In my experience, I tend to search for board names first.
So back to the root of my question, do we just have one really long list of board names?
I'm not an expert for the capabilities of Kconfig, but one looong list with hundrets of entries clearly makes no sense. We obviously need sum grouping / structuring.
IMHO there should be several options:
- for those who look for a board name, we should support this,
probably wih an initial selection by the first letter (case insensitive) of the board name.
like this: => board name => M => MPC837XERDB
- alternatively, it should be possible to restrict the choice by
selecting first processor architecture (ARM, PowerPC, MIPS, ...), then CPU (family) name, then board names.
like this: => Architecture => PPC => MPC83xx => MPC837XERDB
Sam,
We are looking at moving u-boot to use Kconfig and was wondering if you could possible tell us if its possible to represent the same Kconfig 'config' options via two different menu schemes. We have a list of boards that will be 'config' options. We'd like to have it in one 'menu' that is just a long list of boards. The other would be a smaller subset that you "filter" based on selecting an Arch & Subarch.
Kconfig does not allow you to duplicate a config entry in two menus in a way that is usefull here. You want to use the same name, prompt and help text in both menus.
I think the solution is to have a filter part and a "list all boards" part. Then the filter part can be used to make the board list smaller.
Below is a quick mock-up of the idea. I used CPU + INTERFACE - reading the above I should have used Arch + SubArch but you get the idea.
If you decide to do something like this then hide most of this in a separate file and include it.

is something like this possible?
