Collect modules in a linked list and implement lsmod.

Collect all commands in a linked list. This makes it easier to handle ...

dynamically registered commands.

add module.o and module.lds to Makefile

Use Linux Kernel list implementation for console devices instead ...

of homegrown list.

Fix use of unitialized Variable. Why didn't this come up earlier???

__u_boot__symtab -> __usymtab

export symbols

add dependency to include/uboot_default_env.h for startup.c

add module linker script

module.c: Due to an extra linking step we do not have u_boot_cmd_* ...

sections anymore. We now have u_boot_cmd and can properly handle
more than one command in a module

add missing include

export functions

CONFIG_MODULE -> CONFIG_MODULES

hush.c: split high-density "if(x) something"; into two lines

hush.c: get_local_var() is used only once, put it into the function ...

where it is called

fix indention in hush.c

remove comment about glob in hush.c. We do not use glob

fix indention in hush.c

fix indention in hush.c

fix indention in hush.c

Export symbols printf and the ones needed for getopt

add help texts for KALLSYMS and MODULE

Resolve the symbols using an extra section and only resolve explicitly ...

exported symbols. Using kallsyms for this purpose doesn't do it because
kallsyms do not resolve variables. Also the symbol table gets quite
big using kallsyms.

add missing whitespace in printf output

Add register_command() to register a command in runtime. This ...

is only needed when modules are enabled, so the change is inside
"#ifdef CONFIG_MODULE"

make simple parser compile again

Add module handling (mostly copied from Linux kernel and stripped down ...

for U-Boot)

add kallsyms from linux kernel

Extend 'export' command to take the form export a=b

declare lots of functions static
