57e15e609e vbe: remove the necessity for a global vbe_mode_info_valid()
There's no users of vbe_mode_info_valid() aside from the local
compilation units. Remove the declaration and make the function
static to the current global implementers.

bdb5c8feae coreboot_tables: specify clear interface for lb_framebuffer()
For some reason the "interface" for adding framebuffer information
is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some
macro if CONFIG_* for good measure.

Move the fill_lb_framebuffer() declaration to coreboot_tables.h and
provide a comment about how it should be used. Also, now that
there's no need for the notion of a global vbe_mode_info_valid()
remove it from the conditional call path of fill_lb_framebuffer().

a7dd645594 CBMEM: Add config CBMEM_TOP_BACKUP
AGESA and binaryPI boards have no easy way to determine correct
cbmem_top() location early enough when GFXUMA is enabled, so they
will use these functions with EARLY_CBMEM_INIT as well.

At the end of AmdInitPost() the decisions of UMA base and size
have not been written to hardware yet. The decisions are stored
inside AGESA heap object we cannot locate from coreboot proper
until after AmdInitEnv().

Modify code such that weak backup functions are only defined
for LATE_CBMEM_INIT; they are somewhat troublesome to handle.

de705fa1f4 drivers/spi: Re-factor spi_crop_chunk
spi_crop_chunk is a property of the SPI controller since it depends
upon the maximum transfer size that is supported by the
controller. Also, it is possible to implement this within spi-generic
layer by obtaining following parameters from the controller:

1. max_xfer_size: Maximum transfer size supported by the controller
(Size of 0 indicates invalid size, and unlimited transfer size is
indicated by UINT32_MAX.)

2. deduct_cmd_len: Whether cmd_len needs to be deducted from the
max_xfer_size to determine max data size that can be
transferred. (This is used by the amd boards.)

b9126fe46c cr50: check if the new image needs to be enabled and act on it
The AP sends the Cr50 a request to enable the new firmware image. If
the new Cr50 image was found and enabled, the AP expects the Cr50 to
reset the device in 1 second.

While waiting for the Cr50 to reset, the AP logs a newly defined event
and optionally shuts down the system. By default the x86 systems power
off as shutting those systems down is not board specific.

BRANCH=gru,reef
BUG=b:35580805
TEST=built a reef image, observed that in case cr50 image is updated,
     after the next reboot the AP stops booting before loading depthcharge,
     reports upcoming reset and waits for it.

e4d7abc0d4 lib: provide clearer devicetree semantics
The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:

1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST

The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

eef40eb2a9 drivers/storage: Add SD/MMC/eMMC driver based upon depthcharge
The SD/MMC support is broken into several pieces.  There are three main
data structures:
* sdhci_ctrlr - This is SDHCI controller specific and defined in
  include/device/sdhci.h
* sd_mmc_ctrlr - This contains generic controller management data and
  defined in include/device/sd_mmc_ctrlr.h
* storage_media - This contains the flash storage device management data
  and is defined in include/device/storage.h

The SD/MMC driver consists of several components:
* SDHCI controller code
  * bouncebuf.c
  * bouncebuf.h
  * pci_sdhci.c
  * sdhci.c
  * sdhci.h
  * sdhci_adma.c
  * sdhci_display.c
* Flash storage device support
  * mmc.c
  * mmc.h
  * sd.c
  * sd_mmc.c
  * sd_mmc.h
  * storage.c
  * storage.h
  * storage_erase.c
  * storage_write.c

Kconfig values enable various portions of the controller and storage
drivers to be built to reduce the overall size of what is included in
the final image.

Full read/write/erase operations are provided for those platforms which
want to take advantage.  It is also possible to build the driver to
perform initialization only.  By default, this driver is not included in
any platform, platforms must specifically select DRIVERS_STORAGE to add
the SD/MMC support.

