Dear Simon,

Compressed images should have their compression property set to "none" if U-Boot should leave them compressed.
This is especially the case for compressed ramdisks that should be uncompressed by the kernel only.
Is this not self-explaining as is? When you use "none", U-boot wil do nothing to the data - it passes it on unchanged as binay blob.
I donrt see the need for this additional explanation of what seems obvious to me.
Ah, but it's not spelled out. And also given that currently we don't decompress say a ramdisk that spells out compression = "gzip" (is that a regression from initial FIT behavior?) it helps to be clear that putting none here for "don't touch the data" is valid and that the compression property isn't just a descriptive one, U-Boot may decompress the data.
