fed329aebe tools: add mksunxiboot to tools-all target
mksunxiboot is useful outside of u-boot, it is e.g. used by sunxi-tools.

a188438175 sunxi: (mksunxiboot) signature to indicate "sunxi" SPL variant
This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ

The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.

The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

e954eb8028 sunxi: move SPL-related definitions to platform-specific include
The sunxi platform currently doesn't seem to make any use of the
asm/arch-sunxi/spl.h file. This patch moves some declarations from
tools/mksunxiboot.c into it.

This enables us to reuse those definitions when extending the
sunxi board code (boards/sunxi/boards.c).

bfb05d0187 sunxi: Ensure that 'mksunxiboot' tool produces deterministic output
Currently some uninitialized padding bytes are written to the output
file, as can be confirmed with valgrind:

$ valgrind tools/mksunxiboot spl/u-boot-spl.bin spl/sunxi-spl.bin

==5581== Syscall param write(buf) points to uninitialised byte(s)
==5581==    at 0x4F0F940: __write_nocancel (in /lib64/libc-2.20.so)
==5581==    by 0x400839: main (in /tmp/u-boot/tools/mksunxiboot)
==5581==  Address 0xffeff5d3c is on thread 1's stack
==5581==  in frame #1, created by main (???)

This patch fixes the problem by clearing the whole structure instead
of just a portion of it.

1f6f61fe4c sunxi/nand: change BLOCK_SIZE in mksunxiboot to match NAND block size
This change is necessary to calculate correct checksum for NAND
boot. Works both for MMC and NAND. Without it BROM rejects boot image
as invalid (bad checksum). (Changes block size from 0x200 to 0x2000).

4ba73a5ac7 sunxi: mksunxiboot: Fix loading of files with a size which is not a multiple of 4
We should not be aligning the amount of bytes which we try to read from the
disk, this leads to trying to read more bytes then there are which fails.

file_size is already aligned to BLOCK_SIZE before being stored in
img.header.length, so there is no need for load_size at all.
