Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

spd.bin can reside anywhere in CBFS, and we only use CBFS APIs to
access and read it. As such, there is no need to hardcode it, and it
can collide with mrc.bin or mrc.cache on some boards. Do not use a
specific position for spd.bin, but instead let cbfstool find the
optimal placement.

Peppy SPD table has 4GB configurations followed by 2GB configurations.
Current implementation does remapping to point 2GB configuration to the
same SPD index as the 4GB. This is different than Falco, which simply
duplicates the SPD data for all configurations. To simplify probing in
mosys, copy the Falco implementation of duplicating SPD data.

On some systems there may be 2GB SKU that is the same as the
4GB SKU but just one channel of memory. In that case we need
to ensure that both copies of the same SPD source end up
populated by ensuring that repeated entries are included by
using $+ instead of $^.
Alternatively we could do the check inside romstage, but it
is already set to behave this way if the SPD gets populated
correctly.
I changed spd_index to 3 in falco romstage to force it to
pretend it was a 2GB config of the same memory, then booted
to ensure it was indeed limited to 2GB.
