The patch implements barrel shifter using rotate as a main primitive.
The design was optimized for Altera Cyclone III FPGA and can be reused
with other FPGA vendors and products.
The patch integrates the FPGA-optimized barrel shifter into the
Amber 23 core when it is build for Altera FPGA.
The patch reduces footprint from 1178 to 339 LEs keeping Fmax at 57-60 MHz.

The patch introduces a new configuration option `A23_RAM_REGISTER_BANK,
which controls instantiation of Amber 23 register bank.
If the option is set, a ram-based variant of the register bank is instantiated.
It can be useful in low-end FPGA designs, where flipflops and muxes are costly.
Altera Cyclone III resource utilization:
- flipflop-based register bank: 1583 combinationals + 856 registers
- ram-based register bank: 268 combinationals + 156 registers

5 bit "OH_USR" constant was used when 2 bit "USR" should be used.
Both of the constants are 0.
The fault was introduced by ram-based register bank commit.

Original Amber 23 core uses asyncronous implementation of register bank.
It leads to some problems with ram-based implementation of the register bank,
because at least Altera FPGAs uses syncronous ram blocks, so the whole address
needs to be latched.
The patch exposes non-registered versions of register select signals to the
register bank, so the bank can build address and latch it in the syncronous
ram input register.
The patch is a pre-requisite for ram-based register bank implementation on Altera FPGA.

The mlas_bug testcase tried to use stack without setting stack pointer
register, causing unpredictable behavoiur.
The patch uses an expilict stack area for the test.

Bug fix for bug reported by Botao Lee. The mode bits in the decode stage did not change immediately
after a mode switch from a teqp instruction, but 1 cycle later. This meant the wrong set of registers
was selected for writing to for 1 clock cycle. |
