Jerome Forissier <jerome.forissier@linaro.org> says:

Miscellaneous fixes made when developing the lwIP series [1]. They are
posted separately since they make sense on their own. Subsequent

effe97d49c at91: rename mem_init() to at91_mem_init()
The AT91-based platforms have a mem_init() function declared in
arch/arm/mach-at91/include/mach/at91_common.h and implemented in various

which also has a global mem_init() function, rename the AT91 one to

6161eaf057 net: gem: Remove undocumented is-internal-pcspma dt flag
Generic understanding/consideration is that phy-mode as sgmi means that the
internal PCS(Physical Coding Sublayer) should be enabled by default.
Xilinx GEM implementation allows configuration GEM (gmii mode) + PL PCS PMA
(sgmii mode, Physical Medum Attachment) but in this case phy-mode should be
setup as gmii.
The reason for this assumption is that phy-mode should be described based
on GEM configuration not based on mode coming out of PHY.

Also Linux kernel automatically setting up PCSSEL bit when phy mode is
sgmii without a need to specified additional DT propety.
All our DTSes with sgmii phy mode have this flag enabled that's why there
is no need/reason to just duplicate information.

10de9b5a6a kbuild: cherry-pick kbuild fdtoverlay changes from linux
Linux commits:
15d16d6dadf6 kbuild: Add generic rule to apply fdtoverlay
44f87191d105 kbuild: parameterize the .o part of suffix-search

The Linux commit 15d16d6dadf6 adds a generic rule in Makefile.lib
to automatically apply fdtoverlay, so that each platform doesn't
need to include a complex rule. This also automatically appends
DTC_FLAGS_foo_base += -@ to all base files

The platform's Makefile only needs to have this now:

foo-dtbs := foo_base.dtb foo_overlay1.dtbo foo_overlay2.dtbo
dtb-y := foo.dtb

effe934e50 imx6q-lxr: Add board support
Add support for the Comvetia i.MX6Q LXR2 board, which is
uses the Phytec PFLA02 SoM.

Based on the original work from Stefano Babic <sbabic@denx.de>.

The Phytec PFLA02 devicetrees are taken from kernel 6.11-rc7.

The imx6q-lxr.dts has been submitted upstream:

https://lore.kernel.org/linux-devicetree/20240913200906.1753458-3-festevam@gmail.com/

After it gets accepted in mainline (most likely in kernel 6.13),
the lxr2 board can then be switched to OF_UPSTREAM and these device trees
can be removed from U-Boot.

c17805e19b Merge patch series "Fix various bugs"
Simon Glass <sjg@chromium.org> says:

This series includes the patches needed to make make the EFI 'boot' test
work. That test has now been split off into a separate series along with
the EFI patches.

This series fixes these problems:
- sandbox memory-mapping conflict with PCI
- the fix for that causes the mbr test to crash as it sets up pointers
  instead of addresses for its 'mmc' commands
- the mmc and read commands which cast addresses to pointers
- a tricky bug to do with USB keyboard and stdio
- a few other minor things

f452e8f092 sandbox: Implement reference counting for address mapping
An address may be mapped twice and unmapped twice. Delete the mapping
only when the last user unmaps it.

Fix a missing comment while here.

e82baf0801 sandbox: Unmap old tags
So far unmapping has not been implemented. This means that if one test
maps a pointer to an address with map_sysmem(), then a second test can
use that same pointer, by mapping the address back to a pointer with
map_to_sysmem(). This is not really desirable, even if it doesn't
cause any problems at the moment.

Implement unmapping, to clean this up.

58f26a17b4 sandbox: Update cpu to use logging
Use log_debug() instead of including the function name in the string.
Add one more debug for PCI.

df2c5941a6 sandbox: Change the range used for memory-mapping tags
Sandbox keeps a table of addresses which map to pointers which are
outside its emulated DRAM. The current range from 10000000 conflicts
with the PCI range, meaning that if PCI mapping is on, that particular
address can be decoded by PCI instead of the table.

Fix this by moving the range up to the top of memory. Update the docs
while we are here.
