ac71d4103e tools: mkimage: Call fclose in error path
This patch is fixing missing fclose() calls
in error patch introduced by:
"tools: mkimage: Use fstat instead of stat to avoid malicious hacks"
(sha1: ebe0f53f48)

ebe0f53f48 tools: mkimage: Use fstat instead of stat to avoid malicious hacks
The patch is fixing:
"tools: mkimage: Check if file is regular file"
(sha1: 56c7e80155)
which contains two issues reported by Coverity
Unchecked return value from stat and incorrect calling sequence where
attack can happen between calling stat and fopen.
Using pair in opposite order (fopen and fstat) is fixing this issue
because fstat is using the same file descriptor (FILE *).

Also fixing issue with:
"tools: mkimage: Add support for initialization table for Zynq and
ZynqMP" (sha1: 3b6460809c)
where file wasn't checked that it is regular file.

56c7e80155 tools: mkimage: Check if file is regular file
Current Makefile.spl passes -R parameter which is not empty
and pointing to ./ folder.
"./tools/mkimage -T zynqmpimage -R ./"" -d spl/u-boot-spl.bin
spl/boot.bin"
That's why mkimage is trying to parse ./ file and generate
register init which is wrong.
Check that passed filename is regular file. If not do not work with it.

3b6460809c tools: mkimage: Add support for initialization table for Zynq and ZynqMP
The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.

The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.

It is recommended to add reg init file to board folder.
For example:
CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int

d9b58b3031 tools: zynqmpimage: Add Xilinx ZynqMP boot header generation
Add support for the zynqmpimage to mkimage.
Only basic functionality is supported without encryption and register
initialization with one partition which is filled by U-Boot SPL.
For more detail information look at Xilinx ZynqMP TRM.
