PCA9450 PMIC supports reading the reset status from the PWRON_STAT
register. Bits 7-4 give indication of the PMIC reset cause:
- PWRON (BIT7) - Power ON triggered by PMIC_ON_REQ input line,
- WDOGB (BIT6) - Boot after cold reset by WDOGB pin (watchdog reset),
- SW_RST (BIT5) - Boot after cold reset initiated by the software,
- PMIC_RST (BIT4) - Boot after PMIC_RST_B input line trigger.
Add support for reading reset status via the sysreset framework in a
convenient printable format.

The family of PCA9450 PMICs have the ability to perform system resets.
Restarting via PMIC is preferred method of restarting the system as all
the peripherals are brought to a know state after a power-cycle. The
PCA9450 features a cold restart procedure which is initiated by an I2C
command 0x14 to the SW_RST register.
Support in Linux for restarting via PCA9450 PMIC has been added by
Linux commit 6157e62b07d9 ("regulator: pca9450: Add restart handler").
Now add support for it also in the U-Boot via sysreset framework.

this to have the legacy portions in their own header, which should not

The RK806 PMIC has a bitfield for configuring the restart/reset behavior
(which I assume Rockchip calls "function") whenever the PMIC is reset
either programmatically (c.f. DEV_RST in the datasheet) or via PWRCTRL
or RESETB pins.
For RK806, the following values are possible for RST_FUN:
0b00 means "Restart PMU"
0b01 means "Reset all the power off reset registers, forcing
the state to switch to ACTIVE mode"
0b10 means "Reset all the power off reset registers, forcing
the state to switch to ACTIVE mode, and simultaneously
pull down the RESETB PIN for 5mS before releasing"
0b11 means the same as for 0b10 just above.
This adds the appropriate logic in the driver to parse the new
rockchip,reset-mode DT property to pass this information. It just
happens that the values in the binding match the values to write in the
bitfield so no mapping is necessary.
For backward compatibility reasons, if the property is missing we set it
to 0b10 (i.e. BIT(7)) like before this commit was merged instead of
leaving it untouched like in the kernel driver.
Note that this does nothing useful for U-Boot at the moment as the ways
to reset the device (e.g. via `reset` command) doesn't interact with the
RK8xx PMIC and simply does a CPU reset.
Considering the upstream Linux kernel left this register untouched until
(assumed) v6.17[1], this is useful for cases in which the U-Boot
bootloader has this patch (and running with a DT with
rockchip,reset-mode property set) and running an upstream kernel before
(assumed) v6.17, or alternatively later without the property in the
kernel DT.

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 legacy network stack sets net_try_count to 1 at the beginning of the
net_loop() function. This is required for net_start_again() to work
properly. Therefore, set the variable accordingly in the do_ping()
function when NET_LWIP=y. This fixes an issue where a ping to an
unreachable destination would run twice on the same network device. For
example with qemu_arm64_lwip_defconfig:
=> dhcp
DHCP client bound to address 10.0.2.15 (3 ms)
=> ping 10.0.0.1
Using virtio-net#32 device

SPL checks for a magic word in the system manager's scratch
register to determine if an L2 reset has occurred. If detected,
SPL places all slave CPUs (CPU1–3) into WFI mode. The master
CPU (CPU0) then initiates a warm reset by writing to the RMR_EL3
system register and also enters WFI mode.
This warm reset flow is handled entirely within the HPS. The
function `socfpga_sysreset_request()` triggers the warm
reset, and upon SPL re-entry, the updated `lowlevel_init_soc64.S`
handles the necessary initialization.
