hw/misc/grlib_ahb_apb_pnp: Fix AHB PnP 8-bit accesses
The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:
static uint64_t grlib_ahb_pnp_read(void *opaque, hwaddr offset, unsigned size)
{
AHBPnp *ahb_pnp = GRLIB_AHB_PNP(opaque);
return ahb_pnp->regs[offset >> 2];
}
Similarly to commit
0fbe394a64 with the APB PnP registers,
set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

linux-user/mmap.c: fix integer underflow in target_mremap
Fixes: https://bugs.launchpad.net/bugs/
1876373
This code path in mmap occurs when a page size is decreased with mremap. When a section of pages is shrunk, qemu calls mmap_reserve on the pages that were released. However, it has the diff operation reversed, subtracting the larger old_size from the smaller new_size. Instead, it should be subtracting the smaller new_size from the larger old_size. You can also see in the previous line of the change that this mmap_reserve call only occurs when old_size > new_size.

hw/adc/stm32f2xx_adc: Correct memory region size and access size
The ADC region size is 256B, split as:
- [0x00 - 0x4f] defined
- [0x50 - 0xff] reserved
All registers are 32-bit (thus when the datasheet mentions the
last defined register is 0x4c, it means its address range is
0x4c .. 0x4f.
This model implementation is also 32-bit. Set MemoryRegionOps

ati-vga: check mm_index before recursive call (CVE-2020-13800)
While accessing VGA registers via ati_mm_read/write routines,
a guest may set 's->regs.mm_index' such that it leads to infinite
recursion. Check mm_index value to avoid such recursion. Log an
error message for wrong values.

target/riscv: Add the lowRISC Ibex CPU
Ibex is a small and efficient, 32-bit, in-order RISC-V core with
a 2-stage pipeline that implements the RV32IMC instruction set
architecture.

target/riscv: Don't set PMP feature in the cpu init
The PMP is enabled by default via the "pmp" property so there is no need
for us to set it in the init function. As all CPUs have PMP support just
remove the set_feature() call in the CPU init functions.

target/riscv: Disable the MMU correctly
Previously if we didn't enable the MMU it would be enabled in the
realize() function anyway. Let's ensure that if we don't want the MMU we
disable it. We also don't need to enable the MMU as it will be enabled
in realize() by default.
