2017-07-30x86: theadorable-x86-dfi-bt700: Add Spansion SPI support and move VIDEO blobStefan Roese
To support the Spansion SPI NOR flashes, this patch enables the support in defconfig. This increases the U-Boot binary too much so that it does not fit into its area in the ROM. So also move the VIDEO BIOS blob a bit to make some space here. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Add Intel Edison board which is using U-Boot. The patch is based on work done by the following people (in alphabetical order): Aiden Park <aiden.park@intel.com> Dukjoon Jeon <dukjoon.jeon@intel.com> eric.park <eric.park@intel.com> Fabien Chereau <fabien.chereau@intel.com> Felipe Balbi <felipe.balbi@linux.intel.com> Scott D Phillips <scott.d.phillips@intel.com> Sebastien Colleur <sebastienx.colleur@intel.com> Steve Sakoman <steve.sakoman@intel.com> Vincent Tinelli <vincent.tinelli@intel.com> In case we're building for Intel Edison, we must have 4096 bytes of zeroes in the beginning on u-boot.bin. This is done in board/intel/edison/config.mk. First run sets hardware_id environment variable which is read from System Controller Unit (SCU). Serial number (serial# environment variable) is generated based on eMMC CID. MAC address on USB network interface is unique to the board but kept the same all over the time. Set mac address from U-Boot using following scheme: OUI = 02:00:86 next 3 bytes of MAC address set from eMMC serial number This allows to have a unique mac address across reboot and flashing.

So far LS/FS devices directly attached to xHC root port can be successfully enumerated by xHCI driver, but if they are connected behind a hub, the enumeration process fails to address the device. It turns out xHCI driver still misses a part that in the device's input slot context, all Transaction Translator (TT) related fields are not programmed. The xHCI spec defines how to enable TT. Now LS/FS devices like USB keyboard/mouse can be enumerated behind a high speed hub. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

A high speed hub has a special responsibility to handle full speed/ low speed devices connected on downstream ports.

2017-07-28usb: xhci: Program 'route string' in the input slot contextBin Meng
xHCI spec says: the values of the 'route string' field shall be initialized by the first 'Address Device' command issued to a device slot, and shall not be modified by any other command. So far U-Boot does not program this field, and it does not prevent SS device directly attached to root port, or HS device behind an HS hub, from working, due to the fact that 'route string' is used by the xHC to target SS packets. But in order to enumerate devices behind an SS hub, this field must be programmed. With this commit and along with previous commits, now SS & HS devices attached to a USB 3.0 hub can be enumerated by U-Boot. As usual, this new feature is only available when DM is on.

2017-07-28x86: minnowmax: Add a environment variable for USB power-on delayBin Meng
Occasionally it was observed that on Intel MinnowMax board, with a USB 2.0 device connected to the bottom port, when doing 'usb start' on the xHCI controller: scanning bus 0 for devices... cannot reset port 3!? But neither of the two USB ports is routed to xHCI root port 3. Adding some debug information shows that xHCI port 3 PORTSC register mysteriously reports both CCS = 1 and CSC = 1. This is not seen every time. After increasing the timeout to wait for power to become stable, the issue is gone. So this indicates current default USB power-on delay (20ms) might be at a critical region where power is stable/unstable. U-Boot provides a mechanism to have a environment variable to override the default one. Add one for MinnowMax.
