|
* For testing EFI disk management we need an in memory image of
|
|
* a disk.
|
|
*
|
|
* The tool file2include converts a file to a C include. The file
|
|
* is separated into strings of 8 bytes. Only the non-zero strings
|
|
* are written to the include. The output format has been designed
|
|
* to maintain readability.
|
|
*
|
|
* As the disk image needed for testing contains mostly zeroes a high
|
|
* compression ratio can be attained.
