u-boot.lds questions

I've "successfully" built my u-boot port (it doesn't throw warnings/error).

To do so I just copied some u-boot.lds from some other port. I know that the u-boot.lds is a linker script that instructs the linker to put code elements together in some specific way. At least the first part does so. But the lower parts of the u-boot.lds I copied seem to be increasingly deep magic. So... what does the u-boot.lds do exactly and what happens if mine is wrong/broken? And why do I need it anyway?

The built put out the following things in the main directory:

-rwxr-x--- 1234997 Jan 19 12:51 u-boot
-rwxr-x--- 171372 Jan 19 12:51 u-boot.bin
-rw-r----- 94836 Jan 19 12:51 u-boot.map
-rwxr-x--- 514202 Jan 19 12:51 u-boot.srec

there are some parts that probably are important in board/esm (my board's directory) too:

-rw-r----- 17000 Jan 17 16:05 esm.o
-rw-r----- 17176 Jan 17 16:05 libesm.a

Does that look reasonable/good?

I can't put it any better: It is a linker script that instructs the linker to put code elements together in some specific way.

Your code will not run and/or crash.

You need it to get a working image.

This is impossible to say from this information. u-boot.map might be interesting to check - for you; please don't post it here, though.
