Convert cmd_usage() calls in common to use a return value

2012-03-06T20:09:46+00:00

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

sf command: allow default bus and chip selects

2012-02-12T20:18:29+00:00

This patch allows a board configuration file to provide default bus
and chip-selects for SPI flash so that first argument to the 'sf' command
is optional.

On boards that use the mxc_spi driver and a GPIO for chip select, this allows
a much simpler command line:
	U-Boot> sf probe
instead of
	U-Boot> sf probe 0x5300

cmd_sf.c: fix printf() length modifier

2011-12-17T22:55:36+00:00

size_t is not always 'unsigned int', use corret length modifer.

This patch fixes following warning:

---8<---
cmd_sf.c: In function 'spi_flash_update_block':
cmd_sf.c:130: warning: format '%#x' expects type 'unsigend int', but argument 4 has type 'size_t'
cmd_sf.c:135: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'size_t'

cmd_sf: add "update" subcommand to do smart SPI flash update

2011-09-29T20:31:31+00:00

This adds a new SPI flash command which only rewrites blocks if the contents
need to change. This can speed up SPI flash programming when much of the
data is unchanged from what is already there.

common: fix behavior of ROUND macro when input is already rounded

2011-09-07T21:39:36+00:00

Currently when you call ROUND with a value that is already a
multiple of the second parameter it will return a value that is
one multiple larger, instead of returning the value passed in.

There are only two types of usage of ROUND currently, one in
various config files to round CONFIG_SYS_MALLOC_LEN to a multiple
of 4096 bytes.  The other in cmd_sf.c where the incorrect behavior
of ROUND is worked around be subtracting one from the length argument
before passing it to ROUND.

This patch fixes ROUND and removes the workaround from cmd_sf.  It
also results in all of the malloc pools that use ROUND to compute
their size shrinking by 4KB.

cmd_sf: use cmd_usage() in more places

2011-04-12T06:30:25+00:00

Requires a little reworking of the code flow with sub-functions, but
not a big deal.

cmd_sf: drop device status message when probing

2011-04-12T06:30:25+00:00

The common spi flash layer displays useful info when probing, so no
need for us to duplicate that.

cmd_sf: add handler for +len arg for erase command

2011-04-12T06:30:25+00:00

This patch adds [+]len handler for the erase command that will
automatically round up the requested erase length to the flash's
sector_size.

cmd_usage(): simplify return code handling

2010-07-24T18:43:57+00:00

Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.
