Two new options:

CONFIG_PL011_SERIAL_RLCR

Some vendor versions of PL011 serial ports (e.g. ST-Ericsson U8500)
have separate receive and transmit line control registers.  Set
this variable to initialize the extra register.

CONFIG_PL011_SERIAL_FLUSH_ON_INIT

On some platforms (e.g. U8500) U-Boot is loaded by a second stage
boot loader that has already initialized the UART.  Define this
variable to flush the UART at init time.

APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated
4/27/11) states that rev D processors may wake up with the wrong feature
set.  This patch implements the APM-proposed workaround.

To enable this patch for your board, add the appropriate define for your
CPU to your board header file.  See kilauea.h for more information.  The
following variants are supported:

#define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY

Please note that if you select the wrong define, your board will not
boot, and JTAG will be required to recover.

Tested on custom boards using:

CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY  <sfalco@harris.com>
CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY     <eibach@gdsys.de>

This patch allow to override CONFIG_SYS_TCLK from board configuration
files. This is needed for the Network Space v2 which use a non standard
core clock frequency (166MHz instead of 200MHz for a 6281 SoC).

As a possible enhancement for 6281 and 6282 devices, TCLK could be
dynamically detected by checking the Sample at Reset register bit 21.

Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available.  But this doesn't always work.

We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources.  And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.

With this change, each $(CPU)/ directory can have its own timer code.
