Aseda Aboagye 19dca2b046 mb/google/eve: Enable wake from MKBP events in S3
We would like to wake eve up in suspend from an MKBP event.  This commit
simply enables MKBP events to wake the system in suspend using the
existing host event interface.  There is an accompanying series of
patches in the EC firmware for eve that will allow a MKBP wake mask to
be configured.

BUG=chromium:786721
BRANCH=firmware-eve-9584.B
TEST=Build and flash eve, generate MKBP events on the EC and verify
that the system wakes up in suspend.

The processor P_BLK doesn't support throttling. This behaviour could be
emulated with SMM, but instead just update the FADT to indicate no support
for legacy I/O based throttling using P_CNT.

We have _PTC defined in SSDT, which should be used in favour of P_CNT by
ACPI aware OS, so this change has no effect on modern OS.

Drop all occurences of p_cnt_throttling_supported and update autoport
to not generate it any more.

Jacob Garber 52f3bd158a sb/amd/sb800: Remove bit shift that does nothing
This bit shift attempts to set bits 8 and 9 of the byte variable (counting
from 0). However, as the name suggests, this variable is only 8 bits
wide, so the shift does nothing. Reading section 7.5 of the
AMD SB800-Series Southbridges Register Programming Requirements manual,
bits 8 and 9 are already set by default, so we can remove the bit shift.
(Alternatively, we could try setting the corresponding bits one byte
higher in 0xF1 if needed.)

Jacob Garber d92137adab nb/via/vx900: Ensure framebuffer size is within limits
- Use log2() when rounding down size_mb to the closest power of 2.
  Do a sanity check beforehand that size_mb is nonzero, else log2()
  will return -1 and there will be an undefined integer shift.
- The framebuffer size needs to be between 8 and 512 MiB, so check
  after all the calculations are done to make sure this is the case.

Jacob Garber 4c33a3aaa3 src: Make implicit fall throughs explicit
Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.

    switch (x) {
    case 1:
            y += 1;
	    /* fall through */
    case 2:
            y += 2;
	    /* fall through - but this time with an explanation */
    default:
            y += 3;
    }

This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

Jacob Garber 78107939de nb/intel/pineview: Remove dead code in switch
This switch was likely copy-pasted from the one right above it. However,
the MEM_CLOCK_800MHz case isn't needed, since that is explicitly checked
and avoided before the while loop. With that gone, only the
667MHz/default case is left, which we don't need to switch over anymore.

to be stored back in the battery object.  This value needs to be
passed as a reference to an object to prevent it from being evaluated

This was tested by instrumenting the _BST method in the primary
battery and ensuring the value can be updated by the BBST method.

Subrata Banik c76bfac088 device/oprom/realmode: Add vbe return status support as per VBE spec 3.0
Existing coreboot oprom implementation relies on user selected
vesa mode through CONFIG_FRAMEBUFFER_VESA_MODE Kconfig option
and expects that all oprom might support user selected vesa mode.

Take an example:
Enabling AMD external radeon PCIE graphics card on ICLRVP with
default vesa mode 0x118. Unable to get valid X and Y resolution
after executing vbe_get_mode_info() with 0x4118, return data
buffer shows 0x0 resolution. It causes further hang while trying
to draw bmpblk image at depthcharge.

This patch checks for output register AH in all vbe function
(0x3 and 0x4f00/1/2) and die() if returns error.
