The register group QSPI_SPI_DATA_REG_3, QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is treated as a single 128-bit word for shifting data in and out. The bit at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out in case of 128 bit transfer mode. Therefore the first byte to be written to flash should be at QSPI_SPI_DATA_REG_3[31-25] position. Instead of writing 1 byte at a time when interacting with SPI NOR flash, make use of all the four registers so that 16 bytes can be transferred in one go. With this patch, the flash write speed increases from ~250KBs/ to ~650KB/s on DRA74 EVM.

This ignores the fact that compatible strings in the device tree are listed in order of priority - that is, if we have a node with 2 compatible strings & a driver that matches each then we should always probe the driver that matches the first compatible string. Fix this by looping through the compatible strings for a node when attempting to bind it in lists_bind_fdt and checking each driver for a match of the first string, then each driver for a match of the second string etc. Effectively this inverts the loops over compatible strings & drivers.

This was being done by checking whether the parent of the device is of the UCLASS_ROOT class. This causes problems if the PCI controller is a child of some other non-PCI node, for example a simple-bus node. For example, if the device tree contains something like the following then pci_uclass_pre_probe would incorrectly believe that the PCI controller is a bridge, with a PCI parent: / { some_child { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <1>; ranges = <>; pci_controller: pci@10000000 { compatible = "my-pci-controller"; device_type = "pci"; reg = <0x10000000 0x2000000>; }; }; }; Avoid this incorrect detection of bridges by instead checking whether the parent devices class is UCLASS_PCI and treating a device as a bridge when this is true, making use of device_is_on_pci_bus to perform this test.

| * | | pci: xilinx: Add a driver for Xilinx AXI to PCIe bridgePaul Burton2016-09-21-0/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a driver for the Xilinx AXI bridge for PCI express, an IP block which can be used on some generations of Xilinx FPGAs. This is mostly a case of implementing PCIe ECAM specification, but with some quirks about what devices are valid to access.

An alternative to this commonly used with Linux is to reference a clock via a phandle. This patch allows U-Boot to support that, retrieving the clock frequency by probing the appropriate clock device. For example, a system might choose to provide the UART base clock as a reference to a clock common to multiple devices: sys_clk: clock { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <10000000>; }; uart0: uart@10000000 { compatible = "ns16550a"; reg = <0x10000000 0x1000>; clocks = <&sys_clk>; }; uart1: uart@10000000 { compatible = "ns16550a"; reg = <0x10001000 0x1000>; clocks = <&sys_clk>; }; This removes the need for the frequency information to be duplicated in multiple nodes and allows the device tree to be more descriptive of the system.
