Re: [U-Boot] [PATCH v1 (WIP) 09/16] [Timer]Replace get_timer() usage in drivers/block/

Dear All,

Well I know i have asked this before, but I feel I should ask again because I didn't like the answer much.

Imagine we change this code to:

ts = time_now_ms() + msec do { ... } while (time_since_ms(ts)< 0);

That should be legal, right? But I don't think this can work since the 'since' functions return an unsigned.

[aside: this provides for another idiom that I think we talked about:

ts = time_future_ms(msec) do { ... } while (!time_passed(ts))

which I am not at all suggesting should be in the API :-) end aside]

I still vouch for this concept, which is simple, clean, and easy to understand.
