| * ARM: Layerscape: Add QSPI boot supportSascha Hauer2019-05-101-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Booting Layerscape from QSPI is a bit tricky and the approach we take is different from the one U-Boot has taken, so it's worth writing and reading the following explanation. The QSPI controller can map the Flash contents into the memory space (On LS1046a at 0x40000000). The PBL unit uses this to read the RCW from this memory window. The Layerscape SoCs have a PowerPC history, so it seemed appropriate for the designers to let the QSPI controller operate in big endian mode by default. To let the SoC see the correct RCW we have to write the RCW and PBI data with be64 endianess. Our PBL image tool pokes the initial binary into the SoC internal SRAM using PBI data as done with SD/MMC boot aswell. barebox then changes the QSPI controller endianess to le64 to properly read the barebox binary (placed at an flash offset of 128KiB, so found in memory at 0x40020000) into SDRAM and jumps to it. U-Boot has another approach. Here the initial binary is executed in place directly at 0x40100000. This means the QSPI controller endianess must be swapped inside the PBI data. This has the effect that the whole RCW/PBI data must be 64bit endianess swapped *except* the very last word of the PBI data which contains the CRC command and is read already with changed endianess. As a conclusion when porting QSPI PBI files from U-Boot to barebox skip commands changing the endianess in the QSPI controller and make sure the image is executed in internal SRAM and not in the Flash memory window. Lines like this should be removed: 09550000 000f400c This sets the binary execution address: 09570604 40100000 For barebox it should be changed to 0x10000000. As a result the PBI files can probably be unified between SD and QSPI boot. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: Layerscape: pblimage: Drop pbl end commandSascha Hauer2019-05-101-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The PBL image tool includes two commands into the image. These are executed after the initial image has been uploaded but before the final CRC check. These commands are "flush" and "wait". According to the reference manual a "flush" command can be used to read back the the value just written to CCSR register space in order to let the previous write complete. This seems unnecessary as the last write was never to the CCSR register space. The "wait" command also seems unnecessary as the time parameter is 0. As all this end_cmd stuff goes back to the PowerPC times and everything still seems to work on Arm let's just remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | scripts: Add Layerscape image toolSascha Hauer2019-03-132-0/+433
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the Layerscape image tool based on the corresponding U-Boot tool. PBL in the name is for "Pre-Boot Loader", just like the barebox PBL support, but here the name is for the Layerscape image format which has the same name. Layerscape SoCs load the initial image portion into SRAM, so only a fraction of the barebox image can initially be loaded. This tool expects the full barebox image and the size of the PBL part of this image specified to the -m option. The full barebox image is then placed in the output image at offset 128KiB.

| * | pbl multiimage: Allow to check image sizesSascha Hauer2019-03-133-2/+46
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PBL images are often constrained in size by limitations exposed by the SoCs SRAM size or partition sizes on the boot device. So far we tried to configure these limits in Kconfig, but with PBL multi images and thus different limitations for the different supported images this no longer works. This patch has another approach for it: During build time make variables containing the relevant sizes for each image are created. These are: PBL_CODE_SIZE_$(symbol) PBL_MEMORY_SIZE_$(symbol) PBL_IMAGE_SIZE_$(symbol) PBL_CODE_SIZE_$(symbol) contains the pure code size of the PBL, it should be smaller than the available SRAM during boot. Normally the PBL's bss segment also needs to be in the initial SRAM, for this case PBL_MEMORY_SIZE_$(symbol) is the relevant variable. PBL_IMAGE_SIZE_$(symbol) contains the full size of the PBL image including the compressed payload (but without any image headers created later by SoC specific image tools). $(symbol) is a placeholder for the start symbol used for this PBL image, thus for the i.MX53 QSB with entry start_imx53_loco PBL_CODE_SIZE_start_imx53_loco will be created. The images/Makefile.* can use these variables directly to check sizes or specify the same variables with a "MAX_" prefix. So when images/Makefile.imx specifies MAX_PBL_CODE_SIZE_start_imx53_loco = 0x10000 then the build system will make sure that the PBL code for the QSB will not get bigger than 64KiB. Also included in this patch are the size restrictions for the i.MX8MQ images as an example how to use this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | The defaultenv should be rebuilt once a file in it has changed. the genenv script always generates the environment file to a temporary file. Only if it has changed to the last target file the temporary file is moved over the target file. This means we always have to call genenv, thus replace "if_changed" with "cmd". With this dependencies are correctly tracked. New or changed files result in new image builds whereas unchanged environments do not unnecessarily result in new images.

This provides better maintainability than version-controlling pre-generated C files with a "_shipped" suffix. This commit imports flex and bison rules from Linux, and deletes pre-generated parsers and lexers.

Clean them up globally from the top Makefile. Some of the final host programs those lexer/parser are linked into are necessary for building external modules, but the intermediates are unneeded.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | When an image is loaded to SRAM we can normally only load a part of the full image, limited by the available space in SRAM. We currently load the pblb image which is the executable part of the PBL without the compressed barebox payload. We are going to link the compressed barebox image into the pbl image though, so we can't see the desired load size from outside the image anymore. This adds a max_load_size option to set this size explicitly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
