Running the contained script the directory will be populated with all need files (LzmaTypes.h, LzmaDecode.*). Anyway, I can resubmit the patch including all files. The LZMA SDK is released under LGPL with exceptions but I don't understand if the license is compatible with the u-boot's license. For this reason I omitted the sources from the SDK.
This makes no sense to me.
Either the license is compatible, and the code can be included, or it is not, then it cannot. In the latter case, the whole patch makes no sense.
I think there should be no problem from a license point of view.
The home page says that you can use unmodified source in your own code without having to release it to the public.
Since U-boot is open source to start with, this cannot be a problem.
It goes on and says that if the LZMA lib is modified, then the resulting code has to be released as open source. Again, no problem for U-boot, since it is open source to start with.
There are also commercial licenses available, but that is not applicable since noone signed a commerical license.
Please check for compatibility of licenses berfore resubmitting.
LMZA performs better than LZ on binary files. I will switch to LZMA to save flash memory space on my appliance. Of course, the LZMA is slower than LZ.
But so far there is no code (board support) in U-Boot to use this feature, right? And it's not used by the Linux kernel either?
There are kernel patches for LZMA compression available. Can be selected at least in buildroot.
And your patch does not even enable support for it in the mkimage tool, so you cannot even create images that use the feature?
Maybe the patches for Linux creates an image??? Never saw any need to use it myself.
How exactly is this code supposed to be used?
Anyway, if the LZMA SDK license is compatible with U-boot , I think that LZMA should be chosen by firmware developer when the flash memory space is a critical resource.
Frankly, if you are so short with flash you have a h/w design problem.
Lots of applications are cost sensitive, and shaving 50 cents here, 50 cents there could be important. Hard to judge without knowing the details.
