Re: [U-Boot] [RFC PATCH] arm: provide a CONFIG flag for disabling relocation

Dear Aneesh V,

In message 1301058732-30898-1-git-send-email-aneesh@ti.com you wrote:

Relocation may not be needed and desirable in many cases:

• For many boards the amount of SDRAM is fixed. So relocation is not needed.

This is plain wrong. This has been explained a couple of times before. Please read the archives.

• Relocation adds un-necessary additional overhead when it's not needed. This delay is singificant on slower platforms such as FPGA

Do you have numbers? How much delay do you see caused by the relocation of U-Boot?

• Many boards have ample memory. So reserving enough memory for Linux in the first half is not a challenge even without relocation

You appear not to understand what relocation is needed for.

I tend to reject your patch, unless you can come up with really convincing arguments. Also, your patch should then work for all boards - not only ARM, but also PowerPC (one of the arguments for relocation was that we want to unify the code).

Best regards,

Wolfgang Denk
