Subject: [PATCH-for-5.0 3/7] hw/misc/grlib_ahb_apb_pnp: Fix AHB PnP 8-bit accesses
Date: Tue, 31 Mar 2020 12:50:44 +0200 [thread overview]
Message-ID: <20200331105048.27989-4-f4bug@amsat.org> (raw)
In-Reply-To: <20200331105048.27989-1-f4bug@amsat.org>
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.
