2012-10-15serial: pxa: Move serial registration from serial_initialize()Marek Vasut1-0/+13
Move the registration of serial_XXuart ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented pxa_serial_initialize() function, which is implemented inside of the serial_pxa driver allows encapsulation of serial_XXuart within the serial_pxa driver itself. Also, remove the exports of serial_XXuart from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the serial_pxa driver and the default console is picked by CONFIG_CONS_IDX macro in config file.

2012-10-15serial: Rename .init() and .uninit() in serial_deviceMarek Vasut1-2/+2
Rename .init() to .start() and .uninit() to .stop() in struct serial_device. This allows aligning struct serial_device with closer to struct stdio_dev. The real goal here is to allow these two structures to converge together and eventually make one to be a superset of the other.

2012-03-28Enable high speed support for USB device framework and usbttyVipin KUMAR2-1/+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.

2011-12-16USB: Use (get|put)_unaligned for accessing wMaxPacketSizeTom Rini1-4/+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.

2011-10-17Move timestamp and version files into 'generated' subdirSimon Glass1-1/+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.
