Hello everyone,

Thanks to Sigrid, I have found the struct legacy_img_hdr on 
https://github.com/u-boot/u-boot/blob/master/include/image.h, which 
helps a lot in understanding /sys/src/cmd/aux/txt2uimage.c/, but I still 
have a few questions:

If there is a "legacy" struct, is there possibly a newer struct that 
could also be used?

The "Image Magic Number" in /sys/src/cmd/aux/txt2uimage.c/ is the same 
es the one defined in include/image.h, but what is its function? (And 
why is it that number?)

Why are 8 bit added to the Image Data Size? (header[12])

Why is IH_OS_INVALID (0) used instead of IH_OS_PLAN9 (23)? (header[28])

Why is IH_ARCH_INVALID (0) used instead of IH_ARCH_ARM64 (22)? 
(header[29])

Thank you very much in advance!
