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.

cramfsls and cramfsload are added to the command list.
A cramfs placed at 'cramfs_addr' can the be listed with 'cramfsls' and files
can be loaded with 'cramfsload'. 'cramfs_addr' is an environment variable
specifying the address the cramfs is located.
This works for powerpc and for ARM.
Use CONFIG_CMD_CRAMFS.

The env code is protected by the ENV_IS_EMBEDDED define, so attempting to
compile the code when this isn't defined is pointless. Now that the env
headers have unified around CONFIG_ENV_IS_EMBEDDED, convert the build
system to only build the env objects when this is enabled. And now that
the env code is conditionally compiled, we can drop the source code checks.
For people who want to extract the environment manually, add a new option
CONFIG_BUILD_ENVCRC that only enables the envcrc utility.

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

Legacy NAND had been scheduled for removal. Any boards that use this
were already not building in the previous release due to an #error.
The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed. There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

This patch implements simple hwconfig infrastructure: an
interface for software knobs to control a hardware.
This is very simple implementation, i.e. it is implemented
via `hwconfig' environment variable. Later we could write
some "hwconfig <enable|disable|list>" commands, ncurses
interface for Award BIOS-like interface, and frame-buffer
interface for AMI GUI[1] BIOS-like interface with mouse
support[2].
Current implementation details/limitations:
1. Doesn't support options dependencies and mutual exclusion.
We can implement this by integrating apt-get[3] into the
u-boot. But I didn't bother yet.
2. Since we don't implement hwconfig command, i.e. we're working
with the environement directly, there is no way to tell that
toggling a particular option will need a reboot to take
an effect. So, for now it's advised to always reboot the
target after modifying hwconfig variable.
3. We support hwconfig options with arguments. For example,
set hwconfig dr_usb:mode=peripheral,phy_type=ulpi
That means:
- dr_usb - enable Dual-Role USB controller;
- dr_usb:mode=peripheral - USB in Function mode;
- dr_usb:phy_type=ulpi - USB should work with ULPI PHYs;
The purpose of this simple implementation is to define some
internal API and then we can continue improving user experience
by adding more mature interface, like hwconfig command with
bells and whistles. Or not adding, if we feel that current
interface fits its needs.
[1] http://en.wikipedia.org/wiki/American_Megatrends
[2] Regarding ncurses and GUI with mouse support -- I'm just
kidding.
[3] The comment regarding apt-get is also a joke, meaning that
dependency tracking could be non-trivial. For example, for
enabling HW feature X we may need to disable Y, and turn Z
into reduced mode (like RMII-only interface for ethernet,
no MII).
It's quite trivial to implement simple cases though.

Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.
IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)
This driver support mflash IO mode.
Followings are brief descriptions about IO mode.
1. IO mode based on ATA protocol and uses some custom command. (read
confirm, write confirm)
2. IO mode uses SRAM bus interface.

According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.
This patch prepares this change and starts a 6 month transition
period as follows:
- The new "source" command has been added, which implements exactly
the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
have *not* been adapted yet; these will be renamed resp. removed in
a separate patch when the support for the "autoscr" command get's
finally dropped.

This doesn't make sense anymore since other commands (e.g. UBI) use this
infrastructure as well now. This patch separates the mtdparts commands from
the jffs2 commands making it possible to only select mtdparts when no JFFS2

Modifications to support console multiplexing. This is controlled using
CONFIG_SYS_CONSOLE_MUX in the board configuration file.
This allows a user to specify multiple console devices in the environment
with a command like this: setenv stdin serial,nc. As a result, the user can
enter text on both the serial and netconsole interfaces.
All devices - stdin, stdout and stderr - can be set in this manner.
1) common/iomux.c and include/iomux.h contain the environment setting
implementation.
2) doc/README.iomux contains a somewhat more detailed description.
3) The implementation in (1) is called from common/cmd_nvedit.c to
handle setenv and from common/console.c to handle initialization of
input/output devices at boot time.
4) common/console.c also contains the code needed to poll multiple console
devices for input and send output to all devices registered for output.
5) include/common.h includes iomux.h and common/Makefile generates iomux.o
when CONFIG_SYS_CONSOLE_MUX is set.

Several source files need to be compiled and linked when one or more
config options are selected. To allow for easy selection in the
Makefiles yet to avoild multiple compilation (which costs build time)
and especially multiple linking (which causes errors), we use
"COBJS = $(sort COBJS-y)" which eliminates duplicates.
