Maarten ter Huurne 6edde02476 MIPS: JZ4740: setup: Autodetect physical memory.
Assume that the boot loader knows the physical memory of the system and
deduce that information from the contents of the SDRAM control register.
It is still possible to override with with the "mem=" parameter, but we
have a sensible default now.

Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should

Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.

The JZ4740 UART interface is almost 16550 compatible.
The UART module needs to be enabled by setting a bit in the FCR register
and it has support for receive timeout interrupts.  Instead of adding yet
another machine specific quirk to the 8250 serial driver we provide a
serial_out implementation which sets the required additional flags.
