On i945 the vram size is the default 8mb. It is also possible
to set it 1mb or 0mb hardcoding the GGC register in early_init.c
The intel documentation on i945, "Mobile Intel 945 Express Chipset
Family datasheet june 2008" only documents those three options.
They are set using 3 bits. The documententation also makes mention
of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it.
The other non documented (straight forward) bit combinations allow
to change the VRAM size to those other states.
What this patch does is:
- add those undocumented registers with their respective vram size to
the i945 NB code;
- make this a cmos option on targets that have this northbridge.
TEST: build, flash to target, set cmos as desired and boot linux.
On Debian it can be found using "dmesg | grep stolen".
NOTE: dmesg message about reserved vram are quite different depending
on linux version

Currently boards based on fsp_broadwell_de fail to compile if the config
switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the
usage of const for the address pointer in the functions writeb_, writew_
and writel_. The reason why it stayed hidden for so long is the fact that
the switch is used with the preprocessor and nobody really selects it
until there is a bug one want to find in this area.
This patch fixes the parameter type definition which solves the error.
In addition the config switch is not used on preprocessor level anymore
but instead on compiler level. This ensures that at least the code
syntax is checked on build time even if the config option is not
selected. Also prefix the messages with "SPI:" to make them more
meaningful in a full log.

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

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.
