Many thanks, I have added the following in coyote_init() so it should be called
during init:
---
uint8_t __iomem *f;
f = ioremap(IXP4XX_EXP_BUS_CS2_BASE_PHYS,0x1000);
if (f)
extra_uart_data[0].membase = (char *) f;
platform_add_devices(coyote_devices, ARRAY_SIZE(coyote_devices));
if (f)
iounmap(f);
----
But no success, is there anything else I can check?
Best regards
Wolf
