OMAP3 support recently merged is version from mid december 2008.
This patch series adds some additional clean up, fixes and
improvements done since then. It brings U-Boot mainline in sync
with U-Boot tree of OMAP3 developers ("omap3-dev").
This patch series is against U-Boot mainline, commit
6c6e042ab3bbfb5428e4cdeb38fa27728c63afdd "Merge branch 'master'
of git://git.denx.de/u-boot-arm"
Best regards
Dirk

But my understanding and implementation goal is to have MUSB clock enabled only if CONFIG_MUSB is enabled (and not every time). As mentioned above, this will be done later with an USB patch to be sent to USB maintainer. I.e. MUSB clock will be enabled only if it is really needed because CONFIG_MUSB is enabled (by patch to be sent later). Dirk ^ permalink raw reply [flat|nested] 26+ messages in thread

Hmmh. With OMAP3 SoC we have a (serial) number we can easily access and report independent of board similar on all OMAP3 based boards. Yes, you are right, this is no board serial number. But as OMAP3 is something like 515-pin PBGA with .4mm/.65mm pitch, board and cpu (SoC) will most probably never be split/exchanged by 'normal' user. I really hope that for OMAP3 you can accept that we report OMAP3 serial number and not (maybe even not existing) board serial number?

Well, this is a very good example of why it is good to "use macros instead of hard coded values" :) Looking at the changes done in this patch, thanks to the macros used, it is obvious that here pulls are enabled for MMC data/cmd lines, and disabled for clock line. In case you are familiar with MMC hardware configuration, you should know why this is necessary. Dirk ^ permalink raw reply [flat|nested] 26+ messages in thread

Note that we follow here (and in the serial number patch) the concept of "touch hardware only once, remember the value and then deal with the remembered value. Don't touch hardware again if done already". I.e. it's the concept behind this to not have a function to read HW (and do masking etc) again and again if revision value is needed.

But no, we don't want to split ~20 changed lines into even smaller parts to a) avoid spamming the list b) avoid polluting the git history > because it's not so easy to folow which modification fix what?
