Added LoongArch barriers in barrier_spin_wait and barrier_halt_wait
functions.
Signed-off-by: Chao Li <lichao@loognson.cn>
* lib/spinlock: Add LoongArch CPU pause
Because the LoongArch haven't pause instruction, using eight nops to
replace the pause.
Signed-off-by: Chao Li <lichao@loongson.cn>
* lib/string: Make LoongArch use the string function in the file
Since LoongArch GCC doesn't have built-in string functions, use the
string function instance in the sting.c

Add LoongArch support (#410)
* lib/assert: Add LoongArch assert support
Added LoongArch break 3 assert instruction.
Signed-off-by: Chao Li <lichao@loongson.cn>
* lib/barrier: Add barrier method for LoongArch
Added LoongArch barriers in barrier_spin_wait and barrier_halt_wait
functions.
Signed-off-by: Chao Li <lichao@loognson.cn>
* lib/spinlock: Add LoongArch CPU pause
Because the LoongArch haven't pause instruction, using eight nops to
replace the pause.
Signed-off-by: Chao Li <lichao@loongson.cn>
* lib/string: Make LoongArch use the string function in the file
Since LoongArch GCC doesn't have built-in string functions, use the
string function instance in the sting.c
Signed-off-by: Chao Li <lichao@loongson.cn>
* lib/unistd: Add LoongArch CPU pause
Because the LoongArch haven't pause instruction, using eight nops to
replace the pause.

* system/acpi: Reduce the way of search RSDP for non-x86 ARCHs
Searching RSDP from legacy BIOS EDBA and reserved areas is available
only on i386 and x64.

* system/serial: Add Loongson CPU serial port support
Add the serial port address perfix of Loongson CPU and obtain serial
port clock method.

* system/smbus: Rename smbus.c to i2c_x86.c
Renamed the smbus.c to i2c_x86.c in i386 and x64 platforms.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system/smp: Add LoongArch SMP support
Added LoongArch multi-core support and a way of map to node numbers if
the NUMA is enabled.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system/timers: Add LoongArch supports
In LoongArch, there is a stable counter that is independent of other
clocks, it like the TSC in x64. Using it to count the ticks per
millisecond.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system/tsc: Add LoongArch support
Usually the frequency of stable counter is not same to CPU frequency, so
using the performance counter for the delay operations.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system/usbhcd: Add LoongArch MMIO perfix
Added LoongArch64 MMIO address perfix, use for address the PCI memory

* system/usbhcd: Add Loongson 7A2000 chipset OHCI BAR offset fix
If the BAR address is not fixed for the Loongson 7A2000 OHCI controller,
some prots will not be usable, This change currently only affects the
LoongArch platform.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system: Add the way to IO access via MMIO
Usually, it is access the IO like PCI IO via MMIO on non-X86 ARCHs, so
a method to access IO via MMIO is added.
Signed-off-by: Chao Li <lichao@loongson.cn>
* system: Add the way to access PCI memory space via MMIO
Some uniformly address ARCHs access the PCI memory depended the MMIO, so
the method to access PCI memory via MMIO is added.
