misc: fs_loader: Add request_firmware_into_buf_via_script() for flexible firmware loading via U-Boot script
This commit introduces a new API,
request_firmware_into_buf_via_script(), to the fs_loader framework.
This function allows firmware to be loaded into memory using
a user-defined U-Boot script, providing greater flexibility for
firmware loading scenarios that cannot be handled by static file
paths or device/partition selection alone.
Key features:
- The API runs a specified U-Boot script (by name), which is responsible
for loading the firmware into memory by any means (e.g., load from MMC, USB, network, etc.).
- The script must set two environment variables: 'fw_addr'
(the memory address where the firmware is loaded) and
'fw_size' (the size of the firmware in bytes).
- The function validates these variables, copies the firmware into a newly
allocated buffer (using memdup), and returns the pointer
via the provided double pointer argument.
- The maximum allowed firmware size is checked to prevent buffer overflows.
- The environment variables are cleared after use to avoid stale data.
- Detailed error messages are provided for all failure conditions to aid debugging.
Usage example:
1. Define a U-Boot script in the environment that loads the firmware
and sets the required variables:
=> env set my_fw_script 'load mmc 0:1 ${loadaddr} firmware.bin &&
env set fw_addr ${loadaddr} && env set fw_size ${filesize}'
2. In your code, call the new API:
void *fw_buf = NULL;
int ret = request_firmware_into_buf_via_script(&fw_buf, 0x46000000, "my_fw_script");
if (ret < 0)
return ret;
This approach allows board integrators and users to customize the firmware
loading process without modifying the source code,
simply by changing the script in the U-Boot environment.

The existing compatible name for U-Boot's k3 system controller driver
i.e "ti,am625-system-controller" has been added to linux[1] device-tree.
This compatible in kernel is meant for configuring the Control Module
registers (CTRL_MMR0).
However in U-Boot, the matching driver was being used to load the system
firmware on the secure M-cores by the R5 SPL and therefore must be
updated to a different compatible to avoid conflicts.
Therefore, this patch renames all references of the compatible to
"ti,am654-tisci-rproc-r5". The "-r5" is appended so as to avoid any
future conflicts since r5 specific compatibles should only be useful for

mtd: nand: cadence: Fix device assignment to avoid warm reset issue
The driver currently does:
mtd->dev->parent = cadence->dev;
This works in Linux because `struct mtd_info` embeds a `struct device`,
so `mtd->dev` is always valid and its `.parent` can be set.
In U-Boot, however, `mtd->dev` is only a pointer to a `struct udevice`.
Dereferencing it before assignment is invalid, which breaks the device
hierarchy. As a result, consumers relying on `mtd->dev` (e.g. partition
parser, reset and re-init paths) operate on a dangling pointer. This
leads to failures during warm reset when the NAND device is accessed
again.
Fix by assigning the device pointer directly:
mtd->dev = cadence->dev;
This matches U-Boot’s device model, preserves a valid hierarchy, and
resolves the warm reset issue on Cadence NAND.

board: phytec: phycore-imx93: Fix EEPROM bus mismatch in SPL
Fix PHYTEC EEPROM bus mismatch between SPL and U-Boot proper by enabling
CONFIG_SPL_DM_SEQ_ALIAS=y on phyCORE-i.MX93 boards. This way, both the
SPL and U-Boot proper will respect the device-tree aliases for I2C devs
and use the same I2C bus number for phytec_eeprom_data_setup() function
calls. This makes code less confusing and more robust.
Fixes an issue apparent since commit
79f3e77133bd ("Subtree merge tag
'v6.16-dts' of dts repo [1] into dts/upstream") where SPL would spew the
following error:
phytec_eeprom_read: i2c EEPROM not found: -110.
phytec_eeprom_data_setup: EEPROM data init failed
While later in U-Boot proper, EEPROM would be successfully read out.
This happens because Linux device-tree for phyBOARD-Segin-i.MX93 since
aforementioned commit enables I2C bus 2 (lpi2c2 is used for audio codec
and RTC) which breaks SPL I2C bus number ordering and I2C EEPROM bus is
shifted by +1. Now, lets prevent this from happening again by utilizing
device-tree aliases also in the SPL.

Neha Malcom Francis <n-francis@ti.com> says:
Currently, the inline ECC implementation enables inline ECC across the
entire DDR space. However this is not always required and a more common
ask is to have only a portion of the DDR protected as enabling ECC
impacts read/write performance metrics.
This series aims to modify the logic to firstly support partial inline
ECC in its' most basic form which works for single controllers. Then it
introduces an algorithm to support multi DDR controllers where
interleaving plays a role. Since interleaving is handled by the MSMC, it
only makes sense to have the MSMC decide the inline ECC ranges for each
DDR.
This series also introduces support for multiple partial regions of inline
ECC however due to complexity only support for single DDR is present now.
WIP: A commandline test case patch for verifying the correct behaviour
of inline ECC including partial case. Was targeted for v2 however a little
tricky to make it a general test case especially for multi-DDR cases, so
have not combined it in this series for now.
Testing:
- Memtester runs for J721S2 and J784S4 platforms with and without ECC
enablement runs fine.
- Along with patches that add support for the commandline test (see WIP
note above) J784S4 shows expected behavior for three sets of partial
inline ECC regions (non-overlapping, and after modifying J784S4 to
have single DDR instead of multi-DDR):

ram: k3-ddrss: Support multiple ECC regions for a single controller
K3 Inline ECC mechanism can support up to 3 regions of inline ECC, add

The existing approach does not account for interleaving in the DDRs when
setting up regions. There is support for MSMC to calculate the regions
for each DDR, so modify k3_ddrss_probe to set the regions accordingly
for multi-DDR systems.

Add support for calculation of the protected regions for each DDR in
multi-DDR systems. Since MSMC is the parent node of the individual DDRs
as well as responsible for their interleaving, it only makes sense for
MSMC to contain the logic for dividing the regions.

In K3 multi-DDR systems, the MSMC is responsible for the interleave
mechanism across all the DDR controllers. Add support for MSMC to obtain
the number of controllers it's responsible for using the DT.

As we increase the functionalities that the K3 DDRSS sub-system support,
it is becoming more evident that the same logic cannot apply to both
single as well as multiple DDR controller devices. Add
CONFIG_K3_MULTI_DDR to be used to differentiate between the two.

Instead of defaulting to choosing the entire DDR region when enabling

Let ecc_regions[x].start reflect the start of the ECC region in terms of

systems as well.
