Re: [U-Boot] [PATCH] tools: mkimage can read input on /dev/stdin

Dear Julien,

I don't believe you. Sizes rare certainly not identical, and neither is the performance. Did you do any real measurements?

mmap is useful when you need to make random access in a file, or to optimize memory: when a file is mmapped, the kernel only loads the parts of the file that are accessed. In the case of mkimage, the file is read sequentially (meaning all of it will be retrieved from the disk).

OK, so you don't have any real data, but make a very specific statement: "exactly the same."

Sorry, but this is not an answer I'm going to buy.

Best regards,

Wolfgang Denk
