Implement hcall based RTAS for pSeries machines On pSeries machines, operating systems can instantiate "RTAS" (Run-Time Abstraction Services), a runtime component of the firmware which implements a number of low-level, infrequently used operations. On logical partitions under a hypervisor, many of the RTAS functions require hypervisor privilege. For simplicity, therefore, hypervisor systems typically implement the in-partition RTAS as just a tiny wrapper around a hypercall which actually implements the various RTAS functions. This patch implements such a hypercall based RTAS for our emulated pSeries machine. A tiny in-partition "firmware" calls a new hypercall, which looks up available RTAS services in a table.

spapr/rtas: Force big endian compile for rtas At the moment the rtas's Makefile uses generic QEMU rules which means that when QEMU is compiled on a little endian system, the spapr-rtas.bin is compiled as little endian too which is incorrect as it is always executed in big endian mode. This enforces -mbig by defining %.o:%.S rule as spapr-rtas.bin is a standalone guest binary which should not depend on QEMU flags anyway.

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".
