This commit adds test script for testing if any commit has introduced regression to the DFU.
It uses md5 to test if sent and received file is correct. The test detailed description is available at DESCRIPTION.TXT file.

This sounds like an important and useful test, but I have a few comments (coming from someone with little knowledge of dfu)
Would README be a better name?

+For running test script one needs to create: +./log and ./bkp
+One also need to generate with dd following files:
+dat_*
+(e.g. dat_127B.img dat_128B.img dat_129B.img dat_33M.img dat_4095B.img +dat_4096B.img dat_4097B.img dat_63B.img dat_64B.img dat_65B.img +dat_960.img dat_97M.img)
How do you do that? Is this intended for use with a particular board? I think you are missing some info here.
+The size is only important (so if=/dev/urandom), especially corner cases of +DFU EP0's size of packet (64B). This is very helpful for fixing UDC driver +regressions.
+Moreover on a target device the "dfu_alt_info" env variable should be extended +to have "dfu_test.bin fat 0 6;" \ entry [1].
What is [1] ?
+One can use fat, ext4 or any other supported file system.
+As a prerequisite one must also create proper partition with file system on it.
+Example usage: +./dfu_gadget_test.sh 11
+where 11 is the mumber of alt setting corresponding to entry [1]. \ No newline at end of file
I'm really none-the-wiser as to how this works - I think you need to add a bit more detail.

Perhaps define $RED or whatever at the top and use those here?

I suggest putting the argument in a variable here, instead of using $1 throughout the function.

Why not?
