Make the listed changes which are needed to re-use some definitions by the new zipl-debug(8) tool introduced by the next patch in the series: . Add definitions to boot_defs.h: . a named union disk_bloclkptr (instead of the anonymous one); . a named structure disk_program_table; . Remove a 'typedef union disk_blockptr_t' from boot/stage2.h (cleanup), use the named union in boot_defs.h instead; . Move the definition of scsi_layout types and the function get_scsi_layout() from install.c to install.h; . Move definition of PROGRAM_TABLE_BLOCK_SIZE from bootmap.c to bootmap.h Signed-off-by: Eduard Shishkin <edward6@linux.ibm.com> Reviewed-by: Stefan Haberland <sth@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
