      ARM: ux500: simplify secondary CPU boot · c00def71
      Linus Walleij authored
      This removes a lot of ancient cruft from the Ux500 SMP boot.
      Instead of the pen grab/release, just point the ROM to
      secondary_boot() and start the second CPU there, then send
      the IPI.
      
      Use our own SMP enable method. This enables us to remove the
      last static mapping and get both CPUs booting properly.
      
      Tested this and it just works.

      ARM: ux500: add an SMP enablement type and move cpu nodes · bf64dd26
      Linus Walleij authored
      The "cpus" node cannot be inside the "soc" node, while this
      works for the CoreSight blocks, the early boot code will look
      for "cpus" directly under the root node, so this is a hard
      convention. So move the CPU nodes.
      
      Augment the "reg" property to match what is actually in the
      hardware: 0x300 and 0x301 respectively.
      
      Then add an SMP enablement type to be used by the SMP init
      code, "ste,dbx500-smp".

      ARM: OMAP2+: hwmod: Fix _wait_target_ready() for hwmods without sysc · 9a258afa
      Roger Quadros authored
      For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so
      _find_mpu_rt_port(oh) will return NULL thus preventing ready state check
      on those modules after the module is enabled.
      
      This can potentially cause a bus access error if the module is accessed
      before the module is ready.
      
      Fix this by unconditionally calling _init_mpu_rt_base() during hwmod
      _init(). Do ioremap only if we need SYSC access.
      
      Eventhough _wait_target_ready() check doesn't really need MPU RT port but
      just the PRCM registers, we still mandate that the hwmod must have an
      MPU RT port if ready state check needs to be done. Else it would mean that
      the module is not accessible by MPU so there is no point in waiting
      for target to be ready.
      
      e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

      Merge "drop few more legacy boards for v4.3" from Tony Lindgren:
      
      Drop more omap3 legacy board-*.c files for v4.3. This time we're
      dropping the board files for omap3logic and omap3pandora.
      
      The reason for dropping these now rather than later is that now
      we can simply revert the patches in case of unexpected issues as
      we are not dropping any platform data at this point.
      
      This leaves us with only the following board-*.c files:
      
      BOARD                   REASON NEEDED
      board-ldp.c             Still used in RMKs boot test system
      board-rx51-*.c          Needs /proc/atags support for user space
      
      Once we have the n900 legacy user space issues sorted out for
      /proc/atags and system_rev, we can drop the remaining two
      board-*.c files. And then one merge window after that we can
      drop the legacy booting support assuming no unexpected issues
      are found.
