The memcpy(), memmove() and memcmp() functions use word by word
operations regardless of the pointer alignment. Depending on the
platform, this could lead to a crash.
This patch makes the memcpy(), memmove() or memcmp() operate byte per
byte if they are supplied with unaligned pointers.

The FSP 2.0 path uses postcar to decompress ramstage. Since postcar
is entirely RAM based there's no need to have an excessively large
stack for the lzma decompression buffer. Therefore, reduce the stack
required to 1 KiB like apollolake.

At process _start, the stack is expected to be aligned to a
16-byte boundary. Upon entry to any function the stack frame
must have the end of any arguments also aligned. In other words
the value of %esp+4 or %rsp+8 is always a multiple of 16 (1).
Align the stack down and change the method for executing
car_stage_entry from jmp to call which should preserve proper
alignment regardless of a 32- or 64-bit build.
Although 4-byte alignment is the minimum requirement for i386,
some AMD platforms use SSE instructions which expect 16-byte.

1. Due to reset signal, PMIC loses its internal register state. This
causes PMIC to be in improper state after sleep.
2. The intent of reset signal is to reset internal state of PMIC (which
happens once during power on), hence avoid asserting reset signal
when not needed.
3. As per PMIC (TPS68470) datasheet, device can be kept in SLEEP mode
when not in use to save max possible power.
To fix the same, do not reset PMIC while entering sleep.
By keeping PMIC in SLEEP mode, Power consumption is < 1uW (Typ) upto
3.63uW (Max). Refs: TPS68470 datasheet.
Measured value: 0.66uW
TEST= Build the firmware for Soraka & boot to OS. Do S3 resume & check
whether PMIC internal registers state are preserved.

This reverts commit 5535cead (intel/skylake: Disable SaGv in
recovery mode).
Commit 5535cead disables SaGv in recovery mode to save few seconds
booting time as we were doing memory training on every recovery flow.
Now we don't need to perform MRC training on every recovery boot
due to RECOVERY_MRC_CACHE implementation in place. Hence we don't
need to define different SaGv policy between Normal (developer) mode
and recovery mode to save few seconds.
Using different SaGv parameters between recovery and all other mode
has some significent drawbacks over warm reboot cycle. We are seeing
a MRC traning hang in eve/soraka/poppy devices with below use case.
Step 1: Boot system in developer mode (first time RW_MRC training)
Step 2: Set recovery_request=1 (using crossystem) and issue “reboot”
from OS
Step 3: System will perform recovery mode MRC training and boot to
OS (first time RECOVERY_MRC training)
Step 4: Issue “reboot” from OS console.
Step 5: System wil boot in developer mode (using RW_MRC cache)
Step 6: Set recovery_request=1 (using crossystem) and issue “reboot”
from OS
Step 7: System will pick RECOVERY_MRC_CACHE and will hang during
MRC training.
This patch fixes issue mentioned above and ensures system boot to
OS without any hang if we change mode (dev<->recovery) over warm
reset.
BUG=b:63515071
BRANCH=none
TEST=manual stress testing of dev<->recovery mode over warm boot.
No MRC hang with this fix on eve/soraka/poppy devices.

The macro FPGA_SET_PARAM was introduced to make the setting of different
FPGA registers with the appropriate values from hwinfo more
transparent. The hwilib takes care about the size of the provided buffer
where the requested value should be stored in. The fields in hwinfo have
not always the same size as the matching registers in the FPGA. So to
avoid errors resulting in a too small buffer when calling hwilib_get_field()
the buffer is now fixed to 32 bit and will be casted to the destination
type when the value is written into the FPGA register.
Changing the field size in hwilib would be the wrong way as the defined
lengths are specified this way to be expandable in the future.
In addition the number of maximum supported temperature sensors is
increased to 8 as the FPGA now supports more.
