To quote the author: This series adds support for running valgrind against U-Boot's internal malloc. This allows for much more useful reports to be generated. Some example output of valgrind run against u-boot/master with this branch applied may be found at [1]. Note that valgrind gives up around acpi. This feature still needs a lot of work on suppressions/hints to filter out the noise properly.

This annotates malloc and friends so that valgrind can track the heap. To do this, we need to follow a few rules: * Call VALGRIND_MALLOCLIKE_BLOCK whenever we malloc something * Call VALGRIND_FREELIKE_BLOCK whenever we free something (generally after we have done our bookkeeping) * Call VALGRIND_RESIZEINPLACE_BLOCK whenever we change the size of an allocation. We don't record the original request size of a block, and neither does valgrind. For this reason, we pretend that the old size of the allocation was for 0 bytes. This marks the whole allocaton as undefined, so in order to mark all bits correctly, we must make the whole new allocation defined with VALGRIND_MAKE_MEM_DEFINED. This may cause us to miss some invalid reads, but there is no way to detect these without recording the original size of the allocation. In addition to the above, dlmalloc itself tends to make a lot of accesses which we know are safe, but which would be unsafe outside of dlmalloc. For this reason, we provide a suppression file which ignores errors ocurring in dlmalloc.c Signed-off-by:

Valgrind uses magic code sequences to define an ABI that the client may use to request behavior from the host. In particular, this may be used to inform valgrind about custom allocators, such as the one used in U-Boot. This adds headers defining these sequences to U-Boot. It also adds a config option to disable emission of these sequences entirely, in the (likely) event that the user does not wish to use valgrind. Note that this option is called NVALGRIND upstream, but was renamed (and inverted) to CONFIG_VALGRIND. Aside from this and the conversion of a few instances of VALGRIND_DO_CLIENT_REQUEST_EXPR to STMT, these headers are unmodified. These headers were copied from valgrind 3.16.1-4 as distributed in Arch Linux. They are licensed with the bzip2 1.16 license. This appears to be a BSD license with some clauses from Zlib.

This reverts commit 8d61237e. This commit broke environment on literally every board I have access to, with this revert in place, environment works as it should again. The problem I observe with this patch is that saved environment in either SPI NOR or eMMC is never used, the system always falls back to default environment. The 'saveenv' command does succeed, but then after reset, the default env is again used. Furthermore, the commit introduced duplicate code in env_init(), this: " if (!prio) { gd->env_addr = (ulong)&default_environment[0]; gd->env_valid = ENV_INVALID; return 0; } if (ret == -ENOENT) { gd->env_addr = (ulong)&default_environment[0]; gd->env_valid = ENV_INVALID; return 0; } " Furthermore, the commit is missing DCO SoB line. Also note that upstream does not support UltraZed EG board, so this might have been a patch pulled from downstream which did depend on some other downstream behavior. Signed-off-by:

With dm-tag feature, any U-Boot subsystem is allowed to associate arbitrary number of data with a particular udevice. This can been see as expanding "struct udevice" without modifying the definition. As a first user, UEFI subsystem makes use of tags to associate an efi_disk object with a block device. Signed-off-by:

virtio_init() enumerates all the peripherals that are to be materialised with udevices(UCLASS_VIRIO) and creates particular device instances (UCLASS_BlK or whatever else) as children. On the other hand, device_probe() won't be invoked against those resultant udevices unlike other ordinary device drivers do in the driver model. This is particularly inconvenient when we want to add "event notification" callback so that we will be able to automatically create all efi_disk objects in a later patch. With this patch applied, "virtio scan" will work in a similar way to "scsi rescan", "usb start" or others in term of 'probe' semantics. I didn't add this change to virtio_init() itself because this function may be called in board_init_r() (indirectly in board_late_init()) before UEFI subsustem is initialized. Signed-off-by:
