T194 XUSB has support for XUSB virtualization. It will have one physical function (PF) and four Virtual function (VF) There were below two SIDs for XUSB until T186. 1) #define TEGRA_SID_XUSB_HOST 0x1bU 2) #define TEGRA_SID_XUSB_DEV 0x1cU We have below four new SIDs added for VF(s) 3) #define TEGRA_SID_XUSB_VF0 0x5dU 4) #define TEGRA_SID_XUSB_VF1 0x5eU 5) #define TEGRA_SID_XUSB_VF2 0x5fU 6) #define TEGRA_SID_XUSB_VF3 0x60U When virtualization is enabled then we have to disable SID override and program above SIDs in below newly added SID registers in XUSB PADCTL MMIO space. These registers are TZ protected and so need to be done in ATF. a) #define XUSB_PADCTL_HOST_AXI_STREAMID_PF_0 (0x136cU) b) #define XUSB_PADCTL_DEV_AXI_STREAMID_PF_0 (0x139cU) c) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_0 (0x1370U) d) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_1 (0x1374U) e) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_2 (0x1378U) f) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_3 (0x137cU) This change disables SID override and programs XUSB SIDs in above registers to support both virtualization and non-virtualization.
