      ARM: 7012/1: Set proper TEXT_OFFSET for newer MSMs · 9e775ad1
      Stephen Boyd authored
      MSMs post 8x50 have 2Mb at the beginning of RAM reserved for
      shared memory. Since the kernel hasn't typically been told this
      RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory
      atags passed to the kernel have matched. This doesn't play nicely
      with things such as AUTO_ZRELADDR, which doesn't work at all, and
      dynamic phys to virt, which requires an MSM specific workaround.
      
      Work around these issues by telling the kernel RAM starts at
      0xN0000000 (it actually does) and fixup the atags from the
      bootloader (if necessary) to say the same. In addition, make sure
      to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that
      the kernel doesn't end up being decompressed into shared memory.
      
      After doing this, AUTO_ZRELADDR should work on MSM with no
      problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be
      necessary.
