The Xilinx 16550 uart core is not a standard 16550 because it uses word-based addressing rather than byte-based adressing. With additional properties it is compatible with the open firmware 'ns16550' compatible binding. This code updates the ns16550 driver to use the reg-offset property so that the Xilinx UART 16550 can be used with it. The reg-shift was already being handled.

This patch adds a new generic device tree processing function that retrieves virtual reg addresses from the device tree to the bootwrapper code. It also updates the bootwrapper code to use the new function. dt_get_virtual_reg() retrieves the virtual reg addresses from the "virtual-reg" property. If the property can't be found, it uses the "reg" property and walks the tree to translate it to absolute addresses.

dt_xlate_reg() uses the ranges properties of a node's parentage to find the absolute physical address of the node's registers. The ns16550 driver uses this when no virtual-reg property is found. Signed-off-by: NScott Wood <scottwood@freescale.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Add serial console support for non-OF systems. There is a generic serial console layer which calls a serial console driver. Included is the serial console driver for the ns16550 class of uarts. Necessary support routines are added as well. Signed-off-by: NMark A. Greer <mgreer@mvista.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>
