result in 0 being written and the upper 32bit address is omitted.

Changes in v6:
- fix oneline comment
- do not update bootargs when kernel cmdline only contains '\0'
Miao Yan (8):
x86: adjust ramdisk load address
x86: qemu: add fw_cfg support
x86: qemu: add a cpu uclass driver for qemu targ
The QEMU fw_cfg interface allows the guest to retrieve various data
information from QEMU. For example, APCI/SMBios tables, number of online
cpus, kernel data and command line, etc.
This patch adds support for QEMU fw_cfg interface.

Rename 'find_cpu_by_apid_id' to 'find_cpu_by_apic_id'. This should be a

I am afraid this still doesn't build. At least you need to make the
ACPI stuff depend on the new config option CONFIG_CMD_QEMU_FW_CFG, as
well as some tweaks in qemu.c and mp_init.c because they call
functions from the ori
implementation", there is only one way to support ACPI table
for QEMU targets which is the fw_cfg interface. Having two Kconfig options
for this purpose is not necessary any more, so this patch consolidates
the two.

This patchset cleans the QEMU fw_cfg code:
*) split qfw core and qfw command interface
*) split x86 specific operations from qfw core
*) move x86 ACPI generation code into qfw core as this can also
be used by others like ARM64
*) various cleanups

The original implementation of qfw includes several x86 specific
operations, like directly calling outb/inb and using some inline
assembly code which prevents it being ported to other architectures.
This patch adds callback functions and moves those to arch/x86/

The qfw command interface makes use of CONFIG_LOADADDR and
CONFIG_RAMDISKADDR to setup kernel. But not all boards have these macro,
which causes build problem on those platforms.
This patch fixes this issue.
