33a4dfc703 cmd: sf: prevent overwriting the reserved memory
Added LMB API to prevent SF command from overwriting reserved
memory areas. The current SPI code does not use LMB APIs for
loading data into memory addresses. To resolve this, LMB APIs
were added to check the load address of an SF command and ensure it
does not overwrite reserved memory addresses. Similar checks are
used in TFTP, serial load, and boot code to prevent overwriting
reserved memory.

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.

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

4c5e1ff31b lib: uuid: add UUID v5 support
Add support for generating version 5 UUIDs, these are determistic and work
by hashing a "namespace" UUID together with some unique data. One intended
usecase is to allow for dynamically generate payload UUIDs for UEFI
capsule updates, so that supported boards can have their own UUIDs
without needing to hardcode them.

In addition, move the common bit twiddling code from gen_ran_uuid into a
separate function and rewrite it not to use clrsetbits (which is not
available when building as part of host tools).

Tests for this are added in an upcoming patch.

c6eba28c46 spl: spl_load: fix comparison between negative error code and unsigned size
read could be a negative error value but size in spl_image is unsigned
so when they are compared read is used as if it's a unsigned value
and if it's negative it'll most likely be bigger than size and the
result will be true and _spl_load() will return 0 to the caller.

This results in the caller to _spl_load() not seeing that an error happened
as it should and continuing as if the load was completed when it might
not have been.

Check if read is negative and return it's value if it is before comparing
against size in spl_image.

208fc7a9f9 Merge patch series "provide names for emmc hardware partitions"
Tim Harvey <tharvey@gateworks.com> says:

Modern eMMC v4+ devices have multiple hardware partitions per the JEDEC
specification described as:
 Boot Area Partition 1
 Boot Area Partition 2
 RPMB Partition
 General Purpose Partition 1
 General Purpose Partition 2
 General Purpose Partition 3
 General Purpose Partition 4
 User Data Area

These are referenced by fields in the PARTITION_CONFIG register
(Extended CSD Register 179) which is defined as:
bit 7: reserved
bit 6: BOOT_ACK
  0x0: No boot acknowledge sent (default
  0x1: Boot acknowledge sent during boot operation Bit
bit 5:3: BOOT_PARTITION_ENABLE
  0x0: Device not boot enabled (default)
  0x1: Boot Area partition 1 enabled for boot
  0x2: Boot Area partition 2 enabled for boot
  0x3-0x6: Reserved
  0x7: User area enabled for boot
bit 2:0 PARTITION_ACCESS
  0x0: No access to boot partition (default)
  0x1: Boot Area partition 1
  0x2: Boot Area partition 2
  0x3: Replay Protected Memory Block (RPMB)
  0x4: Access to General Purpose partition 1
  0x5: Access to General Purpose partition 2
  0x6: Access to General Purpose partition 3
  0x7: Access to General Purpose partition 4

Note that setting PARTITION_ACCESS to 0x0 results in selecting the User
Data Area partition.

You can see above that the two fields BOOT_PARTITION_ENABLE and
PARTITION_ACCESS do not use the same enumerated values.

U-Boot uses a set of macros to access fields of the PARTITION_CONFIG
register:
EXT_CSD_BOOT_ACK_ENABLE                 (1 << 6)
EXT_CSD_BOOT_PARTITION_ENABLE           (1 << 3)
EXT_CSD_PARTITION_ACCESS_ENABLE         (1 << 0)
EXT_CSD_PARTITION_ACCESS_DISABLE        (0 << 0)

EXT_CSD_BOOT_ACK(x)             (x << 6)
EXT_CSD_BOOT_PART_NUM(x)        (x << 3)
EXT_CSD_PARTITION_ACCESS(x)     (x << 0)

EXT_CSD_EXTRACT_BOOT_ACK(x) (((x) >> 6) & 0x1)
EXT_CSD_EXTRACT_BOOT_PART(x) (((x) >> 3) & 0x7)
EXT_CSD_EXTRACT_PARTITION_ACCESS(x) ((x) & 0x7)

There are various places in U-Boot where the BOOT_PARTITION_ENABLE field
is accessed via EXT_CSD_EXTRACT_PARTITION_ACCESS and converted to a
hardware partition consistent with the definition of the
PARTITION_ACCESS field used by the various mmc_switch incarnations.

To add some sanity to the distinction between BOOT_PARTITION_ENABLE
(used to specify the active device on power-cycle) and PARTITION_ACCESS
(used to switch between hardware partitions) create two enumerated types
and use them wherever struct mmc * part_config is used or the above
macros are used.

Additionally provide arrays of the field names and allow those to be
used in the 'mmc partconf' command and in board support files.

The first patch adds enumerated types and makes use of them which
represents no compiled code change.

The 2nd patch adds the array of names and uses them in the 'mmc
partconf' command.

The 3rd patch uses the array of hardware partition names in a board
support file to show what emmc hardware partition U-Boot is being loaded
from.

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).

6534d26ee9 lmb: do away with arch_lmb_reserve()
All of the current definitions of arch_lmb_reserve() are doing the
same thing -- reserve the region of memory occupied by U-Boot,
starting from the current stack address to the ram_top. Introduce a
function lmb_reserve_uboot_region() which does this, and do away with
the arch_lmb_reserve() function.

Instead of using the current value of stack pointer for starting the
reserved region, have a fixed value, considering the stack size config
value.

With the move to make the LMB allocations persistent and the common
memory regions being reserved during board init, there is no need for
an explicit reservation of a memory range. Remove the

5e9553cc72 lmb: allow for resizing lmb regions
Allow for resizing of LMB regions if the region attributes match. The
current code returns a failure status on detecting an overlapping
address. This worked up until now since the LMB calls were not
persistent and global -- the LMB memory map was specific and private
to a given caller of the LMB API's.

With the change in the LMB code to make the LMB reservations
persistent, there needs to be a check on whether the memory region can
be resized, and then do it if so. To distinguish between memory that
cannot be resized, add a new flag, LMB_NOOVERWRITE. Reserving a region
of memory with this attribute would indicate that the region cannot be
resized.

ed17a33fed lmb: make LMB memory map persistent and global
The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

Philip Oberfichtner <pro@denx.de> says:

This patch series implements the dwc_eth_qos glue driver for Intel SOCs.
Before doing that, a few general adaptions to the dwc_eth_qos.c main
driver are required. Most notably, the preparation for PCI based driver
instances, which do not necessarily use a device tree.
