The Radxa ROCK 4D is a compact single-board computer (SBC) featuring
numerous top-tier functions, features, and expansion options.
Equipped with the Rockchip RK3576 or RK3576J SoC, the ROCK 4D boasts an
octa-core CPU (4x Cortex-A72 + 4x Cortex-A53), Mali-G52 GPU, and a
powerful 6 TOPS NPU, making it ideal for AI and multimedia tasks.
Features tested on a Radxa ROCK 4D v1.112:
- SPI Flash boot
- Ethernet
- PCIe/NVMe
- USB host
ROCK 4D boards with SPI Flash is configured to boot from FSPI0->UFS->USB,
or directly from USB when the MASKROM button is pressed, booting
directly from SD-card is not possible on these boards.

The bootsource ids reported by BootROM of RK3576 for SPI NOR and USB
differs slightly compared to prior SoCs:
- Booting from sfc0 (ROCK 4D) report the normal bootsource id 0x3.
- Booting from sfc1 M1 (NanoPi M5) report a new bootsource id 0x23.
- Booting from sfc1 M0 has not been tested (no board using this config).
- Booting from USB report a new bootsource id 0x81.
Add a RK3576 specific read_brom_bootsource_id() function to help decode
the new bootsource id values and the required boot_devices mapping of
sfc0 and sfc1 to help support booting from SPI flash on RK3576.

* Initial support for SDM670 (similar to SDM845), SM6350, and SM7150
platforms is added
* USB and UART issues on MSM8916 are addressed (improving stability/
reliability)
* Firmware loading is implemented for the GENI serial engine, this is
used on some platforms to load firmware for i2c/spi/uart to work
Some additional patches like binman support for building MBN files still
need some additional work.

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.

This board is very tight on space in SPL; in fact with my compiler it
ends up just exactly on the wrong side:
spl/u-boot-spl.bin exceeds file size limit:
limit: 0xa000 bytes
actual: 0xa014 bytes
excess: 0x14 bytes
The repeated "lookup and request" pattern in spl_board_init() suggests
a low-hanging fruit for reducing the code size. This reduces the
object size of spl/board/liebherr/btt/btt.o by 300 bytes.
I've left the lack of error handling as-is; there isn't really
anything to do if it fails, so I suppose the printfs are the best that
can be done.
