Stefan Reinauer c0ac7e9046 * Simplify acpi_add_table
* fix some comments
* Simplify ACPI wakeup code and make it work without a memory hole
* Add resume entries to global GDT so we don't need our own for resume.
* add ECDT description to acpi.h for anyone who might need it  ;-) 
* remove rather stupid math to get the right number of MAX_ACPI_TABLES
  and just define a reasonable maximum for now.

Rudolf Marek e4be46b4c3 Following patch flushes the instruction queue when we set PE=0. This is normally
done by FAR JMP, but here it is more tricky because we run at EIP>1MB. Many
thanks to Marc and Kevin to tell me how to fix it

The trick is to use 0x66 prefix (done with ljmpl) it will allow to jump in real
mode to any EIP addresses  ;)

Rudolf Marek 33cafe5bfb Following patch implements ACPI resume support for coreboot. The hardware main
hook will come in separate patch perhaps.
