This patch adds support for enabling or disabling the lane swapping (called "port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY device. One use case is when bootstrap configuration enables this feature (because of e.g. LED_0 wrong wiring) so then one needs to disable it in software (at u-boot/Linux).

2018-10-03riscv: Add QEMU virt board supportBin Meng
This adds QEMU RISC-V 'virt' board target support, with the hope of helping people easily test U-Boot on RISC-V. The QEMU virt machine models a generic RISC-V virtual machine with support for the VirtIO standard networking and block storage devices. It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and it also uses device-tree to pass configuration information to guest software. It implements RISC-V privileged architecture spec v1.10. Both 32-bit and 64-bit builds are supported. Support is pretty much preliminary, only booting to U-Boot shell with the UART driver on a single core. Booting Linux is not supported yet.

This patch removes those references to armv5, since by now newer compilers are required which should have armv7 support enabled. The Makefile also also has a list of options for mtune, but the entry for CONFIG_CPU_V7A is empty, so this patch tunes the CPU_V7A architecture to generic-armv7-a.

2018-08-20x86: coreboot: Add generic coreboot payload supportBin Meng
Currently building U-Boot as the coreboot payload requires user to change the build configuration for a specific board during menuconfig process. This uses the board's native device tree to configure the hardware. For example, the device tree provides PCI address range for the PCI host controller and U-Boot will re-program all PCI devices' BAR to be within this range. In order to make sure we don't mess up the hardware, we should guarantee the range matches what coreboot programs the chipset. But we really should make the coreboot payload support easier. Just like EFI payload, we can create a generic coreboot payload for all x86 boards as well. The payload is configured to include as many generic drivers as possible. All stuff that touches low level initialization are not allowed as such is the coreboot's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.
