S390: ccw firmware: Add Makefile This patch adds a makefile, so we can build our ccw firmware. Also add the resulting binaries to .gitignore, so that nobody is annoyed they might be in the tree. Signed-off-by: Alexander Graf <agraf@suse.de>

pc-bios/s390-ccw: get LOADPARM stored in SCP Read Info Obtain the loadparm value stored in SCP Read Info by performing a SCLP Read Info request. Rename sclp-ascii.c to sclp.c to reflect the changed scope of the file.

pc-bios/s390-ccw.img: Fix build Since commit a9c87304b76d ("build-sys: fix building with make CFLAGS=.. argument") pc-bios/s390-ccw.img build might fail with --- snip --- main.o: In function `virtio_setup': qemu/pc-bios/s390-ccw/main.c:117: undefined reference to `__stack_chk_fail' --- snip --- Changing the CFLAGS to QEMU_CFLAGS does the trick. We also need to add -fno-strict-aliasing as this was filtered out.

s390/bios: Make the s390-ccw.img relocatable The current bios sits at location 0x7e00000 in the guest RAM and thus prevents loading of bigger ramdisks. By making the image relocatable we can move it to the end of the RAM so that it is getting out of the way.

rules.mak: quiet-command: Split command name and args to print The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".
