This patch fixes a bug (?) introduced after inclusion of the new
JFFS2 code.
When not using CONFIG_JFFS2_CMDLINE, the code in cmd_jffs2.c doesn't
fill in part->sector_size (keeping it as 0), but a correct value is
needed by the code in jffs2_1pass.c. This causes all JFFS2 accesses
to be in the same place of the memory, what obviously means
impossibility to use the JFFS2 partition.
This problem is fixed in this patch by including sector size
calculation in non-CONFIG_JFFS2_CMDLINE mtdparts_init variant.

of zlib's inflate() function correctly. gunzip() is implemented

is an error.

The code in fdt_resize() to extend the fdt size to end on a page boundary
is wrong for fdt's not located at an address aligned on a page boundary.
What's even worse, the code would make actualsize shrink rather than grow
if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(),
causing fdt_add_mem_rsv to fail.
Fix it by aligning end address (blob + size) to a page boundary instead.
For aligned fdt's this is equivalent to what we had before.

If both CONFIG_ENV_SECT_SIZE and CONFIG_ENV_SIZE are defined, and the sect

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.
