The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

This is used by the SPI driver and ELOG.
It requires SMM TSEG and a _heap/_eheap region defined in the
linker script. The first time malloc is called in SMM the
start and end pointers to the heap region will be relocated
for the TSEG region.
Enable SPI flash and ELOG in SMM and successfully
allocate memory. The allocated addresses are verified
to be sure they are within the TSEG heap region:
smm.elf:00014000 B _eheap
smm.elf:00010000 B _heap
TSEG base is 0xad000000

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.

This patch adds code to initialize the time stamp collection
facility in coreboot. It adds a table in the CBMEM section, which
provides the base timer reading value (all other readings are
offsets of this one) and an array of timestamp id/timestamp value
pairs.
Just two values are being added now, this will have to be used
more extensively and also integrated into payloads to provide more
comprehensive boot process time measurements.
Also, since the CBMEM area could already contain a section (from the
previous run, before reset), when processing a section addition
request we should check if a section already exists and return its
address, if so.
