Merge patch series "Introduce ICSSG Ethernet driver"
MD Danish Anwar <danishanwar@ti.com> says:
Introduce ICSSG PRUETH support in uboot. The ICSSG driver is used in TI
AM654 SR2.0.
The ICSSG PRU Sub-system runs on EMAC firmware. This series Introduces
support for ICSSG driver in uboot.
This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.
To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC
cores and RPROC cores need to be booted with the firmware. This step is
done inside driver similar to kernel.
The remoteproc driver uses request_fw_into_buf() API from fs-loader driver
to load and start rproc with the required firmwares.
This series only introduces driver files. The device tree and config
changes to enable ICSSG driver will be introduced later.
net: ti: icssg: Add support sending FDB command to update rx_flow_id

two slices per instance. This driver caters to both slices / ports of
the icssg subsystem.
Since it is not possible for Ethernet driver to register more than one
port for a given instance, this patch introduces top level PRUETH as
UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support
bringing up more than one Ethernet interface in U-Boot.

zlib: Remove incorrect ZLIB_VERSION
Get rid of zlib version which is not correct because of U-Boot related
changes and various CVE backports.
The change in inspired by Linux kernel commit 4f3865fb57a0 ("[PATCH]
zlib_inflate: Upgrade library code to a recent version") which described
ZLIB_VERSION removal as
"This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us. This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version."
Author describes wish to follow this guidance at
https://www.zlib.net/zlib_faq.html#faq24:
"The license says that altered source versions must be "plainly marked". So
what exactly do I need to do to meet that requirement?
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
particular, the final version number needs to be changed to f, and an
identification string should be appended to ZLIB_VERSION. Version numbers
x.x.x.f are reserved for modifications to zlib by others than the zlib
maintainers. For example, if the version of the base zlib you are altering
is 1.2.3.4, then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
ZLIB_VERSION to something like 1.2.3.f-zachary-mods-v3. You can also update
the version strings in deflate.c and inftrees.c."
But U-Boot is not exact version that's why following the same style which
has been used by Linux kernel where ZLIB_VERSION is completely removed.

fdt: Fix fdt_pack_reg() on 64-bit platforms
When "memory" node is being processed in fdt_pack_reg() on ARM64
platforms, an unaligned bus access might happen, which leads to
"synchronous abort" CPU exception. Consider next dts example:
After fdt_pack_reg() reads the first addr/size entry from such memory
node, the "p" pointer becomes 12 bytes shifted from its original value
(8 bytes for two address cells + 4 bytes for one size cell). So now it's
not 64-bit aligned, and an attempt to do 64-bit bus access to that
address will cause an abort like this:
"Synchronous Abort" handler, esr 0x96000021, far 0xba235efc
This issue was originally reported by David Virag [1] who observed it
happening on Samsung Exynos7885 SoC (ARM64), and later the same issue
was observed on Samsung Exynos850 (ARM64).
Fix the issue by using put_unaligned_be64() helper, which takes care of
possible unaligned 64-bit accesses. That solution was proposed by Simon
Glass in the original thread [1].

part: Check all partitions in part_get_info_by_name()
In part_get_info_by_name() the inability to get some partition info
shouldn't be a reason for dropping out of the loop. That might happen
e.g. if the partition is hidden or unused. An example of such case are
Samsung devices, where they use the "unused" GUID type
(00000000-0000-0000-0000-000000000000) to indicate that the partition
should be hidden from the OS. Such partitions might not be seen in
"part list" output, which creates "gaps" in numbering in between of the
visible partitions:
Part Start LBA End LBA Name

5 0x00026420 0x00026c1f "dtbo"
12 0x0003f390 0x0074738f "super"
In that case, the loop in part_get_info_by_name() would break after
partition #1, so any attempt to obtain "dtbo" or "super" partition will
fail. Fix that by continuing to iterate over the remaining partitions to
make sure none of the visible ones is missed. That makes "part" command

In NFSv3 file handles have a variable length up to 64 bytes. This is
also true for the MOUNT protocol. [1]
When the NFSv3 server replies with a file handle length > 32 bytes, U-Boot
only copies 32 bytes of that file handle and the next LOOKUP Call fails:
BIOS> nfs ${loadaddr} 192.168.1.51:/nfsroot/opos93dev-br/boot/Image
Using ethernet@428a0000 device
File transfer via NFS from server 192.168.1.51; our IP address is 192.168.1.133
Filename '/nfsroot/opos93dev-br/boot/Image'.
Load address: 0x80400000
Loading: *** ERROR: File lookup fail
done
BIOS>
Looking at this transfer in Wireshark, we can see that the server
replies with the following file handle:
Open for reading as O_RDONLY instead of O_RDWR:
the only usage of the fd is for the single read() below;
this prevented
mkimage -f auto -A arm64 \
-T kernel -C lz4 -d Image-6.6.15.lz4 \
-b mt8173-elm-hana-6.6.15.dtb outf
when the inputs were unwritable.
fs: ext4: make "File System is consistent\n" a debug message
When accessing an ext2 system the message "File System is consistent\n" is
shown after each write. This is superfluous noise. Only write a debug
message.

build: Revive and update LDR format support
LDR format files are used primarily by Analog Devices processors but may
be of interest to other vendors. Previously support existed for this
format as part of the U-Boot build, but it has been unmaintained and
unused for a long time. In preparation for adding support for modern ADI
processors that use LDR, modernize the LDR support:
- Introduce CONFIG_LDR_CPU as the CPU string recognized by the LDR tool
may not be the same as CONFIG_CPU
- Add an SPL target that repackages u-boot-spl inside an LDR file
An almost identical target for packaging u-boot into an LDR file already
exists and did not need to be created.

scripts/Makefile.spl: Use 'sort' in SHRUNK_ARCH_DTB rule
With configs such as "am64x_evm_a53" or "imx8mp_venice" which list
multiple device trees to build we get a warning such as:
scripts/Makefile.spl:578: target 'spl/dts/freescale/' given more than once in the same rule
If we sort this list first the warning goes away.
