2015-04-18dm: x86: pci: Convert chromebook_link to use driver model for pciSimon Glass
Move chromebook_link over to driver model for PCI. This involves: - adding a uclass for platform controller hub - removing most of the existing PCI driver - adjusting how CPU init works to use driver model instead - rename the lpc compatible string (it will be removed later) This does not really take advantage of driver model fully, but it does work. Furture work will improve the code structure to remove many of the explicit calls to init the board. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-04-16ti: dwc3: Enable clocks in enable_basic_clocks() in hw_data.cKishon Vijay Abraham I
Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY) changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between the two dwc3 controllers present in dra7xx/am43xx and enabled these clocks in enable_basic_clocks() in hw_data.c. However these clocks continued to be enabled in board files/driver files for dwc3 host mode functionality causing compilation break with few configs. Fixed it here by making all the clocks enabled in enable_basic_clocks() and removing it from board files/driver files here. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-04-15sunxi: usbc: Wait for vbus to fall after disabling itHans de Goede
When u-boot boots the board may be powering vbus, we turn off vbus in sunxi_usbc_request_resources, if we are too quick with reading vusb-detect after this we may see a residual charge and assume we've an external vusb connected even though we do not. So when we see an external vusb wait a bit and try again. Without this when dealing with a pmic controller vbus and doing "reset" on the u-boot console the musb host will only init once every other boot, because the other boot it thinks an external vbus is present, this commit fixes this.

2015-04-15sunxi: usbc: Initialize vusb value on request_resourcesHans de Goede
On boards which use the pmic to enable/disable vbus on the otg port, the vbus value is not reset to 0 on reset, as reset only resets the SoC and not the pmic, so explicitly set vbus to 0 on init (request_resources) by moving the gpio_direction_output call into request_resources. For consistency also move the gpio_direction_input call for vbus-detect into request_resources. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2015-04-15sunxi: common VBUS detection logic in usbcPaul Kocialkowski
VBUS detection could be needed not only by the musb code (to prevent host mode), but also by e.g. gadget drivers to start only when a cable is connected. In addition, this allows more flexibility in vbus detection, as it could easily be extended to other USBC indexes. Eventually, this would help making musb support independent from a hardcoded USB controller index (0).

2015-04-14ARM: bcm2835: implement phys_to_bus/bus_to_physStephen Warren
The BCM283[56] contain both a L1 and L2 cache between the GPU (a/k/a VideoCore CPU?) and DRAM. DMA-capable peripherals can also optionally access DRAM via this same L2 cache (although they always bypass the L1 cache). Peripherals select whether to use or bypass the cache via the top two bits of the bus address. An IOMMU exists between the ARM CPU and the rest of the system. This controls whether the ARM CPU's accesses use or bypass the L1 and/or L2 cache. This IOMMU is configured/controlled exclusively by the VideoCore CPU. In order for DRAM accesses made by the ARM core to be coherent with accesses made by other DMA peripherals, we must program a bus address into those peripherals that causes the peripheral's accesses to use the same set of caches that the ARM core's accesses will use. On the RPi1, the VideoCore firmware sets up the IOMMU to enable use of the L2 cache. This corresponds to addresses based at 0x40000000. On the RPi2, the VideoCore firmware sets up the IOMMU to disable use of the L2 cache. This corresponds to addresses based at 0xc0000000. This patch implements U-Boot's phys_to_bus/bus_to_phys APIs according to those rules.

Since commit 79d75d752717 (ARM: move -march=* and -mtune= options to arch/arm/Makefile), all the Tegra boards are broken because the SPL is built for ARMv7. Insert Tegra-specific code to arch/arm/Makefile to set compiler flags for an earlier ARM architecture. Note: The v1 patch for commit 79d75d752717 *was* correct when it was submitted. Notice it was originally written for multi .config configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for Tegra U-Boot Main/SPL, respectively. But, until it was merged into the mainline, commit e02ee2548afe (kconfig: switch to single .config configuration) had been already applied there.

This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is. In its turn if it deals with binary image of U-Boot there's no way for pre-bootloader to get required value. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
