SD Card Partition Layout for U-Boot, Linux

What is the correct partition layout for writing a bootable SD card with U-Boot and Linux?

The wikis continuously link to Google Drive and nothing can be downloaded from it since the download limits on all the files have been exceeded. I don't really care about using weird Windows utilities anyway, but some example of the layout would be nice to have since I'm using Linux to create my image and can go from there.

My account was limited and now I can't do anything else.

When creating a bootable SD card with U-Boot and Linux, the recommended partition layout usually consists of two partitions. The first partition should be a small FAT32 partition (about 100-200 MB) where U-Boot and bootloader related files, such as u-boot.img, boot.scr, and device tree files, are stored. This partition is marked as bootable. The second partition is the ext4 partition which contains the root file system, which contains the Linux kernel, system libraries and user space applications. This layout ensures that U-Boot can load the kernel and transfer control to the kernel during the boot process.
