7a7f91f61b ok we now get so that the uart init's and we can print. We 
cannot set baud rate as they did in 6.4, this hoses things and
we loose our 38400 default term.

We now lock somewhere in tcinit.

8fae280afb With this commit our friend RMI will now compile. I have 
not tested it and the chances of it running yet are about
ZERO.. but it will now compile. The hard part now begins,
 making it run ;-)

aa40b001c3 This is a temporary hack so we can get RMI to re-use the 
ns8250 code. We will need to think of a better way for
code reuse for this (see sys/mips/rmi/uart_cpu_mips_xlr.c for where
it is used)

3c2330f2e4 Parse and save the command line passed in from RedBoot (exec -c "xxx") and also 
the board specific environment variables.

This is not ar71xx specific and should be shared better.

ed7d70c2bb Allow a scratch buffer to be set in order to be able to use setenv() while 
booting, before dynamic kenv is running. A few platforms implement their own
scratch+sprintf handling to save data from the boot environment.

1453f4e112 - Fix busdma sync: dcache invalidation operates on cache line aligned 
addresses and could modify areas of memory that share the same cache
  line at the beginning and at the ending of the buffer. In order to
  prevent a data loss we save these chunks in temporary buffer before
  invalidation and restore them afer it.

c64429e2b5 If the FIS entry is smaller than the sector size then set it as hot so g_slice 
calls us to fix it, we then issue a read for a full sector and then copy in/out
the payload. This will happen if Redboot is compiled with
CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG.

abd74e0c14 Remove redundant instructions from tlb.S 
The "_MTC0 v0, COP_0_TLB_HI" is actually incorrect because v0 has not been
initialized at that point. It worked correctly because we subsequently
did the right thing and initialized TLB_HI correctly.

The "li v0, MIPS_KSEG0_START" is redundant because we do exactly the same
thing 2 instructions down.

24c8d4c173 Get rid of the hardcoded constants to define cacheable memory: 
SDRAM_ADDR_START, SDRAM_ADDR_END and SDRAM_MEM_SIZE

Instead we now keep a copy of the memory regions enumerated by
platform-specific code and use that to determine whether an address
is cacheable or not.

55173ef287 - Commit missing part of "bt" fix: store PC register in pcb_context struct 
in cpu_switch and use it in stack_trace function later. pcb_regs contains
    state of the process stored by exception handler and therefor is not
    valid for sleeping processes.

d428afbbbb The default KERNLOADADDR does not work on MALTA hardware. On my platform the 
"First free SDRAM address" reported by YAMON is 0x800b6e61.

So use a conservative KERNLOADADDR of 0x80100000.

4e6df32763 - Use PC/RA/SP values as arguments for stacktrace_subr instead of trapframe. 
Context info could be obtained from other sources (see below) no only from
    td_pcb field
- Do not show a0..a3 values unless they're obtained from the stack. These
    are only confirmed values.
- Fix bt command in DDB. Previous implementation used thread's trapframe
    structure as a source info for trace unwinding, but this structure
    is filled only when exception occurs. Valid register values for sleeping
    processes are in pcb_context array. For curthread use pc/sp/ra for current
    frame

257c916acf More initial RMI files. Note that these so far do NOT 
compile and many of them may disappear. For example
the xlr_boot1_console.c is old code that is ifdef'd out.
I will clean these sorts of things up as I make progress
on the port. So far the only thing I have I think straightened
out is the bits around the interupt handling... and hey that
may be broke ;-)
