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:
R0-R1: argument/return
R2-R5: argument
R15: temporary register for assembler
R16: trampoline register
R28: frame pointer (FP)
R29: global pointer (GP)
R30: link register (LP)
R31: stack pointer (SP)
PC: program counter (PC)
==> U-Boot will use R10 to hold a pointer to the global data
NOTE: DECLARE_GLOBAL_DATA_PTR must be used with file-global scope,
or current versions of GCC may "optimize" the code too much.
On RISC-V, the following registers are used:
x0: hard-wired zero (zero)

* ROM/FLASH is used to boot.
*
* When SW5 = "0101", MA17 = LO, the ROM is connected to BANK0,
* and the FLASH is connected to BANK1.
* When SW5 = "1010", MA17 = HI, the ROM is disabled (still at BANK0),
* and the FLASH is connected to BANK0.
* It will occur problem when doing flash probing if the flash is at
* BANK0 (0x00000000) while memory remapping was skipped.
*
* Other board like ADP-AG101P may not enable this since there is only
* a FLASH connected to bank0.

* all IO is memory mapped.
* Note that these are defined to perform little endian accesses
* only. Their primary purpose is to access PCI and ISA peripherals.
*
* 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
=====
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.
