Qualcomm peripherals like UART, SPI, I2C, etc are all exposed under a
common GENI Serial Engine wrapper device. Replace the stub driver we use
for this currently with a full-on misc device and implement support for
loading peripheral firmware.
Each of the peripherals has it's own protocol-specific firmware, this is
stored on the internal storage of the device with a well-known partition
type GUID.
To support this, GENI will bind peripherals in two stages. First the
ones that already have firmware loaded (such as the serial port) are
bound in the typical way. But devices that require firmware loading are
deferred until EVT_LAST_STAGE_INIT. At this point we can be sure that
the storage device is available, so we load the firmware and then bind
and probe the remaining children.
Child devices are expected to determine if firmware loading is necessary
and call qcom_geni_load_firmware().
Since Linux currently doesn't support loading firmware (and firmware may
not be available), we probe all GENI peripherals to ensure that they
always load firmware if necessary.

means setting the 'srk_revoke_mask' option in the config file used to
sign the boot container. The 'ahab_commit 0x10' can then be used to commit

The MediaTek MT7987/MT7988 SoCs features a built-in 2.5Gb PHY
connected to GMAC1. The PHY supports 10/100/1000/2500 Mbps
full-duplex only.
The PHY requires one or two firmware files. Firmware for MT7988 has
already been added to upstream: mediatek/mt7988/i2p5ge-phy-pmb.bin.
MT7987 has two firmware files which will be add to upstream later:
i2p5ge-phy-pmb.bin and i2p5ge-phy-DSPBitTb.bin.
Environment variable can be set for firmware data loading:
mt7987_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin
mt7987_i2p5ge_load_dspbit_firmware for i2p5ge-phy-DSPBitTb.bin
mt7988_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin
This driver allows dedicated weak functions to be overridden by
board to provide the firmware data:
mt7987_i2p5ge_get_fw() for MT7987
mt7988_i2p5ge_get_fw() for MT7988

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.

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.
The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.
On x86, QEMU provides the tables in a mapped memory region and U-Boot
makes use of these directly, thus making it difficult to use any common
code.
Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.
On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.

Raymond Mao <raymond.mao@linaro.org> says:
Motivations for changes:
Current SMBIOS library and command-line tool is not fully matching with
the requirements:
1. Missing support for other mandatory types (#7, #9, #16, #17, #19).
2. Only a few platforms support SMBIOS node from the device tree.
3. Values of some fields are hardcoded in the library other than fetching
from the device hardware.
4. Embedded data with dynamic length is not supported (E.g. Contained
Object Handles in Type #2 and Contained Elements in Type #3)
Changes:
1. Refactor the SMBIOS library and command-line tool to better align with
the SMBIOS spec.
2. Create an arch-specific driver for all aarch64-based platforms to fetch
SMBIOS private data from the device hardware (processor and cache).
3. Create a sysinfo driver to poppulate platform SMBIOS private data.
4. Add generic SMBIOS DTS file for arm64 platforms for those common strings
and values which cannot be retrieved from the system registers.
Vendors can create their own SMBIOS node using this as an example.
For those boards without SMBIOS nodes, this DTS file can be included to
have a generic SMBIOS information of the system.
5. Add support for Type #7 (Cache Information) and link its handles to
Type #4.
6. To minimize size-growth for those platforms which have not sufficient
ROM spaces or the platforms which don't need detailed SMBIOS
information, new added fields are only being built when kconfig
GENERATE_SMBIOS_TABLE_VERBOSE is selected.
Once this patch is acceptted, subsequent patch sets will add other missing
types (#9, #16, #17, #19).
Tests:
To test this with QEMU arm64, please follow the guide on dt_qemu.rst to
get a merged DT to run with.
