Note: on Nios II, we give "-G0" option to gcc and don't use gp
to access small data sections, so gp is free.
-On NDS32, the following registers are used:

- * IO port access primitives
- * -------------------------

- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place, as described by numerious
- * ARM documents:
- *
- * PCI: D0-D7 D8-D15 D16-D23 D24-D31
- * ARM: D24-D31 D16-D23 D8-D15 D0-D7
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions. Note that
- * __raw_* do not guarantee this behaviour.
- *
- * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.

-=====
-
-NDS32 is a new high-performance 32-bit RISC microprocessor core.
-
-http://www.andestech.com/
-
-AndeStar ISA
-------------
-AndeStar is a patent-pending 16-bit/32-bit mixed-length instruction set to
-achieve optimal system performance, code density, and power efficiency.
-
-It contains the following features:
- - Intermixable 32-bit and 16-bit instruction sets without the need for
- mode switch.
- - 16-bit instructions as a frequently used subset of 32-bit instructions.
- - RISC-style register-based instruction set.
- - 32 32-bit General Purpose Registers (GPR).
- - Upto 1024 User Special Registers (USR) for existing and extension
- instructions.
- - Rich load/store instructions for...
- - Single memory access with base address update.
- - Multiple aligned and unaligned memory accesses for memory copy and stack
- operations.
- - Data prefetch to improve data cache performance.
- - Non-bus locking synchronization instructions.
- - PC relative jump and PC read instructions for efficient position independent
- code.
- - Multiply-add and multiple-sub with 64-bit accumulator.
- - Instruction for efficient power management.
- - Bi-endian support.
- - Three instruction extension space for application acceleration:
- - Performance extension.
- - Andes future extensions (for floating-point, multimedia, etc.)
- - Customer extensions.
-
-AndesCore CPU
--------------
-Andes Technology has 4 families of CPU cores: N12, N10, N9, N8.
-
-For details about N12 CPU family, please check below N1213 features.
