Re: [U-Boot] [PATCH] LZO: Add a LZO compression feature

Dear Donggeun Kim,

In message 4CA5B732.3030706@samsung.com you wrote:

In some case, LZO compression function is needed in U-Boot.

Can you please explain what use cases you have in mind?

So far, we provide only uncompression functions, and it seems nobody ever needed compression inside U-Boot yet?

If we really add this, then please make it separately configurable, so that not everybody who wants LZO decompression always has to accept the compression functions, too.

This patch supports LZO compression feature which is originated from Linux kernel.
