2015-07-21musb: Allow musb_platform_enable to return an error codeHans de Goede
Allow musb_platform_enable to return an error code and propagate it up to usb_lowlevel_init(). This allows moving the checks for an external vbus being present to be moved from platform_init to platform_enable, so that the user can unplug a charger, plug in a host adapter with a usb-device, do a "usb reset" and have things working. This also allows adding a check for the id-pin to platform_enable, so that it can short circuit the 1s delay in usb_lowlevel_init() when no host cable is plugged in and thus waiting for a device to show up is useless. Note that all the changes to code shared with the kernel are wrapped in the kernel. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-02-24usb: musb-new: omap2430: Reset the MUSB controller earlyPaul Kocialkowski
When booting from USB peripheral boot, the bootrom will not properly deinit the MUSB controller, which doesn't clearly indicate an USB disconnection to the host and leaves U-Boot to deal with the state of the previous USB session. On some host controller drivers (e.g. xhci_hcd), this ends up in a failure during set address, caused by the lack of proper disconnection notification. Resetting the controller early in U-Boot notifies the host of the disconnection and doesn't hurt other use cases.

2014-09-16kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada
U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.
