[U-Boot] [PATCH v2 0/6] Board for QEMU's '-machine virt' on ARM

[Tuomas Tynkkynen]

These patches add a board for running U-Boot under QEMU's '-machine virt'
emulation, thus making it possible to boot Linux distros that use the
extlinux.conf booting method under '-machine virt'.

To some extent, this is currently possible by emulating and running
U-Boot on some of the Versatile boards, but (IIRC) they have some
limitations like limiting to 1GB of RAM or lacking support for PCI.

Changes in v2:
 - Introduce helper functions for implementing memory-mapped PCI config
   space accesses + refactor two existing drivers to use them.
 - Addresses Bin Meng's review comments (in patches 4 & 5)
 - Hook up test.py to run on Travis CI (patch 6). This requires
   https://github.com/swarren/uboot-test-hooks/pull/14 to go in first.

Travis run with the uboot-test-hooks hacked to point to my local
repository: https://travis-ci.org/dezgeg/u-boot/builds/276392558

Tuomas Tynkkynen (6):
  pci: Add helper for implementing memory-mapped config space accesses
  pci: xilinx: Use pci_generic_mmap_{read,write}_config()
  pci: layerscape: Use pci_generic_mmap_{read,write}_config
  PCI: Add driver for a 'pci-host-ecam-generic' host controller
  ARM: Add a new arch + board for QEMU's 'virt' machine
  travis.yml: Add job for running test.py in qemu_arm
