The code calculates the DDR2 SPD checksum as per JEDEC standard
No 21-C Appendix X (revision 1.2)
The code is based on the equivalent files from U-Boot version
git-a71d45d.

Being able to trace initcall is very useful when trying to
find out where startup hangs. This adds a kconfig option for
it to make it easier to access.

When using devicetrees the boardinfo (or model) can be obtained
from the devicetree. Add a function to get the boardinfo so that
we have a chance to add information from the devicetree.

ENABLE_DEVICE_NOISE is used only in two network drivers and is
otherwise unused. ENABLE_FLASH_NOISE is completely unused.
ENABLE_PARTITION_NOISE enables DEBUG in the partition command,
but this code has no debug messages at all.
Remove all this.

Barebox of_find_node_by_path requires a node to be passed as start node
to start searching. Linux OF API does not pass this node and no current
user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.

Much of the bootm code is implemented in the command itself. Move
it to a common place to be able to call it from C aswell.

Someone calling menu_show might only be interested in the entry the user
selected without having something in the action callback. Make it optional.

gotoXY has the argument order (y, x). Change this so that usage of this

More than 9 menu entries in are single menu are not aligned anymore, like
this:
8 entry8
9 entry9
10 entry10
Use %2d in the printf format specifier to align more than 9 entries.

Add mem_test routine. Useful to detect timing problems if someone
porting a new device to barebox. This test includes a data bus test,
address bus test and integrity check of memory.
This mem_test routine has as parameter start and end address of testing
space. The last parameter can skip the integrity check.

The NT disk Signature is a unique 32-bit value in the MBR allowing
to identify a MSDOS partitioned disk. The signature can be used to
specify the Linux rootfs.
This patch adds support for the NT disk Signature in the form of a
device parameter which can both be read and written.

Some drivers use blk->ops->read/write. This bypasses the caching block
layer and was never intended like this. The upper API to the block layer
is the cdev layer. This patch adds block_read and block_write functions
and uses them where appropriate.

block_read and block_write collide with a to-be-introduced
global function, so rename the file operation functions.

memory_display is a function which should generally be available.
Currently it depends on memory command support being compiled in,
so move the function to a separate file.
