      Tegra194: memctrl: add support for MIU4 and MIU5 · a69a30ff
      Pravin authored
      
      
      This patch adds support for memqual miu 4,5.
      
      The MEMQUAL engine has miu0 to miu7 in which miu6 and
      miu7 is hardwired to bypass SMMU. So only miu0 to miu5
      support is provided.

      Tegra194: memctrl: remove support to reconfigure MSS · 4b74f6d2
      Stefan Kristiansson authored
      
      
      As bpmp-fw is running at the same time as ATF, and
      the mss client reconfiguration sequence involves performing
      a hot flush resets on bpmp, there is a chance that bpmp-fw is
      trying to perform accesses while the hot flush is active.
      
      Therefore, the mss client reconfigure has been moved to
      System Suspend resume fw and bootloader, and it can be
      removed from here.

      Tegra194: memctrl: lock mc stream id security config · 56e7d6a7
      Pritesh Raithatha authored
      
      
      This patch locks most of the stream id security config registers as
      per HW guidance.
      
      This patch keeps the stream id configs unlocked for the following
      clients, to allow some platforms to still function, until they make
      the transition to the latest guidance.

      Tegra194: memctrl: fix logic to check TZDRAM config register access · 95397d96
      Steven Kao authored
      
      
      This patch fixes the logic to check if the previous bootloader has
      disabled access to the TZDRAM configuration registers. The polarity
      for the bit was incorrect in the previous check.

      Tegra194: memctrl: platform handler for TZDRAM setup · 4e697b77
      Steven Kao authored
      
      
      This patch provides the platform with flexibility to perform custom
      steps during TZDRAM setup. Tegra194 platforms checks if the config
      registers are locked and TZDRAM setup has already been done by the
      previous bootloaders, before setting up the fence.

      Puneet Saxena authored
      
      
      This patch enables IO coherency for SE clients, SEWR and SERD,
      by overriding their platform settings to "normal_coherent".
      This setting also converts read/write requests from these SE
      clients to Normal type.

      Fix invalid use of function pointer [Rule 1.3]
      
      Added explicit casts (e.g. 0U) to integers in order for them to be
      compatible with whatever operation they're used in [Rule 10.1]
      
      convert object type to match the type of function parameters
      [Rule 10.3]
      
      Force operands of an operator to the same type category [Rule 10.4]
      
      Fix implicit widening of composite assignment [Rule 10.6]
      
      Fixed if statement conditional to be essentially boolean [Rule 14.4]
      
      Added curly braces ({}) around if statements in order to
      make them compound [Rule 15.6]
      
      Voided non c-library functions whose return types are not used
      [Rule 17.7]

      Tegra194: program stream ids for XUSB · bc019041
      Ajay Gupta authored
      
      
      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.
