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.

MMC: add erase function to both mmc and sd

2011-07-16T01:29:17+00:00

Erase is a very basic function since the begin of sd specification is
announced. Although we could write a bulk of full 0xff memory to the
range to take place of erase, it is more convenient and safe to
implement the erase function itself.

mmc: enable partition switch function for emmc

2011-05-18T19:37:03+00:00

For emmc, it may have up to 7 partitions: two boot partitions, one
user partition, one RPMB partition and four general purpose partitions.
(Refer to JESD84-A44.pdf/page 154)

As bootloader may need to read out or reflashing images on those

different partitions, it is better to enable the partition switch with
console command support.

Also for partition would be restore to user partition(part 0) when CMD0
is used, so change mmc_init routine to perform normal initialization
only once for each slot, unless use the rescan command to force init
again.

cmd_mmc: use common usage function

2010-09-21T19:37:08+00:00

Rather than using a custom "Usage:", use the common cmd_usage() function,
and tail into it now that it returns 1 for us.
