* kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada2014-09-16-1/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

* musb-new: am35x backend driverIlya Yanok2012-11-20-0/+709
Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
