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.

Since commit 17fec8a0 [1]
drm/i915: Use Graphics Base of Stolen Memory on all gen3+
present in the Linux kernel since version 3.12, 3D does not work
anymore [2].
Comparing the graphics registers, in this case that means output of
`intel_reg_dumper`, the vendor Video BIOS is setting the register
PGTBL_CTL/PGETBL_CTL, only documented in the i965 datasheet [3], to
`0x3ffc0001` on a system with 1 GB of RAM, while native graphics init
sets it to `0x3f800001`.
Currently native graphis init sets the GTT right above the base
address of stolen memory. The Video BIOS sets it below the top of
memory. The Linux Intel driver expects it to be below top of memory, so
do it this way, by setting the address to TOM minus the size of the GTT,
which is hardcoded to 256 KiB.
As `PGETBL_CTL` is zero by default, reading its value in the beginning
is not necessary and is only confusing. Make it clear that the code
calculates the value.
There is still a PTE error reported during boot, but 3D works
with Linux 3.12+ and no user visible problems are shown.

AMD/CIMx: Add functions for AMD PCI IRQ routing
This change also moves the PCI INT functions to
southbridge/amd so that they can be used by CIMX and
AGESA. The amd/persimmon board is updated for this
change.

First of many to remove guarding the inclusion of headers based on
CONFIG_ options. This *potentially* could hide issues such as functions
being swapped from under our feet, since different runtime behaviour
could be declared with the function same name and type-signature. Hence,
depending on the header we happen to get may change runtime behaviour.

The PCI_INTR table is an Index/Data pair of I/O ports
0xC00 and 0xC01. This table is responsible for physically
routing IRQs to the PIC and IOAPIC. The settings given
in this table are chipset and mainboard dependent, so the
table values will reside in the mainboard.c file. This
allows for a system to uniquely set its IRQ routing.
The function to write the PCI_INTR table resides in
cimx_util.c because the indices into the table have
the same definitions for all SBx00 FCH chipsets.
The next piece is a function that will read the PCI_INTR
table and program the INT_LINE and INT_PIN registers in
PCI config space appropriately. This function will read
a devices' INT_PIN register, which is always hardcoded to
a value if it uses hardware interrupts. It then uses this
value, along with the device and function numbers to
determine an index into the PCI_INTR table. It will read
the table and program the corresponding value into the PCI
config space register 0x3C, INT_LINE. Finally, it will set
this IRQ number to LEVEL_TRIGGERED on the PIC because it is
a PCI device interrupt and the must be level triggered.
For example, the SB800 USB EHCI device 0:18.2 has an INT_PIN
value hardcoded to 2. This corresponds to PIN B. On the
Persimmon mainboard, I want the USB device to use IRQ 11. I
will program the PCI_INTR table at index 0x31 (this USB device
index) to 11. This function will then read the INT_PIN register,
read the PCI_INTR table, and then program the INT_LINE register
with the value it read. It will then set the IRQ on the PIC to
LEVEL_TRIGGERED by writing a 1 to I/O port 0x4D1 at bit position 4.
Also, the SB700 has slightly different register definitions than
the newer SB800 and SB900 so it needs its own set of #defines for
the pci_intr registers.
Only the Persimmon mainboard is adapted to this change as an
example for other mainboards.
