[PATCH v2 15/24] hw/arm/mps2-tz: Allow boards to have different PPCInfo


From: Peter Maydell
Subject: [PATCH v2 15/24] hw/arm/mps2-tz: Allow boards to have different PPCInfo data
Date: Mon, 15 Feb 2021 11:51:29 +0000

The AN505 and AN521 have the same device layout, but the AN524 is
somewhat different.  Allow for more than one PPCInfo array, which can
be selected based on the board type.

We can't just put the arrays at file-scope and set up pointers
to them in the MPS2TZMachineClass struct, because the array
members include entries like "&mms->uart[0]" which is only valid
inside the mps2tz_common_init() function.
