From dea25842ab72427fde250992da1d29c2fbc256f8 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sat, 25 Jun 2022 11:02:32 -0400 Subject: [PATCH] usb: ohci-hcd: Remove some unused legacy code At this point, the only user of ohci-hcd that also uses PCI is using DM, so we can drop CONFIG_PCI_OHCI* usage. No platforms set either of CONFIG_SYS_USB_OHCI_BOARD_INIT or CONFIG_SYS_USB_OHCI_CPU_INIT so those hooks can be removed as well.
