4c6f2ab29a board: bcm96846: Enable NAND options
This adds reasonable NAND options to the BCM96846 reference design:

- CMD_NAND, MTD_RAW_NAND
- Disable SYS_NAND_ONFI_DETECTION as this just give error messages
- MTD, MTDPARTS with DM and related config options
- CMD_UBI and CMD_UBIFS as this is likely used with ubi/ubifs

What I didn't add was something like the following:

CONFIG_MTDPARTS_DEFAULT="nand0:256k(cfi),257024k(image)"

Because I don't actually have a BCM96846 reference design. These
are only available to Broadcom and their customers  I think,
but perhaps the people at Broadcom can provide the detail of
the flash layout for BCM96846 so we can add this too so the
bcm96846_config is usable out of the box.

2f7ab49644 sunxi: Add support for Anbernic RG35XX-2024
The Anbernic RG35XX series of devices are based around an Allwinner
H700 SoC with 1GB of RAM, 2 SD cards, and multiple input buttons.

This bootloader has been tested on the Anbernic RG35XX-2024 and
RG35XX-H, but should be suitable for the entire lineup of H700 based
devices.

A future series of updates will add board selection logic to identify
and load the correct device tree automatically.

9c4b44d1e3 sunxi: H616: switch to OF_UPSTREAM
With the recent "old-style sunxi" sync and the penultimate OF_UPSTREAM DT
update, both directories were based on the same v6.10 kernel tree.
And while there is one subtle difference in many Allwinner SoC's DT
files, the H616 ones turn out to be identical.

Remove the old copies of the H616 related .dts and .dtsi files, and
switch the whole H616 SoC over to use OF_UPSTREAM. This immediately
benefits from the recent upstream DT update, to kernel v6.11.

f8efc68b30 Merge patch series "spi-nor: Add parallel and stacked memories support"
Venkatesh Yadav Abbarapu <venkatesh.abbarapu@amd.com> says:

This series adds support for Xilinx qspi parallel and
stacked memeories.

In parallel mode, the current implementation assumes that a maximum
of two flashes are connected. The QSPI controller splits the data
evenly between both the flashes so, both the flashes that are connected
in parallel mode should be identical.
During each operation SPI-NOR sets 0th bit for CS0 & 1st bit for CS1 in
nor->flags.

In stacked mode the current implementation assumes that a maximum of two
flashes are connected and both the flashes are of same make but can differ
in sizes. So, except the sizes all other flash parameters of both the flashes
are identical.

Spi-nor will pass on the appropriate flash select flag to low level driver,
and it will select pass all the data to that particular flash.

Write operation in parallel mode are performed in page size * 2 chunks as
each write operation results in writing both the flashes. For doubling the
address space each operation is performed at addr/2 flash offset, where addr
is the address specified by the user.

Similarly for read and erase operations it will read from both flashes, so
size and offset are divided by 2 and send to flash.

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

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.

a01ed791c9 qcom_defconfig: bump CONFIG_NR_DRAM_BANKS
Some newer boards end up with a bunch of holes in the memory map due to
how Qualcomm's hypervisor and ABL work. The end result is 14+ memory
regions.

Bump CONFIG_NR_DRAM_BANKS to 24 so we can handle these and any future
expansion easily.

Yes, this is ridiculous, but there is no other way.

360aaddd9c Merge patch series "Make LMB memory map global and persistent"
Sughosh Ganu <sughosh.ganu@linaro.org> says:

This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.

This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.

The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.

The tests have been tweaked where needed because of these changes.

The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.

Notes:

1) These patches are on next, as the alist patches have been
   applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
   get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
   (ideally an 85xx, as I do not have one).

5c146457c7 sandbox: spl: enable lmb config for SPL
Enable the LMB config in SPL. This helps in testing the LMB code in
SPL on sandbox.
