9 years agousb: board_usb_init and board_usb_cleanup calls in the fastboot command

usb: board_usb_init and board_usb_cleanup calls in the fastboot command

Each USB download function command calls board_usb_init before registering the
USB gadget and board_usb_cleanup after de-registering it. On devices currently
using fasboot, musb-new is usually initialized earlier, but some other boards
might need the board_usb_init call to properly initialize musb-new.

This requires adding an argument (the USB controller index) to the fastboot
command, as it is currently done with other USB download gadget functions.

9 years agopci: Configure expansion ROM during auto config process
Bin Meng [Wed, 8 Jul 2015 05:06:40 +0000 (13:06 +0800)]
pci: Configure expansion ROM during auto config process

Currently PCI expansion ROM address is assigned by a call to
pciauto_setup_rom() outside of the pci auto config process.
This does not work when expansion ROM is on a device behind
PCI bridge where bridge's memory limit register was already
programmed to a value that does not cover the newly assigned
expansion ROM address. To fix this, we should configure the
ROM address during the auto config process.
