Stefan Reinauer 75dbc389ec Clean up stack checking code
Several small improvements of the stack checking code:
- move the CPU0 stack check right before jumping to the payload
  and out of hardwaremain (that file is too crowded anyways)
- fix prototype in lib.h
- print size of used stack
- use checkstack function both on CPU0 and CPU1-x
- print amount of stack used per core

Ronald G. Minnich 9764d4c690 Implement stack overflow checking for the BSP
Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.

Break the stack checking out into a separate function, which
we will later use for the APs.

CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000

Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

Stefan Reinauer c44de4999f selfboot: drop dead code
As a left over from elfboot times, selfboot keeps the segments to
load in the order in which they appeared in the original file as
well as in the order they will later appear in memory. This is not
needed in selfboot, so drop the code and structure members that handle
the in-file order.

valid_area will accept a region as valid for the payload if only a part
of coreboot fits in that region. This means if a payload reaches into a
neighboring RESERVED region, coreboot would not care and happily
overwrite that region, as long as the payload also writes to some RAM.

Zheng Bao e6ad7fa4a6 If the coreboot and filo overlap, it will "slice off" a piece at the
"beginning" or "end". In the beginning case, a new segment is inserted
before the current one.  But the ptr will move forward and doesn't
seem to have any other chance to process the "new" segment.

                ptr ---------+     move --->
                             |
                             V
        +--------+       +--------+
        |        |       |        |
        |  new   | <---> |current | <---> .....
        |        |       |        |
        +--------+       +--------+

Now we change the ptr to the previous one and restart the loop. The
new and current segment will both be processed. Even if the current
segment is done twice, no new segment will come up and ptr will move
forward as we expect.

      +----------------ptr      move --->
      |
      V
 +--------+        +--------+       +--------+
 |        |        |        |       |        |
 |  prev  | <--->  |  new   | <---> |current | <---> .....
 |        |        |        |       |        |

Patrick Georgi 369bc7882a Move decompression further down the code flow, so that - where
possible - code is decompressed directly to the right place
(instead of copying around, as before).

The downside of this approach is that it's not possible (without API
changes to the decompressors) to put partial segments into bounce
buffers. So if a segment collides with coreboot _and_ is compressed,
it's bounced entirely.
But, as this only brings back the copy we already had before, the new
worst case is better than the average before.

It also fixes handling of compressed segments.
