2017-10-02Provide a generic io.h & address mapping functionsPaul Burton
Most architectures currently supported by U-Boot use trivial implementations of map_to_physmem & virt_to_phys which simply cast a physical address to a pointer for use a virtual address & vice-versa. This results in a lot of duplicate implementations of these mapping functions. The set of functions provided by different architectures also differs, with some having implementations of phys_to_virt & others not. A later patch will make use of phys_to_virt in architecture-neutral code, and so requires that it be provided for all architectures. This patch introduces an asm-generic/io.h which provides generic implementations of address mapping functions, allowing the duplication of them between architectures to be removed. Once architectures are converted to make use of this generic header it will also ensure that all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are provided. The 2 families of functions differ in that map_physmem may create dynamic mappings whilst phys_to_virt may not & therefore is more limited in scope but doesn't require information such as a length & flags. This patch doesn't convert any architectures to make use of this generic header - later patches in the series will do so.

Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco. This macro can be used as follows: #define TEST(x) CALL_MACRO_FOR_EACH(TEST, a, b, c, d) This will expand to TEST(a) TEST(b) TEST(c) TEST(d) The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the number of arguments can vary (although it has an upper limit - in this implementation 32 arguments).

2017-10-01usb: xhci: Honor endpoint's intervalBin Meng
USB endpoint reports the period between consecutive requests to send or receive data as bInverval in its endpoint descriptor. So far this is ignored by xHCI driver and the 'Interval' field in xHC's endpoint context is always programmed to zero which means 1ms for low speed or full speed , or 125us for high speed or super speed. We should honor the interval by getting it from endpoint descriptor. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

2017-10-01usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()Bin Meng
Current emulator select logic in usb_emul_find_devnum() is to test the USB address. The USB address of the device being enumerated is initialized to zero at the beginning of the enumeration process in usb_setup_device(). At this point, the saved USB address in the platform data has not been assigned to any valid USB address either. This means: the logic will select an emulator device according to its sequence of declaring order in the device tree. Take test.dts for example, flash-stick@0 will be selected before flash-stick@1. But unfortunately such logic is wrong. In fact USB devices show up in a random order during the enumeration which means usb_emul_find_devnum() may be called on port 3 for keyb@3 before on port 0 for flash-stick@0. To fix this, we introduce a new emulator uclass specific platdata to store the USB device's port number on its parent hub, and update the logic to test the port number instead.
