Bug Description

Bluetooth does not work on build https://android-build.linaro.org/builds/~linaro-android/leb-panda/#build=228 but it works when you replace MLO and u-boot from http://releases.linaro.org/platform/linaro-n/android/11.08/leb-panda/boot.tar.bz2 . uim service fails to communicate on ttyO1 .
Looks like there is some uart1 initialization issue at bootloader level in MLO/u-boot.img which are getting being built in latest code.

Which u-boot version/hash were you using previously? Would be good to know if it was already based on u-boot-linaro or if it was still the old one supported by TI.

Just to know if this is related with SPL support or when using u-boot-linaro in general.

The case where it works,It doesnt use spl.
It worked when u-boot.bin from
http://git.linaro.org/gitweb?p=boot/u-boot-linaro-stable.git;a=shortlog;h=9a1d882b96a119fe3fffd2be294e82e99b732a06 and an MLO image which is a prebuilt image from this commit
http://android.git.linaro.org/gitweb?p=device/linaro/pandaboard.git;a=commit;h=97312013c5f002ac8250446cd89077f84a837e7d

The latest build uses spl and u-boot from the commit
http://git.linaro.org/gitweb?p=boot/u-boot-linaro-stable.git;a=shortlog;h=01915ec14ee46a4ddfc1f6ea996096e92ff7e802

This looks to be something to do with the SPL support.

Can you try using the one from hash
http://git.linaro.org/gitweb?p=boot/u-boot-linaro-stable.git;a=commit;h=6cdc90c5e6bad76b6f7e616315535d8899897529
?

After the hash you're using there's another commit that updates the
mux settings, and I believe some are related with BT support.
