[U-Boot] [U-boot] Export functions using Jumptable in Standalone application
Hi,
In one of my standalone application used for initializing the hardware(Ethernet Switch) registers, I have exported two functions miiphy_read() and miiphy_write() of u-boot as per the procedure given in README.standalone document. By doing so, will my standalone application come under GPL? If yes, is there any other way to implement this?

Is this initialization necessary for the network operation in U-Boot?

Hi,
Yes we require this initialization of the switch for network operation.

If the initialization is needed to run Ethernet, and if you ant to use network functions in U-Boot, then you should link the code to initialize the Ethernet hardware with the U-Boot image.

Hi,
Thanks for your responses Wolfgang! - I think in that case if I link the initialization code with the u-boot image, then my standalone application will come under GPL conditions, right? If I dont do any network operations in U-boot(dont link the code with u-boot image), just do the hardware initialization of the switch registers only, then will my standalone application have any sort of issues with respect to the GPL?

Yes, of course.

If you do not want to use the network interface then there is no reason to initialize the switch in U-Boot. Design rules say that only such devices shall be initialized that are used by U-Boot itself, see bullet 2 at http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast
I am not a lawyer, but my general feeling is that you should accept the fact that U-Boot is under GPL.
