Simon Glass 03cd118025 rockchip: spi: Improve SPI read efficiency
The SPI driver is quite slow at reading data. For example, with a 24MHz
clock on gru it achieves a read speed of only 13.9Mbps.

We can correct this by reading the status registers once, then reading as
many bytes as are available before checking the status registers again. It
seems likely that a status register read requires synchronizing with the
SPI FIFO clock domain, which takes a while.

TEST=run on gru and see the speed increase from 13.920 Mbps to 24.712 Mbps

We did yet another small adjustment to the PWM regulator ranges for
Kevin rev6... this patch reflects that in code. Also rewrite code and
descriptions to indicate that these new ranges are not just for Kevin,
but also planned to be used on Gru rev2 and any future Gru derivatives
(which as I understand it is the plan, right?).

Julius Werner b6bf1ddb91 gru: Add watchdog reset support
This patch adds support to reboot the whole board after a hardware
watchdog reset, to avoid the usual TPM issues. Work 100% equivalent to
Veyron.

From my tests it looks like both SRAM and PMUSRAM get preserved across
warm reboots. I'm putting the WATCHDOG_TOMBSTONE into PMUSRAM since that
makes it easier to deal with in coreboot (PMUSRAM is currently not
mapped as cached, so we don't need to worry about flushing the results
back before reboot).

BRANCH=None
BUG=chrome-os-partner:56600
TEST='stop daisydog; cat > /dev/watchdog', press CTRL+D, wait 30
seconds. Confirm that system reboots correctly without entering recovery
and we get a HW watchdog event in the eventlog.

Duncan Laurie 24de342438 mainboard/google/reef: Enable cr50 TPM interrupt
Enable the cr50 TPM and interrupt as GPE0_DW1_28 for use during
verstage.  The interrupt is left in APIC mode as the GPE is
still latched when the GPIO is pulled low.

Duncan Laurie a5e419c511 drivers/i2c/tpm/cr50: Support interrupts for status
Support reading the ACPI GPE status (on x86) to determine when
the cr50 is ready to return response data or is done processing
written data.  If the interrupt is not defined by Kconfig then
it will continue to use the safe delay.

This was tested with reef hardware and a modified cr50 image
that generates interrupts at the intended points.

Duncan Laurie 3d43a7c111 soc/intel/apollolake: Add function to read and clear GPE status
Implement the generic acpi_get_gpe() function to read and clear
the GPE status for a specific GPE.

Tested by watching GPE status in a loop while generating interrupts
manually from the EC console.

Duncan Laurie 5e3dad6622 soc/intel/apollolake: Initialize GPEs in bootblock
Initialize the GPEs from mainboard config in bootblock, so they
can be used in verstage to query latched interrupt status.

I still left it called in ramstage just to be sure that the
configuration was not overwritten in FSP stages.

Tested by reading and reporting GPE status in a loop in verstage
and manually triggering an interrupt on EC console.

Duncan Laurie 884dfe6329 x86: acpi: Add function for querying GPE status
Add a function that can be implemented by the SOC to read
and clear the status of a single GPE.  This can be used
during firmware to poll for interrupt status.

Rename the low-level functions from iic_tpm_read/write to
cr50_i2c_read/write to better match the driver name, and pass in the
tpm_chip structure to the low-level read/write functions as it will
be needed in future changes.
