910f1ae3eb Serial: p1011: new vendor init options
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.
empty fifo on init

8627111543 IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers
As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

1a2d9b30e3 ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boards
Call watchdog_reset() upon newline. This is done here in putc
since the environment code uses a single puts() to print the complete
envrironment upon "printenv". So we can't put this watchdog call
in puts().

This is needed for boards with a very short watchdog timeout, like the
lwmon5 with a 100ms timeout. Without this patch this board resets in the
commands with long outputs, like "printenv" or "fdt print".

Note that the image size is not increased with this patch when
CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler
optimizes this additional code away.

Subsequent patch extends mpc512x serial driver to support
