Re: [U-Boot] [PATCH] mmc: bcm2835_sdhci: Restore original delay behavior

The get_timer() operates in mSec units instead of uSec though, which caused very slow operation of the driver. Restore the original behavior of the driver, but avoid get_timer_us() and use timer_get_us() instead. The later is part of the standard API.

Marek, This patch causes saveenv to got from almost no time to nearly 50s on my RPi model A+. Can you take a look at that please? Can you try the attached diff ? ;-/ I think I mistakenly used get_timer(), which returns msecs instead of timer_get_us() which reports usecs, sorry. I can confirm this solves the regression. That's not a regression, that was a bug ;-) Ach OK, I thought Stephen said that MMC used to be fast before the offending patch ;) Anyway I don't really know what's the difference and wikipedia says regression is a bug too so we may both be right :P ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Thank you for this information. Is there a way to change a loaded devicetree configuration ? Because we have many boards with small differents. but less memory on disk. at this time one DTB file need ~150kb. we have 1MB free, but we have 20 different boards and every month 1 or 2 new boards. Ugh, nothing comes to my mind, but as I said, I'm a newbie. Maybe someone else can chime in. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
