Hi all,
The attached patches fix up a minor noise issue if a board defines its own value for CONFIG_BOOTP_VCI_STRING, makes sure we do not hit any noise on vexpress and port to the distro boot configs while maintaining the existing boot setup.
I have built and tested for vexpress_ca15_tc2 using qemu-system-arm, however I hit a snag with an illegal instruction. U-Boot 2015.07-rc2-00140-gef0f2f5-dirty (Jun 27 2015 - 06:42:35 -0500)

In the end my goal here is to have a u-boot that works with qemu-system-arm so that the user never needs to extract files out of the system in order to get a booting vm. The answer may well be to make a virt specific u-boot that can set the amount of ram, cpu, etc based on what qemu tells it is there.
