      Synchronise arch.h and arch_helpers.h with TF-A-Tests · 932b3ae2
      Antonio Nino Diaz authored
      
      
      The headers forked at some point in the past and have diverged a lot. In
      order to make it easier to share code between TF-A-Tests and TF-A, this
      patch synchronises most of the definitions in the mentioned headers.
      
      This is not a complete sync, it has to be followed by more cleanup.
      
      This patch also removes the read helpers for the AArch32 instructions
      ats1cpr and ats1hr (they are write-only).

      rpi3: add RPI3_USE_UEFI_MAP build option · 4dcf1fad
      Pete Batard authored
      
      
      The default Raspberry Pi 3 memory mapping for ATF is geared towards
      the use of uboot + Linux. This creates issues when trying to use
      ATF with an UEFI payload and Windows on ARM64.
      
      We therefore introduce new build option RPI3_USE_UEFI_MAP, that
      enables the build process to use an alternate memory mapping that
      is compatible with UEFI + Windows (as well as UEFI + Linux).

      allwinner: power: Add DCDC6 power rail · 793c38f0
      Andre Przywara authored
      
      
      The DCDC6 power rail is typically driving VDD_SYS in the SoC, so it is
      on by default and uses the default voltage.
      
      As there seems to be at least on board using a different voltage, add
      the rail to the list of known voltage lines, so we can setup the right
      voltage as early as possible.

      allwinner: power: add enable switches for DCDC1/5 · a561e41b
      Andre Przywara authored
      
      
      The DCDC1 and DCDC5 power rails didn't specify the enable bits. This
      isn't critical, since those rails are on by default (and are needed for
      every board), but it is inconsistent.
      
      Add the respective enable bits for those two rails.

      allwinner: power: fix DRIVEVBUS pin setup · d93eb446
      Andre Przywara authored
      
      
      The DRIVEVBUS pin setup was broken in two ways:
      - To configure this pin as an output pin, one has to *clear* the bit in
        register 0x8f. It is 0 by default, but rebooting from Linux might have
        left this bit set.
      - Doing this just configures the pin as an output pin, but doesn't
        actually drive power to it. This is done via bit 2 in register 0x30.
      
      Fix the routine to both properly configure the pin and drive power to
      it. Add an axp_clrsetbits() helper on the way.
      
      Now this isn't really perfect, still:
      We only need to setup the PMIC power rails that are needed for U-Boot.
      DRIVEVBUS typically controls the VBUS voltage for the host function of
      an USB-OTG port, something we typically don't want in U-Boot (fastboot,
      using the USB *device* functionality, is much more common). The
      BananaPi-M64 uses the regulator in this way, but the Remix Mini PC
      actually controls the power of both its USB ports via this line.
      
      Technically we should differentiate here: if DRIVEVBUS controls a
      microUSB-B socket, the power should stay off, any host-type A sockets
      should be supplied, though.
      For now just always enable the power, that shouldn't really hurt the
      USB-OTG functionality anyway.

      allwinner: A64/H5: setup missing bus clocks · 19a7507a
      Andre Przywara authored
      
      
      The legacy Allwinner ATF port used to setup some clocks, and U-Boot is
      still relying on this. We don't need to setup the full set, as the SPL
      is doing most of it, but it misses one clock (AHB2) and programs another
      (AHB1) to quite conservative values.
      
      Fix this up during the platform setup to improve USB and Ethernet
      performance, iperf values go up by 31% in my setup with that patch.

      SPM: Register Secure Partition priority level with ehf module · 5681b292

      Register a priority level, PLAT_SP_PRI, for secure partition with EL3
      exception handling framework(ehf) module.
      
      The secure partition manager(SPM) would raise the core's priority to
      PLAT_SP_PRI before entering the secure partition, to protect the core
      from getting interrupted while in secure partition.

      rpi3: add RPI3_RUNTIME_UART build option · 6d5c61de
      Pete Batard authored
      
      
      Some OSes (e.g. Ubuntu 18.04 LTS on Raspberry Pi 3) may disable the
      runtime UART in a manner that prevents the system from rebooting if
      ATF tries to send runtime messages there.
      
      Also, we don't want the firmware to share the UART with normal
      world, as this can be a DoS attack vector into the secure world.
      
      This patch fixes these 2 issues by introducing new build option
      RPI3_RUNTIME_UART, that disables the runtime UART by default.

      This patch enabled PIE for FVP when RESET_TO_BL31=1. The references
      to BL31_BASE are replaced by BL31_START as being a symbol exported by
      the linker, will create a dynamic relocation entry in .rela.dyn and
      hence will be fixed up by dynamic linker at runtime. Also, we disable
      RECLAIM_INIT_CODE when PIE is enabled as the init section overlay
      creates some static relocations which cannot be handled by the
      dynamic linker currently.

      Add helper to return reference to a symbol · 6a7b3005
      Soby Mathew authored
      
      
      This patch adds a utility function to return
      the address of a symbol. By default, the compiler
      generates adr/adrp instruction pair to return
      the reference and this utility is used to override
      this compiler generated to code and use `ldr`
      instruction.
      
      This is needed for Position Independent Executable
      when it needs to reference a symbol which is constant
      and does not depend on the execute address of the
      binary.
      
      For example, on the FVP, the GICv3 register context is
      stored in a secure carveout (arm_el3_tzc_dram) within
      DDR and does not relocate with the BL image. Now if
      BL31 is executing at a different address other than
      the compiled address, using adrp/adr instructions to
      reference this memory will not work as they generate an
      address that is PC relative. The way to get around this
      problem is to reference it as non-PC relative (i.e
      non-relocatable location) via `ldr` instruction.
