ZynqImageHeaderStructure does not match with the datafields in the manual

Hello,
according to
https://www.xilinx.com/support/documentation/sw_manuals/xilinx2018_2/ug1283-bootgen-user-guide.pdf
Page 16, Table 4: Zynq-7000 SoC Device Image Header,
the content of the structure should be

0x0: next image header
0x4: corresponding partition header
0x8: Reserved
0xC: Partition Count length (number of partitions)
0x10..N Image name
N: String terminator
N+4 Reserved

However, in https://github.com/Xilinx/bootgen/blob/d000746f9621000042d9469686ee867d73321c17/imageheadertable-zynq.h
ZynqImageHeaderStructure is defined as:

0x0: next image header
0x4: corresponding partition header
0x8: dataSectionCount
0xC: imageNameLength
0x10..N Image name

So the imageNameLength seems to be wrong. Moreover, when reading the data field imageNameLength, I always get a 1, even if there is valid name with > 10 chars present. So this indeed looks much more like being the number of partitions, not the name length.

Read page 16, Table 4 of the linked UG1283 manual and compare it with ZynqImageHeaderStructure in imageheadertable-zynq.h. Confirm the field meanings and offsets, then update the structure and verify that the partition count and image name data match the documented layout.
