* | AT91: Small fix on AT91 USART initialization codeXu, Hong2012-09-01-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Before reset dbgu transmitter, we just wait TXEMPTY to drain the transmitter register(Just in case). If not doing this, we may sometimes see several weird characters from DBGU. A short delay is also added to make sure the new serial settings are settled.

* Enable high speed support for USB device framework and usbttyVipin KUMAR2012-03-28-1/+53
| | | | | | | | | | | | | This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed. This function prototype is "int is_usbd_high_speed(void)" Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>

* USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini2011-12-16-4/+6
| | | | | | | | | | | | | | | | | | | | | | In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase where the previous behavior of leaving wMaxPacketSize be unaligned caused fatal problems. The initial fix for this problem was incomplete however as it showed another cases of non-aligned access that previously worked implicitly. This switches to making sure that all access of wMaxPacketSize are done via (get|put)_unaligned. In order to maintain a level of readability to the code in some cases we now use a variable for the value of wMaxPacketSize and in others, a macro.

* Move timestamp and version files into 'generated' subdirSimon Glass2011-10-17-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a rather subtle build problem where the build time stamp is not updated for out-of-tree builds if there exists an in-tree build which has a valid timestamp file. So if you do an in-tree build, then an out-of-tree build your timestamp will not change. The correct timestamp_autogenerated.h lives in the object tree, but it is not always found there. The source still lives in the source tree and when compiling version.h, it includes timestamp_autogenerated.h. Since the current directory is always searched first, this will come from the source tree rather than the object tree if it exists there. This affects dependency generation also, which means that common/cmd_version.o will not even be rebuilt if you have ever done an in-tree build. A similar problem exists with the version file. This change moves both files into the 'generated' subdir, which is already used for asm-offsets.h. Then timestamp.h and version.h are updated to include the files from there. There are other places where these generated files are included, but I cannot see why these don't just use the timestamp.h and version.h headers. So this change also tidies that up. I have tested this with in- and out-of-tree builds, but not SPL. I have looked at various other options for fixing this, including sed on the dep files, -I- and -include flags to gcc, but I don't think they can be made to work. Comments welcome.

| | | | | | | | | | | | | | | | | | | The multi serial support has a "ctlr" field which almost no one uses, but everyone is forced to set to useless strings. So punt it.
