2016-01-29distro bootcmd: enumerate PCI before network operationsStephen Warren
The PCI bus must be enumerated before PCI devices, such as Ethernet devices, are known to U-Boot. Enhance the distro boot commands to perform PCI enumeration when needed. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-01-29distro bootcmd: make net boot only optionally start USBStephen Warren
Currently, the distro boot commands always enumerate USB devices before performing network operations. However, depending on the board and end- user configuration, network devices may not be attached to USB, and so enumerating USB may not be necessary. Enhance the scripts to make this step optional, so that the user can decrease boot time if they don't need USB. This change is performed by moving the "usb start" invocation into a standalone variable. If the user desires, they can replace that variable's value with some no-op command such as "true" instead. Booting from a USB storage device always needs to enumerate USB devices, so this action is still hard-coded.

2015-03-28Document config_distro_bootcmd environment variables for interactive booting.Karsten Merker
config_distro_bootcmd.h defines a common boot environment for multiple platforms, including several environment variables that are intended for interactive use by an end-user. Document which variables are considered public interfaces that must remain compatible in future u-boot versions.

2015-01-30add README.distro fileDennis Gilmore
Add documentation on how to setup a system to use the generic distro configs and boot commands. This spells out what is needed to make a system conformant, but does not limit the board to only the defaults.
