80beedcc38 s390-ccw: refactor eckd_block_num to use CHS
Add new cylinder/head/sector struct. Use it to calculate
eckd block numbers instead of a BootMapPointer (which used
eckd chs anyway).

5340eb072f s390-ccw: refactor boot map table code
Some ECKD bootmap code was using structs designed for SCSI.
Even though this works, it confuses readability. Add a new
BootMapTable struct to assist with readability in bootmap
entry code. Also:

- replace ScsiMbr in ECKD code with appropriate structs
- fix read_block messages to reflect BootMapTable
- fixup ipl_scsi to use BootMapTable (referred to as Program Table)
- defined value for maximum table entries

33dff5ff90 linux-user, m68k: select CPU according to ELF header values
M680x0 doesn't support the same set of instructions
as ColdFire, so we can't use "any" CPU type to execute
m68020 instructions.
We select CPU type ("m68040" or "any" for ColdFire)
according to the ELF header. If we can't, we
use by default the value used until now: "any".

542ca43498 linux-user: Move CPU type name selection to a function
Instead of a sequence of "#if ... #endif" move the
selection to a function in linux-user/*/target_elf.h

We can't add them in linux-user/*/target_cpu.h
because we will need to include "elf.h" to
use ELF flags with eflags, and including
"elf.h" in "target_cpu.h" introduces some
conflicts in elfload.c

5c1d3a2b6e Fix ast2500 protection register emulation
Some register blocks of the ast2500 are protected by protection key
registers which require the right magic value to be written to those
registers to allow those registers to be mutated.

Register manuals indicate that writing the correct magic value to these
registers should cause subsequent reads from those values to return 1,
and writing any other value should cause subsequent reads to return 0.

Previously, qemu implemented these registers incorrectly: the registers
were handled as simple memory, meaning that writing some value x to a
protection key register would result in subsequent reads from that
register returning the same value x. The protection was implemented by
ensuring that the current value of that register equaled the magic
value.

This modifies qemu to have the correct behaviour: attempts to write to a
ast2500 protection register results in a transition to 1 or 0 depending
on whether the written value is the correct magic. The protection logic
is updated to ensure that the value of the register is nonzero.

This bug caused deadlocks with u-boot HEAD: when u-boot is done with a
protectable register block, it attempts to lock it by writing the
bitwise inverse of the correct magic value, and then spinning forever
until the register reads as zero. Since qemu implemented writes to these
registers as ordinary memory writes, writing the inverse of the magic
value resulted in subsequent reads returning that value, leading to
u-boot spinning forever.

f6bfe45af2 hw/char/stm32f2xx_usart: fix TXE/TC bit handling
I/O currently being synchronous, there is no reason to ever clear the
SR_TXE bit. However the SR_TC bit may be cleared by software writing
to the SR register, so set it on each write.

In addition, fix the reset value of the USART status register.

1c3db49d39 raspi: Add "raspi3" machine type
This patch adds a "raspi3" machine type, which can now be selected as
the machine to run on by users via the "-M" command line option to QEMU.

The machine type does *not* ignore memory transaction failures so we
likely need to add some dummy devices later when people run something
more complicated than what I'm using for testing.

36476562d5 target/arm: Fix register definitions for VMIDR and VMPIDR
The register definitions for VMIDR and VMPIDR have separate
reginfo structs for the AArch32 and AArch64 registers. However
the 32-bit versions are wrong:
 * they use offsetof instead of offsetoflow32 to mark where
   the 32-bit value lives in the uint64_t CPU state field
 * they don't mark themselves as ARM_CP_ALIAS

In particular this means that if you try to use an Arm guest CPU
which enables EL2 on a big-endian host it will assert at reset:
 target/arm/cpu.c:114: cp_reg_check_reset: Assertion `oldvalue == newvalue' failed.

because the reset of the 32-bit register writes to the top
half of the uint64_t.

Correct the errors in the structures.

This is necessary for 'make check' to pass on big endian
systems with the 'raspi3' board enabled, which is the
first board which has an EL2-enabled-by-default CPU.
