Re: [U-Boot] [PATCH 0/2] omap3: Optimize detection of cpu revision

Dear Sanjeev,

in message B85A65D85D7EB246BE421B3FB0FBB59301E1EB4A5D@dbde02.ent.ti.com you wrote:

Also, I believe faster execution time is always better; not just in critical sections of code. I possibly used "global" quite loosely; while responding earlier. The variable cpu_revision (being discussed) here is actually a 'static'. (See patch 1/2).

So how much faster is reading this variable compared to reading from the register?

Can you really measure _any_ difference?

But, if we feel otherwise, I can revert to executing detection mechanism each time in the function.

Please undo this.

Best regards,

Wolfgang Denk
