|
|
# to get the ordering right.
|
|
|
|
#
|
|
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
|
|
# their own directory. If in some directory we have a dependency on
|
|
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
|
|
# after that we are sure that everything which is in that other dir
|
|
|
|
# is now up to date.
|
|
|
|
#
|
|
|
|
# The only cases where we need to modify files which have global
|
|
|
|
# effects are thus separated out and done before the recursive
|
|
|
|
# descending is started. They are now explicitly listed as the
|
|
|
|
# prepare rule.

# $(quiet) to choose other forms of output instead, e.g.
|

|
|
# quiet_cmd_cc_o_c = Compiling $(RELDIR)/$@
|
|
|
|
# cmd_cc_o_c = $(CC) $(c_flags) -c -o $@ $<
|
|
|
|
#
|
|
|
|
# If $(quiet) is empty, the whole command will be printed.
|
|
|
|
# If it is set to "quiet_", only the short version will be printed.
|
|
|
|
# If it is set to "silent_", nothing will be printed at all, since
|
|
|
|
# the variable $(silent_cmd_cc_o_c) doesn't exist.
|
|
|
|
#
|
|

# A simple variant is to prefix commands with $(Q) - that's useful

kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:

This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.

(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

arm: mxs: Add support for generating signed BootStream
This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.
To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.
