This introduces the part start and part size sub-commands. The purpose of these
is to store the start block and size of a partition in a variable, given the
device and partition number.

This allows reading raw data that fits a single partition more easily.
For instance, this could be used to figure out the start block and size of a
kernel partition when a partition table is present, given the partition number.

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read
U-Boot from raw memory. Thus, there is no reason to provide a sector or
partition for raw mode. This allows this behaviour and still provides a robust
fallback mechanism in case provisions for both modes are defined.

When building tools-only (or env) we need to be sure that we do use
<linux/kconfig.h> and do not use <generated/autoconf.h>.  This will fix
problems such as running 'make defconfig' or 'make sandbox_config' and
then 'make tools-only'.

Based on the responses below to the thread add linux/kconfig.h higher in
the includes and drop the now unneeded autoconf.h lower down to ensure
the default environment is included correctly

To make this more flexible, lets add make those 2 parameters
configurable via the cmdline. Here the new parameters:

-q <req-delay>:  use specific request-delay
-s <resp-timeo>: use specific response-timeout

For the Marvell DB-88F6820 these values are known to work:

One board:
-q 2 -s 1

2nd board:
-q 5 -s 5

So this seems to be even board specific. But with this patch now
