If the entry is not found in the env ".flags", then look in the static

This new command supports hashing SHA1 and SHA256. It could be extended
to others such as MD5 and the CRC algorithms. The syntax is modeled on
those:
hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>]
to calculate a hash, and:
hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>]
to verify a hash.
Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and
CONFIG_SHA256 to enable SHA256.

This change adds CBFS support and some commands to use it to u-boot. These
commands are:
cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of
the ROM is an optional parameter which defaults to the standard 0xffffffff and
can be used to support multiple CBFSes in a system. The last one set up with
cbfsinit is the one that will be used.
cbfsinfo - Print information from the CBFS header.
cbfsls - Print out the size, type, and name of all the files in the current
CBFS. Recognized types are translated into symbolic names.
cbfsload - Load a file from CBFS into memory. Like the similar command for fat
filesystems, you can optionally provide a maximum size.
Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified.
The CBFS driver can also be used programmatically from within u-boot.
If u-boot needs something out of CBFS very early before the heap is
configured, it won't be able to use the normal CBFS support which caches some
information in memory it allocates from the heap. The
cbfs_file_find_uncached function searches a CBFS instance without touching
the heap.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)
We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.
We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,
we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

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.

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.

[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.

Newer Blackfin parts can an on-chip ROM that can boot LDRs over SPI flashes,
so add a new 'spibootldr' command to take advantage of it.

The kernel stores address<->symbol names in it so things can be decoded at
runtime. Do it in U-Boot, and we get nice symbol decoding when crashing.

In addition to the changes for CONFIG_ENV_IS_IN_FLASH as done in
commit afcbce07, we also need to do the same for
CONFIG_ENV_IS_IN_EEPROM and CONFIG_ENV_IS_IN_NVRAM.

Since commit a706bfc7 common/env_embedded.o and tools/envcrc were
only built when CONFIG_ENV_IS_EMBEDDED was set, but this breaks
building for many boards.
We always have to build these files when CONFIG_ENV_IS_IN_FLASH is
set.

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.

Currently the mtdparts commands are included in the jffs2 command support.
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
support is needed.

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.
