47 | * The reason for having a seperate subsection .init.ramfs is to | |

49 | * | |
50 | * Reason for having .init.ramfs above .init is to make sure that the | |
51 | * binary blob is tucked away to one side, reducing the displacement | |
52 | * between .init.text and .text, avoiding any possible relocation | |
53 | * errors because of calls from .init.text to .text | |
54 | * Yes such calls do exist. e.g. | |
55 | * decompress_inflate.c:gunzip( ) -> zlib_inflate_workspace( ) | |
