PATCH v2 1/4 arm64: Correct passing of Linux kernel args

The Documentation/arm64/booting.txt document says that pass in x1/x2/x3 as 0 as they are reserved for future use.

PATCH v2 2/4 cmd_bootm.c: Add 'booti' for ARM64 Linux kernel Images

In reply to Tom Rini

The default format for arm64 Linux kernels is the "Image" format, described in Documentation/arm64/booting.txt. This, along with an optional gzip compression on top is all that is generated by default. The Image format has a magic number within the header for verification, a text_offset where the Image must be run from, an image_size that includes the BSS and reserved fields.

This does not support automatic detection of a gzip compressed image.

This should work for a defconfig, but it might be possible to build a larger kernel. From experiments with an allyesconfig, I can build a ~60MB kernel with ~20MB of uninitialised data after the end of the Image.

Modifying the Image feels a little dodgy, but I can't think of anything this would break.

This should be le64_to_cpu(ih->text_offset) to be strictly correct.

Part of me just wants to error out in this case. Today people are wrapping vmlinux up with a legacy header and making uImages. My hope is that with this and 3.17 we can encourage Image/Image.*/FIT Image usage instead. We could just as easily whack in 128MB, all the same.

Yeah. In my mind, an Image without this information is the corner case, not the normal case. Doing it this way (a fixup to the data) means we don't have to error check this twice or play some other games.

Sure, it's unlikely that someone will build that big a (< v3.17) kernel for reasons other than breaking things. I just thought I should mention in case this crops up again.

Ok. As I said I can't think of anything this should break. This should only affect older kernels so shouldn't be a problem going forward.

Prior to v3.17 you'll also find the text_offset field could be in an arbitrary endianness, though should always have value 0x80000. So if you want to boot BE (< v3.17) kernels you'd have to fix that up too. Post v3.17 it's subject to randomization.

Cheers,
Mark.
