In order to provide time for the S0 rails to discharge one needs
to be able to set the SLP_S3_L assertion width. The hardware default
is 60 microcseconds which is not slow enough on most boards. Therefore
provide a devicetree option for the mainboard to set accordingly
for its needs. An unset value in devicetree results in a conservative
2 second SLP_S3_L duration.

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.

This patch adds support to reboot the whole board after a hardware

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

min/max voltage may be different between revs.
With the pwm regulator, this patch changes the little cpu frequency from

This also means we decide to drop the ES1 because it may fail to

Other platforms may provide similar support, but they do that

is used to calculate the _car_region_end in car.ld. If the FSP CAR
requirement is greater than or even close to DCACHE_RAM_SIZE then,
the CAR region for FSP will be determined to be below the overall
CAR region boundary i.e, out of CAR memory range.
This is working with FSP 1.1 because we provide the FspCarSize
and FspCarBase explicitly in a UPD. Hence, FSP is still able to
use the upper region of CAR memory for its purpose.
However, it will be a problem in case of FSP2.0 where FSP usable CAR
is calculated using _car_region_end.
So, Remove the the use of DCACHE_RAM_SIZE_TOTAL and set

This patch sets some magic number in magic undocumented registers that
are rumored to make USB 2.0 signal integrity better on Kevin. I don't
see any difference (unfortunately it doesn't solve the problems with
long cables on my board), but I guess it doesn't hurt either way.

This patch enables serial debug functionality for ASL code based on
UART type(legacy/LPSS).
From Skylake onwards all Intel platform uses LPSS based UART for serial
console hence provide option to redirect ASL log over LPSS UART.
Example:

APRT (OBJ)
APRT ("CORE BOOT")
Output:
0x12
CORE BOOT

When booting Linux as a coreboot payload, serial access does not work
properly. This is because the setup code erroneously sets IRQ3 and
IRQ4 to level. The UART on Broadwell is 8250/16550 compatible, thus
ISA and edge-triggered.
This change is not necessary on the non-FSP version of Broadwell support.
The non-FSP version does not set these IRQ overrides.
Fix verified booting Linux 4.6.0-rc2 on Intel Camelback Mountain CRB,
using Intel FSP 1.0.