After this patch is reviewed and merged, there are some additional
patches:
* Common CAR storage area - Use a predefined region of CAR to pass data
  structures between bootblock through to romstage.  This allows early
  stages to preform the SD/MMC device initialization and later stages
  to use the SD/MMC device without further initialization.  The example
  code initializes the SD/MMC device in bootblock and uses the SD/MMC
  device in romstage without further initialization.
* CBMEM ID - Add a CBMEM ID value for the data structures so that they
  may be passed from romstage to ramstage and eventually the payload.
  The example uses the SD/MMC device in ramstage without further
  initialization.
* Move the SD/MMC driver into commonlib
* Have libpayload build the SD/MMC driver from commonlib.  The intent
  is to pass the controller state to libpayload so that the SD/MMC
  device can be used without further initialization.
* On some platforms, have depthcharge use the commonlib SD/MMC driver


History:

Copy the SD/MMC driver from depthcharge revision eb583fa8 into coreboot
and make the following changes:

* Removed #include "config.h" from mmc.c, allow the lint tests to pass.
* Move include files from drivers/storage into include/device.

* Rename the macros mmc_debug, mmc_trace and mmc_error to sd_mmc_*.
* Replace printf with sd_mmc_error.
* Add sdhc_debug, sdhc_trace and sd_error macros.
* Add Kconfig values to enable storage device debugging and tracing.
* Add tracing and debug support to the SDHCI driver.
* Allow SOC to override more controller features.
* Split out ADMA support.

* Statically allocate MmcMedia.
* Replace the SdhciHost structure with the MmcCtrlr structure.
* Split the code to support other SD/MMC controllers.
* Split out erase and write support.
* Update the code to be more consistent with the coreboot coding style.
* Only expose calling APIs.
* Divide up mmc.c into 4 modules: MMC, SD, storage card, common code.
* Update debug and error messages.
* Add partition support.
* Display clock frequencies once in MHz.
* Remove mmc_send_cmd, use ctrlr->send_cmd instead.
* Handle error from sd_send_op_cond.
* Allow mainboard to control delays around CMD 0.
* Support command logging.
* Mainboard may set delay after SD/MMC command.
* Display serial number with sd_mmc_trace.
* Remove cmd set parameter from mmc_switch.
* Display errors for timeout and comm errors.
* Add LED support.
* Move 64bit DMA flag into ctrlr->caps.
* Rework PIO transfer routine.
* Add HS200 bus tuning.
* Add support for HS400.
* Use same format for HS400, HS200 and HS52.
* Reduce storage_media structure size
* Add routine to update code pointers
* Add display of storage setup
* Display controller setup

image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

73d042bd90 vboot: Disallow separate verstage after romstage, try to clarify logic
No board has ever tried to combine CONFIG_SEPARATE_VERSTAGE with
CONFIG_VBOOT_STARTS_IN_ROMSTAGE. There are probably many reasons why
this wouldn't work (e.g. x86 CAR migration logic currently always
assumes verstage code to run pre-migration). It would also not really
make sense: the reason we use separate verstages is to decrease
bootblock size (mitigating the boot speed cost of slow boot ROM SPI
drivers) and to allow the SRAM-saving RETURN_FROM_VERSTAGE trick,
neither of which would apply to the after-romstage case. It is better to
just forbid that case explicitly and give programmers more guarantees
about what the verstage is (e.g. now the assumption that it runs pre-RAM
is always valid).

Since Kconfig dependencies aren't always guaranteed in the face of
'select' statements, also add some explicit compile-time assertions to
the vboot code. We can simplify some of the loader logic which now no
longer needs to provide for the forbidden case. In addition, also try to
make some of the loader logic more readable by writing it in a more
functional style that allows us to put more assertions about which cases
should be unreachable in there, which will hopefully make it more robust
and fail-fast with future changes (e.g. addition of new stages).

021ec2819b cr50: add unmarshaling of vendor commands and process 'enable_update'
The upcoming Cr50 firmware changes will require the AP to enable the
previously downloaded Cr50 firmware update(s).

A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for
that. The command accepts one parameter - a timeout value in range of
0 to 1000 ms.

When processing the command the Cr50 checks if the alternative RO or
RW image(s) need to be enabled, and if so - enables them and returns
to the host the number of enabled headers.

If the vendor command requested a non-zero timeout, the Cr50 starts
a timer to trigger system reboot after the requested timeout expires.

The host acts on the number of enabled headers - if the number is
nonzero, the host prepares the device to be reset and waits for the
Cr50 to reboot the device after timeout expires.

This patch also adds more formal vendor command
marshaling/unmarshaling to make future additions easier.

BUG=b:35580805
TEST=with the actual user of this code in the next patch verified that
