Just a bit more. Is there any reference which provides the functionalities supported by uboot of size 80KB?
No, but you can easily try it out - chose a board (probably one without embedded environment) and de-select features; build and test.
Performance option was wrong. It doesn't mean anything to the bootloader.
Well, of course the boot loader should not add unnecessary delays to the total boot time.
To do some justice to u-boot, performance is actually an issue in some areas. For example, on a device with slow flash but fairly fast CPU, being able to compress your OS image then decompress before booting it is quite a performance advantage. In our tests, a gzipped uImage begins booting the OS about 2-5 seconds faster than an unzipped image, depending on how big the kernel is.
