* Seporate out the code used for handling the memory peripheral to peripheral/memory.c
* Mostly decouple the memory controller from the internals of the memory handling.
* Rewrite memory handling to be more linear and thus much faster.
* Issue a bus error on read/write with invalid granularity. |

When multiple interrupts were pending, e.g. TX buffer empty and RX
available, reading the UART's IIR register could potentially clear a
TX interrupt before it had been sent to the processor, thus dropping
the interrupt permanently.
Fix tested w/ both eCos and uclinux. |

There was a bug in the simulator's UART implementation that caused the
UART's LSR register to become corrupted. This was due to an
assumption that 'char' is an unsigned type, but that is not true on
all platforms.
When the char type is signed and a character is read in the range
0x80-0xff, the high bit is sign-extended into the upper bits of an
entry in the receive FIFO. When the character reaches the head of the
FIFO, the upper bits of the FIFO entry are OR'ed into the LSR, causing
the LSR to be set to 0xFF.
A simple cast fixes the problem. |
