To: u-boot
At present two parsers have similar code to execute commands. Also
cmd_usage() is called all over the place. This series adds a single
function which processes commands called cmd_process().
This new function understands return codes, and in particular
CMD_RET_USAGE to indicate a usage error. So rather than calling
cmd_usage() themselves, the command handlers can just return this
error.
There appears to be a run_command2() which is used to run commands
with the selected parser. This series changes this in two separate
steps to just run_command(), and renames the old run_command() to
builtin_run_command(). No one should call this outside main.c since
if the hush parser is being used it is wrong to call it. The
built-in parser code could move into a separate file perhaps in a
future patch.
The overall series reduces code size on ARM by about 1KB on
my ~160KB U-Boot text region when the hush parser is used, and around
60 bytes when it isn't.
As an aside the only user of parse_line() is fsl_ddr_interactive()
which seems to have its own command line interface which operates
before DRAM is set up. Do I have this right? Is there no way this
could be done later from a normal U-Boot command?
(I have run this through MAKEALL and it seems clean)
Changes in v2:
- Fix minor errors one of which created a warning
- Squash i2c patch into the common/ patch
Changes in v3:
- Rebase to master
Changes in v4:
- Minor comment change for call to builtin_run_command()
- Add a 'repeatable' parameter to cmd_process()
- Rationalise return codes to 0, 1 and usage
- Make cmd_process() return only success (0) or failure (1)
Simon Glass (9):
Remove CMD_PXE's static on run_command()
Rename run_command() to builtin_run_command()
Rename run_command2() to run_command()
Stop using builtin_run_command()
Don't include standard parser if hush is used
Create a single cmd_call() function to handle command execution
Remove interleave of non-U-Boot code in hush
Add cmd_process() to process commands in one place
Convert cmd_usage() calls in common to use a return value

There is already a conditional on CONFIG_SYS_HUSH_PARSER, which can be removed, since it is now handled in run_command(). Do not forget to remove the hush.h include, too. Could you move this script handling into an own function into common/main.c? This way others can easily execute whole scripts without duplicating this code. I'm planning to submit support for a board which needs exactly that, so there will be at least one board which make use of this. Mike proposed source_commands() as a function name. My original patch named it run_script(). Dunno whats a better name.
