Hi, Here is a patch (will be sent as a reply to this mail) for review that will add a sparc-leon uart driver to the kernel. It includes the amba plug and play (ambapp) core bus routines drivers/ambapp/ambapp.c and drivers/ambapp/ambapp_driver.c as well as the first driver drivers/ambapp/gaisler/apbuart/apbuart.c. There are some more drivers (ethernet and gpio) that I'll post after this one has been accepted. drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/ambapp/Kconfig | 9 + drivers/ambapp/Makefile | 6 + drivers/ambapp/ambapp.c | 361 +++++++++++++ drivers/ambapp/ambapp.h | 246 +++++++++ drivers/ambapp/ambapp_driver.c | 219 ++++++++ drivers/ambapp/gaisler/Kconfig | 20 + drivers/ambapp/gaisler/Makefile | 3 + drivers/ambapp/gaisler/apbuart/Makefile | 3 + drivers/ambapp/gaisler/apbuart/apbuart.c | 837 ++++++++++++++++++++++++++++++ include/linux/serial_core.h | 3 + It also includes the _amba_init() routine that is called from within sparc at bootup and that will dynamically build the device tree. Having the Sparc-leon architectural part and the uart driver one can build a simple system for leon already (bootloader and user apps on top)... I'm not shure wher to add the drivers/ambapp/Kconfig, I just added it to drivers/Kconfig however maybe arch/sparc/Kconfig might be more approprite. -- Greetings Konrad -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
