Subject: [PATCH] remoteproc: meson-mx-ao-arc: fix a bit test
The MESON_AO_RPROC_SRAM_USABLE_BITS macro is used like this:
if (priv->sram_pa & ~MESON_AO_RPROC_SRAM_USABLE_BITS) {
dev_err(dev, "SRAM address contains unusable bits\n");
The problem is that "->sram_pa" is type phys_addr_t which is potentially
64 bits. That means the MESON_AO_RPROC_SRAM_USABLE_BITS macro needs to
be a 64 bit type as well to ensure that high 32 bits are cleared.
Fixes: 6cb58ea897dd ("remoteproc: meson-mx-ao-arc: Add a driver for the AO ARC remote procesor")
