In situations like an autobuilder we are likely to not have bl31.bin
present and thus would fail to build and propagate the error upwards.
Instead, print a big warning to stderr so that human will see that
something is wrong but complete the build.

The original commit for the MCF54418TWR ColdFire development board
support defined a 'CONFIG_SYS_FAULT_ECCONFIG_SYS_NO_FLASHHO_LINK_DOWN'
which obviously has a rogue 'CONFIG_SYS_NO_FLASH' embedded in the
intended 'CONFIG_SYS_FAULT_ECHO_LINK_DOWN' define.

Rather than using CMD_JFFS2 for both the filesystem and its command, we
should have a separate option for each. This allows us to enable JFFS2
support without the command, if desired, which reduces U-Boot's size
slightly.

At present IDE support is controlled by CONFIG_CMD_IDE. Add a separate
CONFIG_IDE option so that IDE support can be enabled without requiring

Update existing users and move the ide driver into drivers/block since
