+ARM M: Systick first wrap delayed (qemu-timers/icount prb?)
+
+When running this kind of code with qemu:
+
+static void SysTickISR(void)
+{
+	printf("SysTick\n");
+}
+
+void main()
+{
+	volatile int i, j;
+	printf("setup timer\n");
+	*(uint32_t*) 0xE000E014 = 0x8FFFFF; //reload value
+	*(uint32_t*) 0xE000E018 = 0;        //force reload
+	*(uint32_t*) 0xE000E010 = 7;        //cpu clk + ISR + enable 
+
+	for (j = 0; j < 0x100; j++) {
+		for (i = 0; i < 0x100000; i++)
+			;
+		printf("cnt %08x  -- %8x\n", *(uint32_t*) 0xE000E018, *(uint32_t*)0xE000E010);
+	}
+}
+
+I get the following output (comments added after '#'):

+Not working with git tag 2.10.0 (almost same config)
+
+Working with stock qemu-arm 2.5.0 from Ubuntu 16.04.
+
+I started investigating, though I am not familiar with qemu code and I could see that the execution is not geting out of qemu_tcg_rr_cpu_thread_fn() 'while' loop and timers are not triggered because the values in cpu->icount_extra or cpu->icount_budget are not to modified accordingly after the timer is set (host side) when the systick register is written (target side).
