Richard Henderson d885bdd481 target-s390x: Tidy cpu_dump_state
The blank lines inside the single dump make it difficult for the
eye to pick out the block.  Worse, with interior newlines, but
no blank line following, the PSW line appears to belong to the
next dump block.

Richard Henderson fdefe51c28 Emit debug_insn for CPU_LOG_TB_OP_OPT as well.
For all targets that currently call tcg_gen_debug_insn_start,
add CPU_LOG_TB_OP_OPT to the condition that gates it.

This is useful for comparing optimization dumps, when the
pre-optimization dump is merely noise.

Francesco Lavra 661bafb3e1 Versatile Express: Fix NOR flash 0 address and remove flash alias
In the A series memory map (implemented in the Cortex A15 CoreTile), the
first NOR flash bank (flash 0) is mapped to address 0x08000000, while
address 0x00000000 can be configured as alias to either the first or the
second flash bank. This patch fixes the definition of flash 0 address,
and for simplicity removes the alias definition.

Meador Inge 9892cae395 hw/armv7m_nvic: Correctly register GIC region when setting up NVIC
When setting up the NVIC memory regions the memory range
0x100..0xcff is aliased to an IO memory region that belongs
to the ARM GIC.  This aliased region should be added to the
NVIC memory container, but the actual GIC IO memory region
was being added instead.  This mixup was causing the wrong
IO memory access functions to be called when accessing parts
of the NVIC memory.

Amos Kong ac05f34924 add a boot parameter to set reboot timeout
Added an option to let qemu transfer a configuration file to bios,
"etc/boot-fail-wait", which could be specified by command
    -boot reboot-timeout=T
T have a max value of 0xffff, unit is ms.

With this option, guest will wait for a given time if not find
bootabled device, then reboot. If reboot-timeout is '-1', guest
will not reboot, qemu passes '-1' to bios by default.

This feature need the new seabios's support.

Seabios pulls the value from the fwcfg "file" interface, this
interface is used because SeaBIOS needs a reliable way of
obtaining a name, value size, and value. It in no way requires
that there be a real file on the user's host machine.

Orit Wasserman 233aa5c2d1 Fix address handling in inet_nonblocking_connect
getaddrinfo can give us a list of addresses, but we only try to
connect to the first one. If that fails we never proceed to
the next one.  This is common on desktop setups that often have ipv6
configured but not actually working.

To fix this make inet_connect_nonblocking retry connection with a different
address.
callers on inet_nonblocking_connect register a callback function that will
be called when connect opertion completes, in case of failure the fd will have
a negative value
