In the case there is no the circuit diagram for motherboard, the
PCH/SoC GPIOs config is based on information from the inteltool
dump. However, available macros from gpio_defs.h can't define the
pad configuration from this dump:
0x0440: 0x0000002084000500 GPP_A8 CLKRUN#
0x0448: 0x0000102184000600 GPP_A9 CLKOUT_LPC0
0x0450: 0x0000102284000600 GPP_A10 CLKOUT_LPC1
To convert these raw DW0/DW1 register values to macros, the following
parameters must be set:
func - pad function,
pull - termination,
rst - pad reset config,
trig - rx level/edge configuration,
bufdis - rx/tx (in/output) buffer disable.
The patch resolves the above problem by adding a new macro for the
native function configuration:
PAD_CFG_NF_BUF_TRIG(pad, pull, rst, func, bufdis, trig)
These changes were tested on Asrock H110M-DVS motherboard [2].
It also resolves the problem of automatically creating pads

run_rom->data is a uint16_t, so use the appropriate read function.

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.)

- 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.

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.
