Andreas Färber 1bba0dc932 Rename cpu_reset() to cpu_state_reset()
Frees the identifier cpu_reset for QOM CPUs (manual rename).

Don't hide the parameter type behind explicit casts, use static
functions with strongly typed argument to indirect.

Peter Maydell 96eacf6413 arm_boot: Pass base address of GIC CPU interface, not whole GIC
The arm_boot secondary boot loader code needs the address of
the GIC CPU interface. Obtaining this from the base address
of the private peripheral region was possible for A9 and 11MPcore,
but the A15 puts the GIC CPU interface in a different place.
So make boards pass in the GIC CPU interface address directly.

Mark Langsdorf 9d5ba9bfbc arm: add secondary cpu boot callbacks to arm_boot.c
Create two functions, write_secondary_boot() and secondary_cpu_reset_hook(),
to allow platforms more control of how secondary CPUs are brought up. The
new functions default to NULL and aren't called unless they are populated
so there are no changes to existing platform models.

The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a

Peter Maydell 756ba3b012 hw/arm_boot.c: move initrd load address up to accommodate large kernels
Newer kernels are large enough that they can overlap the address
where qemu places the initrd. Move the initrd up so that there is
enough space for the kernel again.

Unfortunately it's not possible to automatically determine the
size of the kernel if it is compressed, so this is the best we
can do.

Lars Munch e03c22a98c arm: fix arm kernel boot for non zero start addr
Booting an arm kernel has been broken a while when booting from non zero start
address. This is due to the order of events: board init loads the kernel and
sets register 15 to the start address and then qemu_system_reset reset the cpu
making register 15 zero again.

This patch fixes the usage of the register 15 start address trick in
combination with arm_load_kernel.

Aurelien Jarno 409dbce54b load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.

This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.

The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.

Adjust callers. Also use target_phys_addr_t instead of target_ulong for

Jan Kiszka 8217606e6e Introduce reset notifier order
Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.
