Subject: [PATCH 0/6] hw/arm: Fix modelling of SSE-300 TCMs and SRAM
Date: Mon, 10 May 2021 20:08:38 +0100 [thread overview]
Message-ID: <20210510190844.17799-1-peter.maydell@linaro.org> (raw)
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
