The lock is taken in the raw irq path and therefore a rawlock should be
used instead of a normal spinlock.
While here I drop the export symbol on that variable since there are no

IPI registers of Loongson-3 include IPI_SET, IPI_CLEAR, IPI_STATUS,
IPI_EN and IPI_MAILBOX_BUF. Each bit of IPI_STATUS indicate a type of
IPI and IPI_EN indicate whether the IPI is enabled. The sender write 1
to IPI_SET bits generate IPIs in IPI_STATUS, and receiver write 1 to
bits of IPI_CLEAR to clear IPIs. IPI_MAILBOX_BUF are used to deliver
more information about IPIs.
Why we change code in arch/mips/loongson/common/setup.c?
If without this change, when SMP configured, system cannot boot since
it hang at printk() in cgroup_init_early(). The root cause is:
console_trylock()
\-->down_trylock(&console_sem)
\-->raw_spin_unlock_irqrestore(&sem->lock, flags)
\-->_raw_spin_unlock_irqrestore()(SMP/UP have different versions)
\-->__raw_spin_unlock_irqrestore() (following is the SMP case)
\-->do_raw_spin_unlock()
\-->arch_spin_unlock()
\-->nudge_writes()
\-->mb()
\-->wbflush()
\-->__wbflush()
In previous code __wbflush() is initialized in plat_mem_setup(), but
cgroup_init_early() is called before plat_mem_setup(). Therefore, In
this patch we make changes to avoid boot failure.

Loongson doesn't support DMA address above 4GB traditionally. If memory
is more than 4GB, CONFIG_SWIOTLB and ZONE_DMA32 should be selected. In
this way, DMA pages are allocated below 4GB preferably. However, if low
memory is not enough, high pages are allocated and swiotlb is used for
bouncing.
Moreover, we provide a platform-specific dma_map_ops::set_dma_mask() to
set a device's dma_mask and coherent_dma_mask. We use these masks to
distinguishes an allocated page can be used for DMA directly, or need
swiotlb to bounce.
Recently, we found that 32-bit DMA isn't a hardware bug, but a hardware
configuration issue. So, latest firmware has enable the DMA support as
high as 40-bit. To support all-memory DMA for all devices (besides the
Loongson platform limit, there are still some devices have their own
DMA32 limit), and also to be compatible with old firmware, we keep use
swiotlb.

Loongson family machines has three types of serial port: PCI UART, LPC
UART and CPU internal UART. Loongson-2E and parts of Loongson-2F based
machines use PCI UART; most Loongson-2F based machines use LPC UART;
Loongson-2G/3A has both LPC and CPU UART but usually use CPU UART.
Port address of UARTs:
CPU UART: REG_BASE + OFFSET;
LPC UART: LIO1_BASE + OFFSET;
PCI UART: PCIIO_BASE + OFFSET.
Since LPC UART are linked in "Local Bus", both CPU UART and LPC UART
are called "CPU provided serial port".

The new UEFI-like firmware interface (LEFI, i.e. Loongson Unified
Firmware Interface) has 3 advantages:
1, Firmware export a physical memory map which is similar to X86's
E820 map, so prom_init_memory() will be more elegant that #ifdef
clauses can be removed.
2, Firmware export a pci irq routing table, we no longer need pci
irq routing fixup in kernel's code.
3, Firmware has a built-in vga bios, and its address is exported,
the linux kernel no longer need an embedded blob.
With the LEFI interface, Loongson-3A/2G and all their successors can use
a unified kernel. All Loongson-based machines support this new interface
except 2E/2F series.

the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.
The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong. Avoids the problem via telling the assembler to not use the $at

In the old source code, I have let halt and poweroff do the same action,
but in reality, they have different meanings.
As the manpage of shutdown shows:
-r Reboot after shutdown.
-H Halt action is to halt or drop into boot monitor on systems that support it.
-P Halt action is to turn off the power.
and in the real world, some machines(e.g. NAS) did not provide a power
button and the shutdown works as reset, so, we need to provide a
mechanism to let the users turn off the power safely without breaking
the system, such a mechanism is "halt", which only put the system into a
dead loop or a power-save mode and print some information to the screen
to tell the users to turn off the power safely.
$ shutdown -hH now /* loongson_halt, not turn off the power */

This patch add basic suspend support for loongson2f family machines,
loongson2f have a specific feature: when we set it's frequency to ZERO,
it will go into a wait mode, and then can be waked up by the external
interrupt. so, if we setup suitable interrupts before putting it into
wait mode, we will be able wake it up whenever we want via sending the
relative interrupts to it.
These interrupts are board-specific, Yeeloong2F use the keyboard
interrupt and SCI interrupt, but LingLoong and Fuloong2F use the
interrupts connected to the processors directly. and BTW: some old
LingLoong and FuLoong2F have no such interrupts connected, so, there is
no way to wake them up from suspend mode. and therefore, please do not
enable the kernel support for them.
The board-specific support will be added in the coming patches.
