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
