      plat/arm: Migrate AArch64 port to the multi console driver · 2f18aa1f
      Antonio Nino Diaz authored
      
      
      The old API is deprecated and will eventually be removed.
      
      Arm platforms now use the multi console driver for boot and runtime
      consoles. However, the crash console uses the direct console API because
      it doesn't need any memory access to work. This makes it more robust
      during crashes.
      
      The AArch32 port of the Trusted Firmware doesn't support this new API
      yet, so it is only enabled in AArch64 builds. Because of this, the
      common code must maintain compatibility with both systems. SP_MIN
      doesn't have to be updated because it's only used in AArch32 builds.
      The TSP is only used in AArch64, so it only needs to support the new
      API without keeping support for the old one.
      
      Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
      causes the UARTs to reset (except for the one used by the TSP). This
      means that they must be unregistered when suspending and re-registered
      when resuming. This wasn't a problem with the old driver because it just
      restarted the UART, and there were no problems associated with
      registering and unregistering consoles.
      
      The size of BL31 has been increased in builds with SPM.

      bl2-el3: Add BL2 at EL3 support in FVP · 81528dbc
      Roberto Vargas authored
      
      
      This patch add supports for the new API added for BL2 at EL3 for
      FVP. We don't have a non-TF Boot ROM for FVP, but this option can be
      tested setting specific parameters in the model.
      
      The bl2 image is loaded directly in memory instead of being loaded
      by a non-TF Boot ROM and the reset address is changed:
      
      	--data cluster0.cpu0=bl2.bin@0x4001000
      	-C cluster0.cpu0.RVBAR=0x4001000
      
      These parameters mean that in the cold boot path the processor will
      jump to BL2 again. For this reason, BL2 is loaded in dram in this
      case, to avoid other images reclaiming BL2 memory.
