TDA4VM: TDA4VM restart remote processor issue

Hi,

When using following commands to restart the ==R5== remote processor, the Linux will get stuck in the zero out TCMs memory sometimes:

$ echo stop > state && echo start > state

static int k3_r5_rproc_prepare(struct rproc *rproc)
{
	......
	/*
	 * Zero out both TCMs unconditionally (access from v8 Arm core is not
	 * affected by ATCM & BTCM enable configuration values) so that ECC
	 * can be effective on all TCM addresses.
	 */
	dev_dbg(dev, "zeroing out ATCM memory\n");
	memset(core->mem[0].cpu_addr, 0x00, core->mem[0].size);

	dev_dbg(dev, "zeroing out BTCM memory\n");
	memset(core->mem[1].cpu_addr, 0x00, core->mem[1].size);
	......
}

Thanks 

Alex
