Michal Simek 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"

Michal Simek 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.

Mike Looijmans 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

Nathan Rossi 66eef1e780 tools: zynqimage: Add Xilinx Zynq boot header generation to mkimage
As with other platforms vendors love to create their own boot header
formats. Xilinx is no different and for the Zynq platform/SoC there
exists the "boot.bin" which is read by the platforms bootrom. This
format is described to a useful extent within the Xilinx Zynq TRM.

This implementation adds support for the 'zynqimage' to mkimage. The
implementation only considers the most common boot header which is
un-encrypted and packed directly after the boot header itself (no
XIP, etc.). However this implementation does take into consideration the
other fields of the header for image dumping use cases (vector table and
register initialization).
