Request for U-Boot Support for Allwinner A133 Device

Subject: Request for U-Boot Support for Allwinner A133 Device

Dear U-Boot Maintainers,

I am working on recovering a soft-bricked Android 10 tablet with the
Allwinner A133 SoC. The bootloader is unlocked, and I have backups of key
partitions (super.img, boot.img, vbmeta.img, recovery.img). However, I am
unable to locate a suitable U-Boot configuration or prebuilt binary for
this board.

I have attempted to build U-Boot using the official repository but
encountered difficulties in finding the correct defconfig and board support
for this device. If there are any existing U-Boot configurations, binaries,
or guidance for the Allwinner A133 (or similar boards like the A100), I
would greatly appreciate your help.

Thank you for your time and assistance.

Best regards,
Johnohhh1
