Move code which reads the command block to the
new function read_cb. The patch also fixes some
endianess issues related to the command block
and moves declarations of local variables to
the beginning of the block.

There is no need for a local variable "status".
Using tx.status makes it clearer which status

Instead of magic numbers like 0x8000, symbolic names are used
for the SCB command and status bits.

There are too many configuration bits to use symbolic names
there, too. Using the BIT macro is a little help when comparing
code and documentation.

For the same reason, some other constants were replaced by
the BITS macro.

Only two boot ROM files are needed for all devices.

* Add these GPXE ROM files using new naming convention
  (as discussed on qemu-devel). Both files were created
  with http://rom-o-matic.net/, PCI vendor / device ids
  as in ROM filenames and option BANNER_TIMEOUT = 0.

* Remove old PXE ROM file for i82559er.
  It was replaced by gpxe-eepro100-80861209.rom.

* Update pc-bios/README (and sort entries).

Hello,

There is a small incoherency in curses_keys.h, which makes it fail to
emit \n when using e.g. -k fr: curses2keysym transforms \r and 0x157
into \n, but name2keysym binds \r with Return, not \n.  The patch below
fixes that.

If you make use of hw breakpoints on a 32bit x86 linux host, qemu
will segmentation fault when processing the exception.

The problem is that the value of env is stored in $ebp in the op_helper
raise_exception() function, and it can have the wrong value when
calling it from non generated code.

It is possible to work around the problem by restoring the value of
env before calling raise_exception() using a new helper function that
takes (CPUState *) as one of the arguments.

IEEE FP instructions are split up so that the rounding mode
coming from the instruction and exceptions (both masking and
delivery) are handled external to the base FP operation.
FP exceptions are properly raised for non-finite inputs to
instructions that do not indicate software completion.

A shortcut is applied if CONFIG_SOFTFLOAT_INLINE is defined
at the top of translate.c: data is loaded and stored into
FP_STATUS directly instead of using the functional interface
defined by "softfloat.h".
