Dear Paul Hsu,

On which tool chain is this causing problems?
I use toolchain released by code sourcery(Sourcery G++ Lite 2010q1-202 for ARM GNU/Linux).
Thanks for the information.
And how does this problem manifest?
You did not answer this question. Do you bet build errors? Or does the build complete, but U-Boot does not work correctly?
Build process is complete, but U-Boot does not work correctly. Because of linking the wrong version libgcc.a, which contains armv5 instruction such that arm core raises a undefined instruction exception then code hanged.
NAK. If really needed, this needs to be fixed in ARM specific config files / Makefiles, not in the top level Makefile.
I agree that we should find a better place to put ARM specific config in. But currently, top level Makefile is the one I found. Any suggestion?
arch/arm/config.mk ?
I found another way to solve this issue.
In arch/arm/cpu/arm920t/config.mk, change this line from PLATFORM_CPPFLAGS += -march=armv4 to PLATFORM_CPPFLAGS += -march=armv4t
Then everything goes well. This solution won't make any modification on top level Makefile.
But I don't know exactly that the solution will incur other side effect or not?
BTW, If this solution is the right thing to do, shall I issue another patch?
BR, Paul
