A pad number is passed into gpi_status_get() to determine if its
associated bit is set from a generated event. However, the
implementation wasn't taking into account the gpi_status_offset
which dictates the starting offset for each community. Additionally,
the max_pads_per_group field is per community as well -- not global.
Fix the code to properly take into account the community's
gpi_status_offset as well as the max_pads_per_group.

in mind. Controllers, channels and DIMMs are all presented in their phy-

Our structure packing for Rockchip's gpio_t was chosen arbitrarily. ARM
Trusted Firmware has since become a thing and chosen a slightly
different way to represent GPIOs in a 32-bit word. Let's align our
format to them so we don't need to remember to convert the values every
time we pass them through.

We've just decided to remove the only known use of the VBSD_SW_WP flag
in vboot (https://chromium-review.googlesource.com/c/575389), since it
was unused and never reliable on all platforms anyway. Therefore, we can
now also remove the coreboot infrastructure that supported it. It
doesn't really hurt anyone, but removing it saves a small bit of effort
for future platforms.

1. Explicitly add LOGICAL to the reset macro name to make it explicit
that the values are logical.
2. Reword some of the comments and combine them into single comment
instead of scattering the comments throughout.
3. Use c99 struct initializers for the reset mapping array.
4. For the chipset specific values use literals that match the hardware.
5. Use 'U' suffixes on the literals so we don't trip up compiler being
over zealous on undefined behavior.
6. Use unsigned and fixed-width types for the reset mapping structure
since the code is reliant on matching up with a register definition.
7. Fix formatting that can fit < 80 cols.

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.

Don't need this additional 2ms delay as PCR read after sideband write
help to fix original hard hang issue.
