Nico Huber 425973cf42 libpayload: Always use virtual pointers in struct sysinfo_t
We had mixed virtual and physical pointers in struct sysinfo_t. Some
being virtual by accident which led to problems when we tried to
reinitialize lib_sysinfo after relocating FILO (to get intentionally
virtual pointers valid again). I guess this didn't cause much trouble
before, as lib_get_sysinfo() was always called with physical addresses
being equal to their virtual counterparts.

For FILO, two possibilities seem practical: Either, have all pointers in
struct sysinfo_t physical, so relocation doesn't hurt. Or, have all
pointers virtual and call lib_get_sysinfo() again after relocation.

This patch goes the latter way, changing the following pointers for
situations where virtual pointers differ from physical:
  .extra_version
  .build
  .compile_time
  .compile_by
  .compile_host
  .compile_domain
  .compiler
  .linker
  .assembler
  .cb_version
  .vdat_addr
  .tstamp_table
  .cbmem_cons
  .mrc_cache
We could also just correct the accidentally virtual pointers. But, IMO,
this would lower the risk of future confusion.

Note 1: Looks like .version gets never set.

Note 2: .option_table and .framebuffer were virtual pointers but treated
        like physical ones. Even in FILO, this led to no problems as
        they were set before relocation.

Nico Huber 6e711c6a97 libpayload: Add init() function to hci_t and rework uhci_reset()
uhci_reset() differs in semantics compared to the other HCI's reset()
implementations. uhci_reset() does some initialization work after a
controller reset. So move the initialization part to a new function,
uhci_reinit(), which get's exported through a new entry in hci_t:
hci_t.init().

Warning: This breaks code that relies on the current, special,
counterintuitive behaviour of uhci_reset(). If one wants a working host
controller after calling hci_t.reset(), he should call hci_t.init()
afterwards.

Duncan Laurie 11290c49b0 SMM: Restore GNVS pointer in the resume path
The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.

In order to restore this pointer it needs to be available
at resume time.  The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself.  So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.

A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.

The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

This will enable DDR3 1.35V support for memory training in
the reference code.  It requires the board to be setup for
1.35V with whatever board-specific GPIOs are available.

Vadim Bendebury 48a4a7f244 Provide MRC with a console printing callback function
Let memory initialization code use the coreboot romstage console. This
simplifies the code and makes sure that all output is available in
/sys/firmware/log.

The pei_data structure is modified to allow passing the console output
function pointer. Romstage console_tx_byte() is used for this purpose.

Bill Richardson 0a405bafc5 cros: Inform U-Boot via fake gpio when VGA Option ROM is loaded
This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.

This change sets up the communication, but doesn't act on it just yet.

Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.

ChromeOS' top of the tree u-boot expects coreboot to export information
about option ROM status (started/not started). Stumpy and Lumpy were
left behind and are not exporting this information. This CL fixes the
problem.

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

Stefan Reinauer 4221a19574 Add method for delaying adding of timestamps
In hardwaremain() we can't add timestamps before we actually
reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged
in hardwaremain() when coming out of an S3 resume.

The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c

Ronald G. Minnich 8b93059ecc Pass the CPU index as a parameter to startup.
This addition is in support of future multicore support in
coreboot. It also will allow us to remove some asssembly code.

The CPU "index" -- i.e., its order in the sequence in which
cores are brought up, NOT its APIC id -- is passed into the
secondary start. We modify the function to specify regparm(0).
We also take this opportunity to do some cleanup:
indexes become unsigned ints, not unsigned longs, for example.

Build and boot on a multicore system, with pcserial enabled.

Capture the output. Observe that the messages
Initializing CPU #0
Initializing CPU #1
Initializing CPU #2
Initializing CPU #3
appear exactly as they do prior to this change.
