2011-10-01PPC: Drop initial ESCC mappingAlexander Graf
We are mapping ESCC to a static (incorrect) address on machine init. This overlaps with our vram, rendering the screen barely usable. Since openBIOS is clever enough to map ESCC to where it needs to be, we can just drop that invalid map and everyone's happy.

2011-10-01tcg-i386: Introduce limited deposit supportJan Kiszka
x86 cannot provide an optimized generic deposit implementation. But at least for a few special cases, namely for writing bits 0..7, 8..15, and 0..15, versions using only a single instruction are feasible. Introducing such limited support improves emulating 16-bit x86 code on x86, but also rarer cases where 32-bit or 64-bit code accesses bytes or words.

2011-10-01mips_fulong2e: Reorder ISA bus and i8259 creationJan Kiszka

2011-10-01softfloat: Reinstate accidentally disabled target-specific NaN handlingPeter Maydell
Include config.h in softfloat.c, so that the target specific ifdefs in softfloat-specialize.h are evaluated correctly. This was accidentally broken in commit 789ec7ce2 when config-target.h was removed from softfloat.h, and means that most targets will have been returning the wrong results for calculations involving NaNs.

2011-10-01tcg: Add forward declarations for local functionsStefan Weil
These functions are defined in the tcg target specific file tcg-target.c. The forward declarations assert that every tcg target uses the same function prototype. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-01tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.hStefan Weil
It is now declared for all tcg targets in tcg.h, so the tcg target specific declarations are redundant. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-01tcg: Declare TCG_TARGET_REG_BITS in tcg.hStefan Weil
TCG_TARGET_REG_BITS can be determined by the compiler, so there is no need to declare it for each individual tcg target. This is especially important for new tcg targets which will be supported by the tcg interpreter. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-09-28slirp: Fix packet expirationThomas Huth
The two new variables "arp_requested" and "expiration_date" in the mbuf structure have been added after the variable-sized "m_dat_" array. The variables have to be added before the m_dat_ array instead. Without this patch, the expiration_date gets clobbered by code that accesses the m_dat_ array. I experienced this problem with the code in slirp/tftp.c: The tftp_send_data() function created a new packet with the m_get() function (which fills-in a default expiration_date value). Then the TFTP code cleared the data section of the packet, which accidentially also cleared the expiration_date. This zeroed expiration_date then finally causes the packet to be discarded during if_start(), so that TFTP packets were not transmitted anymore.

2011-09-25mips_malta: move i8259 initialization after piix4 initializationAvi Kivity
i8259 is an ISA device (or at least, depends on the ISA infrastructure to register its ioport); and the ISA bus is supplied by piix4. Later patches make this dependency explicit.

2011-09-23Makefile: Remove 'tarbin' targetPeter Maydell
Remove the 'tarbin' target -- it isn't used as part of the official QEMU release process, and it's out of date (various new bios files were never added to its list of files). It's better not to provide it at all than to have a broken makefile target we never use or test. (Creating a tarball by just pulling in binaries that have been installed directly to the system you're running the build on is a bad idea anyway: the better way to create a binary tarball would be just to install to a temporary DESTDIR and then tar up that.)
