SATA kwbimage contains offsets in block size unit, not in bytes.
Until now kwbimage expected that SATA disk always have block size of 512
bytes. But there are 4K Native SATA disks with block size of 4096 bytes.
New SATA_BLKSZ command allows to specify different block size than 512
bytes and therefore allows to generate kwbimage for disks with different
block sizes.
This change add support for generating SATA images with different block
size. Also it add support for verifying and dumping such images.
Because block size itself is not stored in SATA kwbimage, image
verification is done by checking every possible block size (it is any
power of two value between 512 and 32 kB).

Armada 385 BootROM ignores low 7 bits of headersz when parsing kwbimage
header of UART type, which effectively means that headersz is rounded down
to multiply of 128 bytes. For all other image types BootROM reads and use
all bits of headersz. Therefore fill into UART type of kwbimage v1 headersz
aligned to 128 bytes.

This change add support for mkimage's -s option to kwbimage format. It will
create an kwbimage with empty data part of image (data part would contain
only required 32-bit checksum). mkimage's -s option is indicated by skipcpy
flag and it is basically in conflict with mkimage's -d (datafile) option.
"Empty" kwbimage with no data can still contain headers. For example it can
contain binary executable header which is copied by BootROM into L2SRAM.
This is useful for example for small images which can do not require DDR
RAM and can be run in L2SRAM (which do not require any initialization).

NOR memory.

Secure boot header signature is calculated from the image header with
zeroed header checksum. Calculation is done in add_secure_header_v1()
function. So after calling this function no header member except
main_hdr->checksum can be modified. Commit 2b0980c240 ("tools: kwbimage:
Fill the real header size into the main header") broke this requirement as
final header size started to be filled into main_hdr->headersz_* members
after the add_secure_header_v1() call.
Fix this issue by following steps:
- Split header size and image data offset into two variables (headersz and
*dataoff).
- Change image_headersz_v0() and add_binary_header_v1() functions to return
real (unaligned) header size instead of image data offset.
- On every place use correct variable (headersz or *dataoff)
After these steps variable headersz is correctly filled into the
main_hdr->headersz_* members and so overwriting them in the end of the
image_create_v1() function is not needed anymore. Remove those overwriting
which effectively reverts changes in problematic commit without affecting
value in main_hdr->headersz_* members and makes secure boot header
signature valid again.

ARM executable code included in kwbimage binary header, which is not
position independent, needs to be loaded and executed by BootROM at the
correct fixed address.
Armada BootROMs load kwbimage header (in which the executable code is also
stored) at fixed address 0x40004000 or 0x40000000 which is mapped to
L2-SRAM (L2 Cache as SRAM). Address 0x40004000 is used on Armada platforms
with Sheeva CPU core (A370 and AXP) where BootROM uses MMU with 0x4000
bytes for MMU translation table. Address 0x40000000 is used on all other
platforms.
Thus the only way to specify load and execute address of this executable
code in binary kwbimage header is by filling dummy arguments into the
binary header, using the same mechanism we already have for achieving
128-bit boundary alignment on A370 and AXP SoCs.
Extend kwbimage config file parser to allow to specify load address as
part of BINARY command with syntax:
BINARY path_to_binary arg1 arg2 ... argN LOAD_ADDRESS address
If the specified load address is invalid or cannot be used, mkimage will
throw fatal error and exit. This will prevent generating kwbimage with
invalid load address for non-position independent binary code.
If no load address is specified, kwbimage will not fill any the dummy
arguments, thus it will behave the same as before this change.
