I expect a serious boot loader to work in all possible situations and to be a development tool, the thing that was called a monitor ages ago (why do you have "mw" and "md" otherwise?). I've always loved u-boot usefulness as opposed to the crappy "do nothing at all" wince or freecale boot loaders. Thus, I see three reasons to revert the older behaviour. - even if flash got broken over time, the machine should be useable. hang() here gains nothing, as I may still be able to boot though the net and see what happens, without the need to recompile and reflesh a special recovery boot loader - during initial development it's common to have some parameter misconfigured (and thus see no flash) while still using u-boot to md/mw/whatever and see how's flash really mapepd. It makes no sense to be being forced to flash twice at each development loop (one trying new code and hang() and another to get an interactive session). - there may be board build both with and without NOR flash. On one side you added relocation to support boards with different memory sizes with a single u-boot binary, on the other you are now forbidding a single binary to work on two similar boards with a different set of peripherals. This is policy to me, and I see no reason to force policy in a boot loader. I expect only simple and uniform behaviour: do we hang() if no network is found? > If there are problems with the Qemu emulation of NOR flash these > should be fixed there. Sure, if you want flash. I'm not asking non-compliant code the be added in u-boot to deal with a flaky implementation elsewhere. I'd love a perfectly working, though incomplete, emulation to be supported just like real hardware prototypes with production bugs in the NOR mounting.
