memory: fix size address calculation ...

Fix size address calculation.

Global variables from <asm/sections.h> which are defined
in linker script *.lds files for end addresses has already
a +1 calculation.

For example:
stext = 0x100 with a size about 0x50 will result a etext = 0x150.
In this case a correct size calculation is (etext - stext) = 0x50.

In function 'request_sdram_region' the end address will be
calculated with (start + size - 1) which result a correct
end address of 0x149 in this example.

drivers/base: fix corrupt device tree ...

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

|    bus: add bus device
|
|    automatically add it as parent of any bus device if none already specified
|
|    we have now a nice output per bus

If for example a FATfs is mounted this nice output per bus often ends with:

>     `---- fat0
>     `---- 0

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.

filetype: Pass bufsize ...

Pass the buffer size to the file detection code. This makes sure we do not

as the magic is at byte offset 1080. Also introduce a FILE_TYPE_SAFE_BUFSIZE
define which is set to the minimum bufsize the detection code needs to detect
all known filetypes.

loadenv: allow more fine grained environment loading ...

This implements two new options for the loadenv command:

-s: removes (scrubs) old directory contents to be able to

-n: no overwrite. Do not overwrite existing files. This allows
    to keep parts of the old environment.
