Some commits were applied on top of that since then, but equivalent fixups were done in Linux. So, this commit overwrites everything scripts/kconfig/ with the one from Linux 4.20 Highlights: - 'silentoldconfig' has been renamed to 'syncconfig' (the top Makefile needs to be adjusted) - 'testconfig' target has been added for unit-tests (the top Makefile needs to export PYTHON3 because the test frame relies on Python3 and pytest) - The perfect hash table generated by gperf has been removed - The localization support has been removed - The 'option env=VAR' has been replaced with more generic variable reference syntax $(VAR) (./Kconfig and common/Kconfig need to be adjusted) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Files generated by if_changed* must be added to 'targets' to include *.cmd files. Otherwise, they would be regenerated every time. The build system automatically adds objects to 'targets' where appropriate, such as obj-y, extra-y, etc. but does nothing for intermediate files. So, each Makefile needs to add them by itself. There are some common cases where objects are generated by chained rules. Lexers and parsers are compiled like follows: %.lex.o <- %.lex.c <- %.l %.tab.o <- %.tab.c <- %.y They are common patterns, so it is reasonable to take care of them in the core Makefile instead of requiring each Makefile to do so.

| * | kbuild: add .SECONDARY special targetMasahiro Yamada2019-01-031-0/+3

GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped arch/arm/crypto/Makefile marks such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. .SECONDARY with no prerequisites causes all targets to be treated as secondary. This agrees the policy of Kbuild. scripts/Kbuild.include seems a suitable place to add it because it is included from almost all sub-makes. I deleted 'SECONDARY' (no dot) from images/Makefile, which I guess a typo. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This is needed to make sure that it is remade from scratch when Make is next run; if Make is interrupted after the recipe has begun to write the target file, it results in an incomplete file whose time stamp is newer than that of the prerequisites files. Make automatically deletes the incomplete file on interrupt unless the target is marked .PRECIOUS. The situation is just the same as when the shell fails for some reasons. Usually when a recipe line fails, if it has changed the target file at all, the file is corrupted, or at least it is not completely updated. Yet the file’s time stamp says that it is now up to date, so the next time Make runs, it will not try to update that file. However, Make does not cater to delete the incomplete target file in this case. We need to add .DELETE_ON_ERROR somewhere in the Makefile to request it. scripts/Kbuild.include seems a suitable place to add it because it is included from almost all sub-makes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .imxcfg configuration files support few more commands, all starting with "hab_encrypt" string. That way it is possible to easily ignore these commands, when image encryption was not requested. Hence, we can use single .imxcfg file to generate signed and encrypted images in the same build. Images are encrypted in place by Freescale Code Signing Tool (cst), using Data Encryption Key (DEK). This key needs to be encapsulated by processor's hardware encryption engine to produce DEK blob, which is unique for each device. DEK blob needs to be part of CSF area, so we make enough space on the end of image to simply append it later, e.g. during device flash procedure. Introduced code was developed and tested on NXP i.MX6UL platform. Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hab_blocks command is used to specify image authentication blocks for HAB. Currently it was configured to authenticate full barebox image. However in case of booting from SD card and adding MBR partition table, HAB authentication fails, as final boot image is modified. Add an optional argument to hab_blocks command, to select between 3 types of authentication areas: - full: whole barebox image will be authenticated (this is default to keep compatibility), - from-dcdofs: image area up to dcdofs is not authenticated, so any changes up to dcdofs are possible, - skip-mbr: image area from 440 to 512 bytes is excluded from beeing authenticated, which allows to add / modify MBR partition table after building barebox image.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Older versions of "cst" want to read the CSF from STDIN, while newer versions want to read the CSF from a file. Sadly, the "-i" option doesn't understand "-i -" to read from STDIN, so we give it "/dev/stdin" instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building HAB images for i.MX we have to specify some pathes to the certificates. This can be done with Kconfig variables. For better build system integration we also want to be able to specify the pathes in environment variables. This currently doesn't work as we specify the variables from the environment with the -D option to cpp, but also include generated/autoconf.h which overwrites the variables with the values from Kconfig. To overcome this introduce a Kconfig switch that explcitly selects whether we want to have the variables from Kconfig or the environment. Also, only pass the variables from the environment when explicitly wanted. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some vendors fuse their devices so that the IMX USB ROM loader identifies itself with a different Vendor and Product ID on USB enumeration. Currently, imx-usb-loader will refuse to detect and work with such devices, so let's teach it. Because we cannot easily detect the device type from the USB ID in this case, introduce the new command line parameter -d <type> to specify the device type to use on the device path specified with -p <path>, even if the VID/PID pair of that device is unknown. The device name is sourced from the "name" field of the imx_ids array of known devices at the top of the file. Using "-d list" will print a list of known device types. Using -d without -p will not do anything useful, except generate a warning. Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | find_imx_dev() loops through all USB devices, tries to open them, and then compares the chosen device path (given with -p on the command line) to the path of the currently opened device. The device path can be checked earlier, opening the device is not neccessary. We fail early here because in the next commit we want to enable the user to force using a device by specifying its path. Opening every single device available on the system then leads to unnecessary error messages for all devices that do not match the provided path.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | Boot header on i.MX8MQ SoC allows embedding signed HDMI firmware images that are used by mask ROM code during the very early stages of boot. Since providing that firmware appear to be necessary to enable SoC's HDMI/DP functionality extend imx-image tool to support this feature. To do that add code implementing "signed_hdmi_firmware" keyword, which allows users to specify a path to a binary blob containing all of the necessary headers and footers as well firmware data and code sections (this is how such images are provieded by NXP) Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
