[U-Boot-Users] [PATCH] fix USB devices with multiple configurations
by Harald Welte 10 Jul '08

10 Jul '08

This patch fixes bugs in usbdcore*.c related to the use of devices with multiple configurations. The original code made mistakes about the meaning of configuration value and configuration index, and the resulting off-by-one errors resulted in: * SET_CONFIGURATION always selected the first configuration, no matter what wValue is being passed. * GET_DESCRIPTOR/CONFIGURATION always returned the descriptor for the first configuration (index 0).

[U-Boot-Users] [PATCH] pci: Move PCI device configuration check into a separate weak function
by Stefan Roese 10 Jul '08

10 Jul '08

This patch moves the check, if a device should be skipped in PCI PNP configuration into the function pci_skip_dev(). This function is defined as weak so that it can be overwritten by a platform specific one if needed. The check if the device should get printed in the PCI summary upon bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function pci_print_dev() which is also defined as weak too.
