2019-07-24binman: Add an image headerSimon Glass
It is useful to be able to quickly locate the FDT map in the image. An easy way to do this is with a pointer at the start or end of the image. Add an 'image header' entry, which places a magic number followed by a pointer to the FDT map. This can be located at the start or end of the image, or at a chosen location. As part of this, update GetSiblingImagePos() to detect missing siblings. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Add an FDT mapSimon Glass
An FDT map is an entry which holds a full description of the image entries, in FDT format. It can be discovered using the magic string at its start. Tools can locate and read this entry to find out what entries are in the image and where each entry is located. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-07-24binman: Simplify the entry testSimon Glass
The current test for the 'entry' module is a bit convoluted since it has to import the module multiple times. It also relies on ordering, in that test1EntryNoImportLib() must run before test2EntryImportLib() if they are running in the same Python process. This is unreliable since neither the ordering of tests nor the process that they run in is defined. Fix this by always reloading the entry in these two tests. Also add a check that the expected value of have_importlib is obtained. This corrects a code-coverage problem in the 'entry' module on some systems. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Add support for fixed-offset files in CBFSSimon Glass
A feature of CBFS is that it allows files to be positioned at particular offset (as with binman in general). This is useful to support execute-in-place (XIP) code, since this may not be relocatable. Add a new cbfs-offset property to control this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Pad empty areas of the CBFS with filesSimon Glass
When there is lots of open space in a CBFS it is normally padded with 'empty' files so that sequentially scanning the CBFS can skip from one to the next without a break. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-07-24binman: Add a utility library for coreboot CBFSSimon Glass
Coreboot uses a simple flash-based filesystem called Coreboot Filesystem (CBFS) to organise files used during boot. This allows files to be named and their position in the flash to be set. It has special features for dealing with x86 devices which typically memory-map their SPI flash to the top of 32-bit address space and need a 'boot block' ending there. Create a library to help create and read CBFS files. This includes a writer class, a reader class and associated other helpers. Only a subset of features are currently supported.

2019-07-24binman: Pass the toolpath to testsSimon Glass

2019-07-24distro_bootcmd: refactor virtio to support PCI block devicesDavid Abdurachmanov
Starting libvirt v5.3.0 with QEMU 4.0.0 use of PCI is automatic and thus storage is connected via PCI, which is not visible to U-Boot out-of-the-box. Refactor to do "pci enum" followed by "virtio scan" to see PCI connected storage, and allow bootloader to load kernel and initramfs images.

2019-07-24env: am57xx: Implement A/B boot processRuslan Trofymenko
Add support for A/B boot process on AM57xx based boards: 1. Define 'slot_suffix' variable (using 'ab_select' command) 2. Extend 'emmc_android_boot' boot command (add commands for A/B boot process) 'ab_select' command is used to decide which slot should be used for booting up. A/B metadata resides in 'misc' partition. To activate the A/B boot process, the following config options must be set: CONFIG_ANDROID_AB=y CONFIG_CMD_AB_SELECT=y For successful A/B boot, the corresponding A/B infrastructure must be involved on Android side [1] (including mounting system as root), and disk must be partitioned accordingly. When A/B boot is enabled, there are some known limitations currently exist (not related to A/B patches, need to be implemented later): 1. The 'Verified Boot' sequence is not supported 2. dev path to system partition (system_a or system_b) is passed via 'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but further we'll need to rework it with respect to dm-verity requirements [2] In case when A/B partitions are not present in system (and A/B boot is enabled), boot up process will be terminated and next message will be shown: "boot_a(b) partition not found" [1] https://source.android.com/devices/tech/ota/ab [2] https://source.android.com/devices/tech/ota/ab/ab_implement#kernel Signed-off-by: Ruslan Trofymenko <ruslan.trofymenko@linaro.org> Signed-off-by: Igor Opaniuk <igor.opaniuk@gmail.com> Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Alistair Strachan <astrachan@google.com> Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>

2019-07-24cmd: bcb: Use strcmp() instead of strncmp() for string literalsEugeniu Rosca
Quote from https://patchwork.ozlabs.org/patch/1104244/#2210814: ----------8<----------- strncmp() is chosen for the sake of paranoid/defensive programming. Indeed, strncmp() is not really needed when comparing a variable with a string literal. We expect strcmp() to behave safely even if the string variable is not NUL-terminated. In the same scenario, Linux v5.2-rc7 uses both strcmp() and strncmp(), but the frequency of strcmp() is higher: $ git --version git version 2.22.0 $ (Linux 5.2-rc7) git grep -En 'strncmp\([^"]*"[[:alnum:]]+"' | wc -l 1066 $ (Linux 5.2-rc7) git grep -En 'strcmp\([^"]*"[[:alnum:]]+"' | wc -l 1968 A quick "strcmp vs strncmp" object size test shows that strcmp() generates smaller memory footprint (gcc-8, x86_64): $ (U-Boot) size cmd/bcb-strncmp.o cmd/bcb-strcmp.o text data bss dec hex filename 3373 400 2048 5821 16bd cmd/bcb-strncmp.o 3314 400 2048 5762 1682 cmd/bcb-strcmp.o So, overall, I agree to use strcmp() whenever variables are compared with string literals. ----------8<----------- Fixes: db7b7a05b267 ("cmd: Add 'bcb' command to read/modify/write BCB fields") Reported-by: Simon Glass <sjg@chromium.org> Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Igor Opaniuk <igor.opaniuk@gmail.com>

2019-07-24image: android: allow to wrap uImage into the Android boot imageRoman Stratiienko
This allows to use any available compression format with Android boot image Since not all available compression formats have a magic number we should explicitly specify type of compression. For this purpose using uImage format becomes very useful, as this format is well-known by the community and mkimage tool is already available. Usage example: mkimage -A ARM64 -T kernel -C lzma -d Image.lzma out/kernel At this moment only -C option is handled, but specifying -A and -T options are recommended for compatibility reasons in the future. Kernel that compressed with LZ4 can be already used without wrapping into the uImage, but I recommend wrapping it into the uImage in order to avoid situations when by some mistake legacy LZ4 is used, that is interpreted as raw Image and causes CPU to enter Exception Handler without providing any meaningful explanation to the user.

2019-07-24cmd: part: Add 'number' sub-commandRuslan Trofymenko
This sub-command serves for getting the partition index from partition name. Also it can be used to test the existence of specified partition. Use case: For example, in most CI environments this U-Boot command for automatic testing of Linux rootfs is used: => setenv bootpart 1:f where 0xf is "userdata" partition. But the number of "userdata" partition can be changed any time, when partition table is changed. So it would be nice to get rid of that 0xf magic number and use partition name instead, like this: => part number mmc 1 userdata part_num => setenv bootpart 1:${part_num} Signed-off-by: Ruslan Trofymenko <ruslan.trofymenko@linaro.org> Signed-off-by: Igor Opaniuk <igor.opaniuk@gmail.com> Reviewed-by: Alistair Strachan <astrachan@google.com> Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org>
