getting-started: document flashing SpacemiT boards with TitanFlasher - #1699
Document how SpacemiT boards are flashed when the bootloader lives in SPI NOR flash. These boards may not boot from removable media, so the image is written to the UFS storage with SpacemiT's TitanFlasher over USB.
The new section in Writing the image covers:
splitting the Armbian image into bootfs and rootfs partition images
loading the vendor firmware package in TitanFlasher and replacing only those two partitions,
keeping the SPI NOR bootloader in place, and restoring it only when the vendor firmware must be updated,
the 4 KiB sector requirement of the UFS.
Two screenshots show the TitanFlasher partition list and the partition file dialog.
The section is written for SpacemiT boards in general the Firefly AIBOX-K3 is used as the example.

Walkthrough
The getting-started guide adds steps to prepare and flash an AIBOX-K3 image to UFS with TitanTools and TitanFlasher. It describes entering USB download mode, replacing the bootfs and rootfs partitions, and completing the flash before disconnecting or powering off. It also documents optional SPI NOR bootloader restoration, the 4 KiB sector requirement, and vendor documentation links. The introductory sentence no longer has trailing whitespace.
This documentation-only change adds a guide for flashing SpacemiT boards to UFS with TitanFlasher. The earlier problems with the broken code fence, sector size, USB port, link and wait-for-completion step are corrected in the current text. No concrete merge-blocking issue remains. The exact TitanFlasher partition-row behavior is unconfirmed, and the author tested on an AIBOX-K3.

- Around line 190-191: Update the MaskRom instructions to specify connecting the
PC to the Type-C USB 3.0 port, not the USB serial port, before holding Boot and
applying 12 V power; preserve this order so TitanFlasher can detect the board.
- Line 223: Update the Firefly AIBOX-K3 firmware upgrade guide link to point to
the vendor’s current AIBOX-K3 USB upgrade page, keeping the surrounding
documentation and link text unchanged.
- Line 180: Update the dd command in the image-writing instructions to limit
extraction to the rootfs partition by adding a count equal to its size in MiB,
preserving the existing input file, output file, block size, and skip value.

- Describe the vendor tool flow used by boards whose bootloader lives in
SPI NOR: prepare the vendor firmware, replace the bootfs and rootfs
partitions with an Armbian image, and keep the other partitions only
when the vendor bootloader must be restored.
