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.

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

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

The Cr50 TPM uses an IRQ to provide a "status" signal used for hand-shaking
the reception of commands. Real IRQs are not supported in firmware,
however firmware can still poll interrupt status registers for the same
effect.
Commit 94cc485338 ("drivers/i2c/tpm/cr50: Support interrupts for status")
added support for the Cr50 driver on X86 platforms to use a KConfig file
to supply an IRQ which it would poll using acpi_get_gpe. If the IRQ is
not supplied, the Cr50 driver inserts a 20 ms wait.
Unfortunately this doesn't work so well when using the i2c connected Cr50
on ARM platforms. Luckily, a more generic implementation to allow a
mainboard to supply a Cr50 IRQ status polling function was solved for SPI
connected Cr50s by commit 19e3d335bd ("drivers/spi/tpm: using tpm irq to
sync tpm transaction").
Let's refactor the i2c c50 driver to use this same approach, and change
eve and reef boards to make use of DRIVER_TPM_TIS_ACPI_INTERRUPT for
specifying the TPM flow control interrupt.
This essentially reverts these two commits:
48f708d199 drivers/i2c/tpm/cr50: Initialize IRQ status handler before probe
94cc485338 drivers/i2c/tpm/cr50: Support interrupts for status
And ports this commit to i2c/tpm/cr50:
19e3d335bd drivers/spi/tpm: using tpm irq to sync tpm transaction
As a side effect the tpm_vendor_specific IRQ field goes back to its
original usage as the "TPM 1.2 command complete" interrupt, instead of
being repurposed to hold the flow control IRQ.

On Intel platforms utilizing the CR50 TPM the interrupts are routed
to GPIOs connected to the GPE blocks. Therefore, provide a common
implementation for tis_plat_irq_status() to reduce code duplication.
This code could be further extended to not be added based on
MAINBOARD_HAS_TPM_CR50, but that's all that's using it for now.

The CR50 TPM can do both SPI and I2C communication. However,
there's situations where policy needs to be applied for CR50
generically regardless of the I/O transport. Therefore add
MAINBOARD_HAS_TPM_CR50 to encompass that. Additionally,
once the mainboard has selected CR50 TPM automatically select
MAINBOARD_HAS_TPM2 since CR50 TPM is TPM 2.0.

MAINBOARD_HAS_SPI_TPM_CR50 describes a capability of the board and SPI_TPM
is only on if we actually want to compile in the TPM code. For example,
in src/drivers/i2c/tpm/Kconfig MAINBOARD_HAS_I2C_TPM_CR50 also doesn't
depend on SPI_TPM.
This problem manifests itself as the following build issue when building
with MAINBOARD_HAS_I2C_TPM_CR50 but without an explict "select TPM2":
src/Kconfig:296:error: recursive dependency detected!
src/Kconfig:296: symbol MAINBOARD_HAS_TPM2 is selected by MAINBOARD_HAS_TPM_CR50
src/Kconfig:408: symbol MAINBOARD_HAS_TPM_CR50 depends on MAINBOARD_HAS_SPI_TPM_CR50
src/drivers/spi/tpm/Kconfig:15: symbol MAINBOARD_HAS_SPI_TPM_CR50 depends on SPI_TPM
src/drivers/spi/tpm/Kconfig:1: symbol SPI_TPM depends on TPM2
src/Kconfig:396: symbol TPM2 is selected by MAINBOARD_HAS_TPM2
MAINBOARD_HAS_SPI_TPM_CR50 shouldn't depend on SPI_TPM.
