+system.  Signature written by minisign can be verified using OpenBSD's
+signify tool: public key files and signature files are compatible.  However,
+minisign uses a slightly different format to store secret keys.  Minisign
+signatures include trusted comments in addition to untrusted comments.
+Trusted comments are signed, thus verified, before being displayed.")

+Subject: [PATCH 1/2] build_macros: Add mechanism to prevent bin generation.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On certain platforms it does not make sense to generate
+TF-A binary images. For example a platform could make use of serveral
+memory areas, which are non-continuous and the resulting binary
+therefore would suffer from the padding-bytes.
+Typically these platforms use the ELF image.
+
+This patch introduces a variable DISABLE_BIN_GENERATION, which
+can be set to '1' in the platform makefile to prevent the binary
+generation.

+Subject: [PATCH 2/2] rockchip: Disable binary generation for all SoCs.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
+have non-continuous memory areas in the linker script with a huge
+gap between them. This results in extremely padded binary images
+with a size of about 4 GiB.
+
+E.g. on the RK3399 we have the following memory areas (and base addresses):
+RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).
+
+Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
+use the ELF image instead, which has a size of a few hundred kBs.
+
+In order to prevent the generation of a huge and useless file,
+this patch disables the binary generation for all affected Rockchip
+SoCs.

+Subject: [PATCH] vircgroup: Ensure /machine group is associated with its
+ parent.
+
+Call first virCgroupNew on the parent group virCgroupNewPartition if
+it is available on before the creation of the child group.  This
+ensures that the creation of a first level group on the unified
+architecture, as the check at virCgroupV2ParseControllersFile as the
+parent file is there.

+PSM2 is the only valid implementation for OmniPath (OPA).  UCX also
+supports OmniPath, but it does so via Verbs, thus getting much lower
+performance (typically 3 GiB/s instead of 10 GiB/s).
+
+To work around that, give the mtl_psm2 component a higher priority
+than the pml_ucx component.

-Subject: [PATCH] Rework the growing algorithm
-
-On ARM systems there is no space in virtual memory for another LOAD
-area in front of the code LOAD area. So insert data to its end
-instead. At this location there should be enough space in virtual
-memory due to alignment. We can extend it until the end of the
-alignment but the file shift may be greater as it must be aligned
-to the page size. Do the same for the data LOAD area.

+
+A Flags-type variable without any flag set can be replaced with 0, so
+this is a safe thing to do. It also prevents us from having to deal with
+the accidental API break in libsecret (see

+Subject: [PATCH] input/item: sort before attaching slaves
+
+The order of readdir() is completely filesystem dependent.
+
+Slaves should be attached using the same order across multiple OSses/access
+modules.
+
+This fixes the test_libvlc_slaves on some system when the entry order from
+readdir() is different.
+
+This patch need to be backported to VLC 3.0.
