ARM march architecture version for arm926ejs in config.mk

Hi,

i have seen questions on the mailing list about march for arm926ejs being mentioned as -march=armv4.

http://www.nabble.com/-PATCH--ARM%3A-Fix-arm-architecture-version-for-ar
m926ejs-td5195486.html#a5210157

http://www.nabble.com/-patch-u-boot-git-2-3--better-ARM9-compiler-option
s-td14962153.html#a15009686

But according to the Wikipedia
(http://en.wikipedia.org/wiki/ARM_architecture ) , architecture version for ARM926EJ-S is ARMv5TEJ.

Kindly can someone explain why this is done. Previously few have provided the patch but all have been rejected or not applied.

Sorry if this is a repeated question.

Thanks in advance.

Correct
Please confirm, off list, that you can access http://infocenter.arm.com/
for your future ARM architecture investigations....

I think the position is that -march=armv4 is compatible with more toolchains and builds code which runs on all later architectures,
whilst the correct architecture setting provides minimal benefits (to U-Boot).

However, I'm still working on my compiler options patch, mainly to satisfy the list comments re -msoft-float.

I hope to have it available for the next merge window.

Meanwhile you can get the current snapshot from www.linux-arm.org/git/u-boot-armdev.git/080212_options.

I'd be interested in your comments.

Peter

I've reject this patch due to warnings on my toolchains

I've plan to investigate on this soon

Best Regards,
