arm: crypto: fix SHA256 shipped assembler code ...

Binutils 2.29 changed behavior of the adr instruction to always
add the thumb mode switch offset, which breaks usages where the
user is interested in the address of an internal symbol, instead
of a jump address. Binutils 3.31 fixed this by only adding the
offset when interworking is required.

As there are toolchains out there with broken binutils, it's better
to fix the code to work around the issue by not using the named
label.

ARM: i.MX27: Fix NAND boot with newer gcc ...

     6b4:	d8000800 	.word	0xd8000800

From 0x64c the code jumps to 0x69c and then back to 0x660. The jump to
0x69c triggers a icache line fetch which works fine, but then when the
function continues and the code enters the same instruction cache line
at 0x680 again then only garbage is executed, most of the time we end up
in an endless loop and the CPU jumps back somewhere at the beginning of
the function.

I have carefully added nops right before the out of line code block.
When there are enough nops to move the block to the next cache line
then the code works again.

That of course is no solution to the problem. Since I am out of ideas
what the real issue is let's just disable the icache in this function
and re-enable it in the next function. This seems to solve the problem.

net: mdio: Do not warn about invalid PHY address ...

Their child nodes are not necessarily phy nodes. For am335x devices
we get several warnings now:

miibus0: /ocp/ethernet@4a100000/mdio@4a101000 PHY address 1242566656 is too large
miibus0: /ocp/ethernet@4a100000/slave@4a100200 has invalid PHY address

miibus0: /ocp/ethernet@4a100000/cpsw-phy-sel@44e10650 PHY address 1155597904 is too large

None of the nodes is a phy node, so silence the warnings and turn them
into dev_dbg.

ARM: Multi PBL: Fix image calculation for certain toolchains ...

The current way to calculate the compressed image position works
with the OSELAS toolchains, but not with the Debian/Ubuntu toolchains.
For these toolchains &image_end_marker already returns the correct
address, adding global_variable_offset() to it is wrong.

The solution seems to be to put the image_end_marker into a different
object file so that the compiler cannot play any tricks to resolve
the address internally in the object file.
