Subject: [PATCH v2 00/35] Andes(nds32) Linux Kernel Port
This is the 2nd version patchset to add the Linux kernel port for Andes(nds32)
processors. Almost all of the feedback from v1 patchseries has been addressed.
Thanks to everyone who provided feedback on the previous version.
This patchset adds core architecture support to Linux for Andestech's
N13, N15, D15, N10, D10 processor cores.
Based on the 16/32-bit AndeStar RISC-like architecture, we designed the
configurable AndesCore series of embedded processor families. AndesCores
range from highly performance-efficient small-footprint cores for
microcontrollers and deeply-embedded applications to 1GHz+ cores running
Linux, covering general-purpose N-series cores for a wide range of computing
need, DSP-capable D-series cores for digital signal control,
instruction-extensible E-series cores for application-specific acceleration,
and secure S-series cores for best protection of the most valuable.
The patches are based on v4.14-rc8, and can also be found in the
following git tree:
https://github.com/andestech/linux.git nds32-4.14-rc8-v2
The build script and toolchain repositories are able to be found here:
https://github.com/andestech/build_script.git
Freely available instruction set and architecture overview documents can
be found on the following page:
http://www.andestech.com/product.php?cls=9
Vincent Ren-Wei Chen and I will maintain this port. Thanks to everyone who
helped us and contributed to it. :) Any feedback is welcome.
Changes in v2:
- Set GENERIC_CALIBRATE_DELAY default n
- Add earlycon support
- Remove earlyprintk
- Add CPU_BIG_ENDIAN, CPU_LITTLE_ENDIAN support
- Refine unalignment access exception handler
- Add VMSPLIT support
- Use only one defconfig
- Change interrupt-cells from 2 to 1
- Refine andestech cpu names in bindings/nds32/cpus.txt
- Get clock frequency in dts because fpga bitmap doesn't include this feature
- Update MAINTAINERS for bindings
- Remove unused configs in Kconfig
- Refine device tree scripts
- Refine coding style
- Use generic ioremap_nocache
- Remove L2CC_PA_BASE define and its codes in head.S. It will be moved to bootloader.
- Set PHYS_OFFSET to 0x0 instead of CONFIG_MEMORY_START
- Remove unused macros
- Simplify cpu_cache_* API
- Change __asm__ __volatile__ to asm volatile
- Refine uaccess.h
- Remove unused/deprecated syscall
- Use generic posix_types.h
- Remove arch_trace_hardirqs_on/arch_trace_hardirqs_off
- Fix bug of restart syscall
- Refine syscall implementations
- Use IS_ENABLED to replace ifdef as possible
- Remove device_initcall(nds32_device_probe)
- Refine vdso implementations
- Refine copy_from_user()/copy_to_user()/clear_user()/get_user()/memmove()/memcpy()
- Refine ioremap.c
- Refine irq-ativic32.c
- Fix a bug of earlycon.c
- Export ioremap_nocache/ioremap_uc/ioremap_wc/ioremap_wt
- Add atcpit100 driver
