The extlinux.conf provides a standard U-Boot distro boot configuration
that allows boards with U-Boot already flashed to SPI NOR to boot
without needing the boot.scr script. U-Boot scans for this file at
/extlinux/extlinux.conf during its distro boot sequence.
This is the fallback when U-Boot is already on SPI and the boot
partition provides the kernel/DTB/ramdisk for Android TV.

Remove unused OPI_BOOT_OUT staging directory. Boot.img is now
just the U-Boot binary for build system packaging. The actual
FAT32 boot partition with kernel/DTB/ramdisk is created by
mkimg_gpt.sh, which runs outside the build system and has
access to mkfs.vfat and mcopy.

- Make mkimg_gpt.sh executable (chmod +x)
- Fix boot partition creation: create FAT32 fs and copy kernel/boot
files instead of relying on boot.img (which was the u-boot binary)
- Add android-sdcard.dtbo to boot partition
- Parameterize DEVICE_PATH and KERNEL_PATH variables
- Use correct U-Boot path (new Ultra-specific bl32less binary)
The boot partition (p1) is now properly created as FAT32 with
kernel Image, DTB, boot.scr, ramdisk.img, and config.txt.
This matches what U-Boot expects to read from the boot media.

mkfs.fat and mcopy are disallowed in Android 16 build system.
Use pre-built U-Boot binary as boot.img for packaging purposes.
The actual bootable image is created by mkimg_gpt.sh.

Without explicit definition, the variable is empty when
TARGET_NO_KERNEL was set. Define it to ensure boot.img
is created for the target-files packaging step.

The kernel repo only has the Orange Pi 5 Ultra DTB. Remove
references to other OPI5 variant DTBs. Fix ramdisk dependency
to use built ramdisk.img directly.

TARGET_NO_KERNEL prevented INSTALLED_BOOTIMAGE_TARGET from
being defined, breaking the target-files packaging step.
Use BOARD_KERNEL_IMAGE_NAME instead to satisfy kernel.mk.

Stock AOSP mesa3d doesn't build libgbm_mesa, so the
minigbm_gbm_mesa gralloc wrapper can't link. Remove
for now to get a booting PoC with software rendering.

Stock AOSP mesa3d doesn't build libEGL_mesa, libgallium_dri,
or com.android.hardware.vulkan.panfrost. Remove these references
until Panfrost support is added back.

The kernel is prebuilt and boot image is assembled by mkbootimg.mk
which directly copies Image from the kernel path. Bypass LineageOS
kernel.mk with TARGET_NO_KERNEL since we handle it entirely via
BOARD_CUSTOM_BOOTIMG.
Set BOARD_KERNEL_IMAGE_NAME and TARGET_PREBUILT_KERNEL
for the prebuilt mainline 6.15 kernel Image.
