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).

When mkimage was instructed to skip datafile via option -s then do not try
to validate or open datafile as it does not have to exist or to be
specified via -d option.
This change allows to use -s option for skipping datafile when -d option
for datafile was not specified.

When asking mkimage to create a new image file and option -d is not
specified then mkimage show human unfriendly error message:
mkimage: Can't open (null): Bad address
Without debugger it is hard to debug what is the issue. Function open() is
being called with file name set to NULL. So add a check for this and if it
happens then show human readable message that option -d was not specified.

Marvell BootROM can execute SPI images directly from NOR (either SPI/serial
or parallel) without copying them to DDR RAM. This is know at XIP - execute
in place. To achieve that, destination address in kwbimage must be set to
0xFFFFFFFF and execute address to the offset in bytes from the beginning of
NOR memory.
Kirkwood and Dove which use kwbimage v0 format and have SPI address space
mapped to physical memory at 0xE8000000-0xEFFFFFFF by BootROM.
Armada SoCs use kwbimage v1 format and have SPI address space mapped to
physical memory at 0xD4000000-0xD7FFFFFF and Device bus address space (used
for parallel NOR) at 0xD8000000-0xDFFFFFFF.

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.

Secure boot data image signature is calculated from the data image without
trailing 4-bit checksum. Commit 37cb9c15d7 ("tools: kwbimage: Simplify
aligning and calculating checksum") unintentionally broke this calculation
when it increased payloadsz variable by 4 bytes which was propagated also
into the add_secure_header_v1() function. Fix this issue by decreasing size
of buffer by 4 bytes from which is calculated secure boot data image
signature.

kwbimage nandblocksize field is in 64 kB unit, but NAND_BLKSZ command
expects it in bytes. So do required unit conversion.
Also zero value in nandblocksize field has special meaning. When this field
is set to zero, the default block size is used. This default size is
defined by the NAND flash page size (16 KB for a 512B page or small page
NAND and 64 KB for a large page NAND flash).

Value 0x0 for NAND_BADBLK_LOCATION/nandbadblklocation means that BBI is on
the first or second page and value 0x1 means that BBI is on the last page.
This indicates also NAND Flash Technology, value 0x0 is SLC NAND and value
0x1 is MLC NAND.
Therefore we need to dump NAND_BADBLK_LOCATION also when it is zero.
Note that in v0 images, nandbadblklocation field overlaps with ddrinitdelay
field in one union. ddrinitdelay is used in Kirkwood and nandbadblklocation
is used in Dove. For Dove images is_v0_ext should be set, so use it to
distinguish if nandbadblklocation is available or not. In v1 images there
is always nandbadblklocation field.

Some NOR images may be execute-in-place and do not contain DDR init code in
its kwbimage header. Such images cannot be booted over UART as BootROM
loads them to RAM. Add check that kwbimage contains DDR init code in its
header (either as binary code header or as the simple register-value set).
In some cases it is possible to load very small image into L2SRAM and when
DDR init code is not required. So check for L2SRAM load address and skip
DDR init code check in this case.

The 32-bit data checksum in UART image is not checked by the BootROM and
also Marvell tools do not generate it.
So if data checksum stored in UART image does not match calculated checksum
from the image then treat those checksum bytes as part of the executable
image code (and not as the checksum) and for compatibility with the rest of
the code manually insert data checksum into the in-memory image after the
executable code, without overwriting it.
This should allow to boot UART images generated by Marvell tools.
