Doing so breaks Raspberry Pis with -VL805 XHCI controllers lacking dedicated SPI EEPROMs, which have been -used for USB booting but then need to be reset so that the kernel -can reconfigure them. The lack of a reset causes the firmware's loading -of the EEPROM image to RAM to fail, breaking USB for the kernel. - -See: https://www.raspberrypi.org/forums/viewtopic.php?p=1758157#p1758157 - -Fixes: 04356ac30771 ("PCI: brcmstb: Add bcm7278 PERST# support") - -[1] 04356ac30771 ("PCI: brcmstb: Add bcm7278 PERST# support") - -Signed-off-by: Phil Elwell <phil@raspberrypi.com> ---- - drivers/pci/controller/pcie-brcmstb.c | 2 ++ - 1 file changed, 2 insertions(+) - ---- a/drivers/pci/controller/pcie-brcmstb.c -+++ b/drivers/pci/controller/pcie-brcmstb.c -@@ -877,6 +877,8 @@ static int brcm_pcie_setup(struct brcm_p - - /* Reset the bridge */ - pcie->bridge_sw_init_set(pcie, 1); -+ pcie->perst_set(pcie, 1); -+ - usleep_range(100, 200); - - /* Take the bridge out of reset */ |
