For 32-bit ARM, - * it must be within the first 128M of RAM in order for the kernel's - * CONFIG_AUTO_ZRELADDR option to work. The kernel itself will be decompressed - * to 0x8000 but the decompressor clobbers 0x4000-0x8000 as well. The - * decompressor also likes to relocate itself to right past the end of the - * decompressed kernel, so in total the sum of the compressed and and - * decompressed kernel needs to be reserved. - * - * For Aarch64, the kernel image is uncompressed and must be loaded at - * text_offset bytes (specified in the header of the Image) into a 2MB - * boundary. The 'booti' command relocates the image if necessary. Linux uses - * a default text_offset of 0x80000. In summary, loading at 0x80000 - * satisfies all these constraints and reserving memory up to 0x02400000 - * permits fairly large (roughly 36M) kernels. - * - * scriptaddr and pxefile_addr_r can be pretty much anywhere that doesn't - * conflict with something else.

In practice, this usually means not - * more than ~700M away from the start of the kernel image but this number can - * be larger OR smaller depending on e.g. the 'vmalloc=xxxM' command line - * parameter given to the kernel. So reserving memory from low to high - * satisfies this constraint again.
