zynqmp qemmu bug CSU_MULTI_BOOT register

Hi,

I couldn't find a better place to report a bug, so I publish it here in this forum. I hope it will reach the people in charge.

The register CSU_MULTI_BOOT (0xffca0010) is reset when a system reset is applied in QEMU for zynqmp. This contradicts both the documentation and the very usage of this register.

This bug may be corrected by modifying the line 421 of the file hw/misc/csu_core.c (in the current state of the master branch) as this:

original line: },{ .name = "CSU_MULTI_BOOT", .decode.addr = A_CSU_MULTI_BOOT,

corrected line: },{ .name = "CSU_MULTI_BOOT", .decode.addr = A_CSU_MULTI_BOOT, .inhibit_reset = 0xffffffff,

Best regards,
