[U-Boot] [PATCH 1/4] pxe: allow compilation when !defined(CONFIG_CMD_NET)
pxe.c provides both the "pxe" command which relies on a network, and the "sysboot" command which doesn't. Fix the file to compile when network support isn't enabled. This is useful e.g. on the Raspberry Pi which has no network support yet, but will soon support the sysboot command.
Signed-off-by: Stephen Warren swarren@wwwdotorg.org --- This patch doesn't appear to depend on anything much, but is needed by the rest of this series. Given the dependencies in the rest of this series, either (a) this one patch can be applied to u-boot/master, and then u-boot/arm can merge that in before the rest of the series, or (b) u-boot/master can be merged into u-boot-arm/master, then this whole series applied there. --- common/cmd_pxe.c | 11 +++++++++++ 1 file changed, 11 insertions(+)

Modify the rpi_b board to include the "distro defaults" header, so that all the config options distros expect are enabled. Remove any #defines that enable the same options from the rpi_b.h.

The Pi has no flash to store an environment in the usual fashion. However, the user may wish to customize the environment. We know that the SD card must be present, since that's where the boot ROM has loaded U-Boot from. So, load uEnv.txt from there early during boot. This allows the user to e.g. customize boot_targets, in order to automatically select network boot.

Rework rpi_b's bootcmd (and sub-commands) to match Tegra's bootcmd as much as possible. This will aid in a future patch which will create a common header e.g. config_distro_bootcmd.h.
While at it, enable booting from extlinux.conf using the sysboot command.
The iteration and componentization currently makes a little more sense for Tegra than RPi, but I'd still like to keep the two as similar as possible. USB and networking support is coming to the RPi in due course, and it'll all make more sense then anyway.
