Re: wl1251 build woes (compat-wireless 3.3.1-1, 3.1.1 as well as 2.6.39)

I've had somewhat limited success with this - I was able to build 2.6.38-2 compat-wireless by manually copying "db.txt" as well as "genregdb.awk" to <android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless (yeah, I created it manually) as well as forcing CONFIG_CRC7=y and CONFIG_WL12XX_PLATFORM_DATA=y.I initially used compat-wireless-3.3.1-1 as it was the latest "stable" kernel edition released. The wl1251 drivers are in net/wireless/wl1251, not drivers/net/wireless/ti/wl1251. That is also the case with the latest released compat-wireless - 3.4-rc3-1.If this is a recent compat-wireless, then the wl1251 driver was moved to drivers/net/wireless/ti/wl1251. Can you check that?I did a bit of hacking/tweaking, but ran into much bigger problems and simply gave up in the end. When I looked at various compat-wireless makefiles I saw that, somehow the inclusion of wl1251 as well as wl12xx depends on CONFIG_CRC7 and CONFIG_WL12XX_PLATFORM_DATA being set (the latter also depends on wl12xx, so if I wanted it included, I had to switch to "wl12xx" instead of "wl1251"). So, I did the following:./scripts/driver-select restore ./scripts/driver-select wl12xxmake ARCH=arm CROSS_COMPILE=$CCOMPILER KLIB=<android_kernel_dir> KLIB_BUILD=<android_kernel_dir> CONFIG_CRC7=y CONFIG_WL12XX_PLATFORM_DATA=yI then get the following errors:/builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.c: In function 'wl12xx_sdio_power_on': /builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.c:126:2: error: implicit declaration of function 'pm_runtime_enabled' [-Werror=implicit-function-declaration] /builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.c:132:7: error: void value not ignored as it ought to be /builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.c: In function 'wl12xx_sdio_power_off': /builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.c:153:6: error: void value not ignored as it ought to becc1: some warnings being treated as errorsmake: *** [/builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx/sdio.o] Error 1 make: *** [/builddir/compat-wireless-3.3-1/drivers/net/wireless/wl12xx] Error 2 make: *** [/builddir/compat-wireless-3.3-1/drivers/net/wireless] Error 2make: *** [_module_/builddir/compat-wireless-3.3-1] Error 2 make: Leaving directory `<android_kernel_dir>' make: *** [modules] Error 2Apparently, "pm_runtime_enabled" is defined in include/linux/pm_runtime.h, but this is for the 3.0+ version of the kernel - I am using 2.6.37! Something seems to be seriously screwed up! The above is valid for all 3.x versions of compat-wireless I tried! I was under the impression that compat-wireless is backward-compatible with "older" kernel versions, like mine, is that not the case?!When I tried the latest compat-wireless before 3.x (2.6.39-1) I don't get the first error, but get the other two, albeit with modified function names (wl1271_sdio_* instead of wl12xx_sdio_*).In addition to the above, for some reason when I run compat-wireless for versions prior to 3.x (I tried 2 such versions - 2.6.39-1 and 2.6.38-2) I also get a weird error that "<android_kernel_dir>//builddir/compat-wireless-XXX/net/wireless/db.txt cannot be found" - the search path there is completely wrong, it should either be <android_kernel_dir>" or "/builddir/compat-wireless-XXX/net/wireless/db.txt" and not this weird concatenated path containing both!Again, this only happens with the 2 releases prior to 3.x I tried and only when I have "db.txt" and "genregdb.awk" from 3.3.1-1 manually copied to net/wireless. Any help?
"make modules-install" gives me 6 modules: compat, cfg80211, mac80211, wl1251, wl12xx_platform_data and wl1251_sdio. I "modprobe" them in that order, but then I get this error:

As evident from the above also, the firmware does not load either. Here is what I have:

I did a bit of investigation and it turns out that the offending part of the code is in the select-driver script, which executes "egrep WL1251|WL12XX" on the original Makefile and since the Makefile CONFIG_* setting does not contain either of these values for the ti/ directory (it has something like CONFIG_TI_*) that results in an empty Makefile.
Even if I correct this and leave just the ti-related settings in that Makefile, I am still faced with my original problem I already pointed out above - wl1251, wl1251_sdio and wl12xx are not built - just compat, mac80211 and cfg80211 are compiled, so I am stuck - good and proper, again.
