Dear "Premi, Sanjeev",
In message B85A65D85D7EB246BE421B3FB0FBB59301CC6FBE61@dbde02.ent.ti.com you wrote:
maybe you could explain us why you need it?
[sp] Only as an exercise to see if compiling for ARM v7 provides any better performance - speed and/or power-consumption.
...both of which are most probably irrelevant in a boot loader, thatunder normal operating conditions has a total execution time of just a few hundred milliseconds per power-cycle.
[sp] No, it was not for measuring u-boot but for a small application that I wanted to compare for power consumption. It is probably easier to play with caches, MMU, etc. in the u-boot than in Linux kernel.
Application is merely a calculate-wait-calculate kind of loop.
