[PATCH 0/6] hw/arm: Fix modelling of SSE-300 TCMs and SRAM

[Peter Maydell]

This patchset fixes some bugs in how we were modelling the
TCMs and the SRAM in the SSE-300 which were preventing
Arm TF-M from booting on our AN547 model; there are also
some fixes to things I noticed while I was in the code.

The specific bugs preventing boot were:
 * SRAM_ADDR_WIDTH for the AN547 is 21, not 15, so the SRAM
   area was too small
 * we were putting the SRAMs at the wrong address (0x2100_0000
   for SSE-300, not 0x2000_0000 as for SSE-200)

The other stuff I've fixed is:
 * we were modelling the SRAM in the AN524 both in the SSE
   and in the board model (harmlessly, as the board-model
   memory was just always shadowed in the memory map and
   unreachable)
 * we were modelling the TCMs in the AN547 board model,
   which is conceptually wrong because in hardware they're
   part of the SSE-300. No guest-visible change, but it will
   avoid problems if/when we add another SSE-300 board model

thanks

  hw/arm/armsse: Convert armsse_realize() to use ERRP_GUARD
  hw/arm/mps2-tz: Allow board to specify a boot RAM size
  hw/arm: Model TCMs in the SSE-300, not the AN547
