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.

The FPGA configuration is encoded in the high byte of MISCREG_EMU_REVID. Configs GPU and MAX (encoded as 2 and 3) support the ISO SMMU, while BASE (encoded as 1) does not. This patch implements this encoding and returns the proper number of SMMU instances. Change-Id: I024286b6091120c7602f63065d20ce48bcfd13fe Signed-off-by: Steven Kao <skao@nvidia.com>

System suspend sequence involves initializing the SMMU as a part of the system suspend exit, which is currently not present for Tegra194 platform. Thus call tegra_smmu_init() as a part of system suspend exit. Change-Id: I3086301743019e05a40fd221372e7f8713f286ae Signed-off-by: Vignesh Radhakrishnan <vigneshr@nvidia.com>

Fake system suspend for Tegra194, calls the routine tegra_secure_entrypoint() instead of calling WFI. In essence, this is a debug mode that ensures that the code path of kernel->ATF and back to kernel is executed without depending on other components involved in the system suspend path. This is for ensuring that verification of system suspend can be done on pre-silicon platforms without depending on the rest of the layers being enabled.

* changes: mediatek: mt8183: Fix AARCH64 init fail on CPU0 mediatek: mt8183: refine GIC driver for low power scenarios
-
James Liao authored
CPU0 is default on, so it doesn't need to run pwr_domain_on() at boot. CPU0 AARCH64 will be set in pwr_domain_suspend(), but it may encounter race condition with other CPUs. Now AARCH64 will be set with cluster on in pwr_domain_on(), and all CPUs on this cluster will be set together. It doesn't need to set AARCH64 again in pwr_domain_suspend(), so the race condition can be avoided.

ROMLIB extract functions code from BL images to put them inside ROM. This has for effect to reduce the size of the BL images. This patch take this size reduction into consideration to optimize the memory layout of BL2. A new "PLAT_ARM_BL2_ROMLIB_OPTIMIZATION" macro is defined and used to reduce "PLAT_ARM_MAX_BL2_SIZE". This allows to remove the gap between BL1 and BL2 when ROMLIB is used and provides more room for BL31. The current memory gain is 0x6000 for fvp and 0x8000 for juno.

Arm's GIC-600 features a Power Register (GICR_PWRR), which needs to be programmed to enable redistributor operation. Section 3.6.1 in the GIC-600 TRM describes the power-up and power-down sequence in pseudo code, which deviates from the current TF-A implementation in drivers/arm/gic/v3/gic600.c. For powering on a redistributor, the pseudo code suggests to loop over the whole sequence (check for transition, write request bit) instead of just looping over the ready bit read as TF-A does in gic600_pwr_on(). This patch fixes GIC-600 power up sequence according to the TRM. Change-Id: I445c480e96ba356b69a2d8e5308ffe6c0a97f45b Signed-off-by: Alexei Fedorov <Alexei.Fedorov@arm.com>

Previous implementation of timers assumed that clk_div has pretty representation in MHz (10MHz, 100MHz, etc). Unusual frequencies (99.99MHz) were causing assertion error and made udelay unusable.

The pre-processor directives make it hard to read the non-TBB version of this function. Refactor the code to improve readability. No functional change introduced. In particular, introduce a new helper function load_image_flush(), that simply loads an image and flushes it out to main memory. This is the only thing load_auth_image_internal() needs to do when TBB is disabled or when authentication is dynamically disabled. In other cases, we need to recursively authenticate the parent images up to the root of trust. To make this clearer, this code gets moved to a TBB-specific helper function called load_auth_image_recursive(). As a result, load_auth_image_internal() now boils down to calling the right helper function (depending on TBB enablement and dynamic authentication status).
