Thanks for the bug report and the test program. The fix seems straightforward
-- just adjust what we return for the register value. I've sent a patch:

SIE-200 (TrustZone) MPC: BLK_MAX returns an incorrect value
Status in QEMU:
$ qemu-system-arm --version
QEMU emulator version 3.0.92 (v3.1.0-rc2-31-gd522fba244)
Arm SIE-200 Technical Reference Manual describes that BLK_MAX
indicates the maximum value of "block based index register" (BLK_IDX).
For example, the value 1 would indicate that BLK_IDX can be 0 or 1.
According to my experiments, the AN505 FPGA image apparently follows
In the current implementation of QEMU, it appears to indicate the
number of possible values for BLK_IDX, i.e., one plus the value it's
supposed to return.
