2014-12-29initcall: add explicit hint if initcall was relocatedAlexey Brodkin
Commit "initcall: Improve debugging support" makes sense and indeed simplifies process of matching initcalls executed with static disassembly. Until you are debugging relocation functionality. Existign output may make you think that at some point execution somehow returned back to non-relocated area. And there're many reasons/problems that may provoke this behavior. In order to make things clear let's add explicit mention in case initall was actually relocated like this: --->--- initcall: 810015f8 Relocation Offset is: 0efcf000 Relocating to 8ffcf000, new gd at 8fdced3c, sp at 8fdced20 initcall: 810015b8 initcall: 8ffd093c initcall: 8ffd0a14 initcall: 81001940 (relocated to 8ffd0940) initcall: 81001958 (relocated to 8ffd0958) --->--- Note "unexpected" jump from 0x8f... area to 0x81... area. Without explanation this raises many questions: execution jumped in relocated area right as expected and then for some reason returned back? But I hope comment in brackets will save some time for those curious developers who are careful enough to catch "unexpected jump to pre-reloc area" or those unlucky ones who'll have to deal with relocation debugging.

2014-10-22initcall: Display error number when an error occursSimon Glass
Now that some initcall functions return a useful error number, display it when something goes wrong. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
2014-05-28initcall: Improve debugging supportSimon Glass
Add the ability to display the code offset of an initcall even after it is relocated. This makes it much easier to relate initcalls back to the U-Boot System.map file. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

2013-03-15Introduce a basic initcall implementationSimon Glass
This library supports calling a list of functions one after the other. It is intended that we move to a more powerful initcall implementation as proposed by Graeme Russ <graeme.russ@gmail.com>. For now, this allows us to do the basics. Signed-off-by: Simon Glass <sjg@chromium.org>
