| 23 | /* This is a BFD backend which may be used to write PowerPCBug boot objects. |
| 24 | It may only be used for output, not input. The intention is that this may |
| 25 | be used as an output format for objcopy in order to generate raw binary |
| 26 | data. |
| 27 | |
| 28 | This is very simple. The only complication is that the real data |
| 29 | will start at some address X, and in some cases we will not want to |
| 30 | include X zeroes just to get to that point. Since the start |
| 31 | address is not meaningful for this object file format, we use it |
| 32 | instead to indicate the number of zeroes to skip at the start of |
| 33 | the file. objcopy cooperates by specially setting the start |
| 34 | address to zero by default. */ |
