On 32-bit platforms this value cannot exceed 32. On 64-bit platforms this value cannot exceed 64. - The Access Size field is used to determine whether byte, WORD, DWORD, or QWORD accesses are to be used. QWORD accesses are only valid on 64-bit architectures. Documentation for the ARM PL011 at https://developer.arm.com/documentation/ddi0183/latest/ states that the registers are: - spaced 4 bytes apart (see Table 3-2), so register stride must be 32. - 16 bits in size in some cases (see individual registers), so access size must be at least 2. Linux doesn't seem to care about this error in the table, but it does affect at least the NOVA microhypervisor. In theory we therefore have a choice between reporting the access size as 2 (16 bit accesses) or 3 (32-bit accesses). In practice, Linux does not correctly handle the case where the table reports the access size as 2: as of kernel commit 750b95887e5678, the code in acpi_parse_spcr() tries to tell the serial driver to use 16 bit accesses by passing "mmio16" in the option string, but the PL011 driver code in pl011_console_match() only recognizes "mmio" or "mmio32". The result is that unless the user has enabled 'earlycon' there is no console output from the guest kernel. We therefore choose to report the access size as 32 bits; this works for NOVA and also for Linux. It is also what the UEFI firmware on a Raspberry Pi 4 reports, so we're in line with existing real-world practice.

This happened as a result of commit 6ec1588e in 2014, which changed "we always map the RAM to the low addresses for vexpress-a9" to "we always map flash in the low addresses", but forgot to stop mapping the RAM. In real hardware, this low part of memory is remappable, both at runtime by the guest writing to a control register, and configurably as to what you get out of reset -- you can have the first flash device, or the second, or the DDR2 RAM, or the external AXI bus (which for QEMU means "nothing there"). In an ideal world we would support that remapping both at runtime and via a machine property to select the out-of-reset behaviour.
