2014-03-10usb: create common header virtual root hub descriptorsStephen Warren
Many USB host controller drivers contain almost identical copies of the same virtual root hub descriptors. Put these into a common file to avoid duplication. Note that there were some very minor differences between the descriptors in the various files, such as: - USB 1.0 vs. USB 1.1 - Manufacturer/Device ID - Max packet size - String content I assume these aren't relevant.

2014-03-07powerpc/usb: Workaround for erratum-A006261Suresh Gupta
USB spec says that the minimum disconnect threshold should be over 525 mV. However, internal USB PHY threshold value is below this specified value. Due to this some devices disconnect at run-time. Hence, phy settings are tweaked to increased disconnect threshold to be above 525mV by using this workaround.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

Single-source clocking is new feature introduced in T1040. In this mode, a single differential clock is supplied to the DIFF_SYSCLK_P/N inputs to the processor, which in turn is used to supply clocks to the sysclock, ddrclock and usbclock. So, both ddrclock and syclock are driven by same differential sysclock in single-source clocking mode whereas in normal clocking mode, generally separate DDRCLK and SYSCLK pins provides reference clock for sysclock and ddrclock DDR_REFCLK_SEL rcw bit is used to determine DDR clock source -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in normal clocking mode by DDR_Reference clock -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in single source clocking mode by DIFF_SYSCLK Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

On PCI v2.4 use the old base = 256 and, on PCI 3.0 where some of the PCIE liodns are larger than 256, use a base = 1024. The version check is based on the PCI controller's version register.
