2012-10-15Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren
patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean. Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15tegra20: add USB ULPI init codeLucas Stach
This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

2012-10-15usb: ehci: rework to take advantage of new lowlevel interfaceLucas Stach
Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean. Signed-off-by: Lucas Stach <dev@lynxeye.de> Reviewed-by: Marek Vasut <marex@denx.de>

2012-10-15serial: bfin: Flip the jtag serial console to CONFIG_SERIAL_MULTIMarek Vasut
Rework the emulation of serial console via JTAG from simple ad-hoc implementation of serial port routines to CONFIG_SERIAL_MULTI and enable CONFIG_SERIAL_MULTI unconditionally for blackfin. In order for the JTAG serial console to take precedence over all other serial ports available in system, implement override for default_serial_console call returning this JTAG serial console. This brings in a bit of a growth of size, but eventually will allow us to unconditionally enable CONFIG_SERIAL_MULTI throughout the whole U-Boot and maintain only one serial subsystem.

2012-10-15serial: mpc512x: Move serial registration from serial_initialize()Marek Vasut
Move the registration of serialN_device 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 mpc512x_serial_initialize() function, which is implemented inside of the mpc512x serial driver allows encapsulation of serialN_device within the mpc512x serial driver itself. Also, remove the exports of serialN_device from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the mpx512x serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.
