On Windows /dev/random does not exist, so trying to open it will fail. Replace it with rand() which is available on all supported platforms and sufficient. Fixes mkimxboot not working, as well as Rockbox Utility "crashing" (which is in fact its error handler calling exit(), thus terminating Rockbox Utility) on Windows.

This file document the format of the command file used by the elftosb tool.
By no way our tools tries to be compatible with Freescale's elftosb2.
However, our format is more subset of the general one.
The parse supports a limited form of comments: comments starting with // and ending at the end of the line.
A file first contains the list of sources:
sources
{
hw_init = "sdram_init.elf";
rockbox = "rockbox.elf";
}
It can then contain an arbitrary number of section. A section is identified by a number.
Within a section, three commands are supported: "load", "jump" and "call":
section(0x626f6f74) // hex for 'boot'
{
load hw_init;
call hw_init;
load rockbox;
jump rockbox;
}
Finally, both elftosb and sbtoelf tools use key files. A key file is a list of keys.
Each key consist is 128-bit long and is written in hexadecimal:
00000000000000000000000000000000
The parser does not handle blank line and only allows a final newline at the end of the file.
A file is allowed to contain zero (0) keys.
