Add support for ARM BE8 userspace binaries. i.e. big-endian data and little-endian code. In principle LE8 mode is also possible, but AFAIK has never actually been implemented/used. System emulation doesn't have any useable big-endian board models, but should in principle work once you fix that. Dynamic endianness switching requires messing with data accesses, preferably with TCG cooperation, and is orthogonal to BE8 support. Signed-off-by: NPaul Brook <paul@codesourcery.com> [PMM: various changes, mostly as per my suggestions in code review: * rebase * use EF_ defines rather than hardcoded constants * make bswap_code a bool for future VMSTATE macro compatibility * update comment in cpu.h about TB flags bit field usage * factor out load-code-and-swap into arm_ld*_code functions and get_user_code* macros * fix stray trailing space at end of line * added braces in disas.c to satisfy checkpatch ] Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Signed-off-by: NRiku Voipio <riku.voipio@linaro.org>

The list of ARM syscall numbers was missing the entry for ppoll, which meant we were accidentally not providing it.

When running 32-on-64 bit guests, we should always reserve as much virtual memory as we possibly can for the guest process, so it can never overlap with QEMU address space. Fortunately we already have the infrastructure for that. All that's missing is some sane default value to also make use of it!

When running with -R (RESERVED_VA > 0) all guest virtual addresses are within the [0..RESERVED_VA] range. Reflect this with g2h_valid() too so we can safely check for boundaries of our guest address space.

A strong limitation of QOM right now is that unconverted ports (e.g. all...) do not give a canonical path to devices that are part of the board. This in turn makes it impossible to replace PROP_PTR with a QOM link for example.

We want the composition tree to to be in order by the time we call qdev_init, so that a single set of the toplevel realize property can propagate all the way down the composition tree. This is not the case so far. Unfortunately, this is incompatible with calling qdev_init in the constructor wrappers for devices, so for now we need to unattach some devices that are created through those wrappers. This will be fixed by removing qdev_init and instead setting the toplevel realize property after machine init.

We never actually clear the TEMT (transmit sending register empty) flag when populating the TSR. We set the flag, but since it's never cleared, setting it is sort of pointless.. I found this with a unit test case. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

I'm not sure if the retry logic has ever worked when not using FIFO mode. I found this while writing a test case although code inspection confirms it is definitely broken. The TSR retry logic will never actually happen because it is guarded by an 'if (s->tsr_rety > 0)' but this is the only place that can ever make the variable greater than zero. That effectively makes the retry logic an 'if (0)'. I believe this is a typo and the intention was >= 0. Once this is fixed though, I see double transmits with my test case. This is because in the non FIFO case, serial_xmit may get invoked while LSR.THRE is still high because the character was processed but the retransmit timer was still active. We can handle this by simply checking for LSR.THRE and returning early. It's possible that the FIFO paths also need some attention.
