haswell/gma.c
The code to set the graphics translation table has been in the
mainboards, but should be in the northbridge support code.
Move the function, give it a better name, and enable support for > 4
GiB while we're at it, in the remote possibility that we get some 8
GiB haswell boards.

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.

The register indexes and bitfield masks were guarded by the UART8250 config
options, but it might be (is) necessary to use them in a driver that is
UART8250 like without actually using the 8250 driver itself. To avoid any name
collision with other drivers, also change the constant prefix from UART_ to
UART8250_.

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.

The pins on tegra are controlled by three different units, the pinmux, the
pin group controls, and the GPIO banks. Each of these units controls some
aspect of the pins, and they layer together and interact in interesting ways.
By default, the GPIOs are configured to pass through the special purpose IO
that the pinmux is configured to and so can be ignored unless a GPIO is needed.
The pinmux controls which special purpose signal passes through, along with
pull ups, downs, and whether the output is tristated. The pingroup controls
change the parameters of a group of pins which all have to do with a related
function unit.
The enum which holds constants related to the pinmux is relatively involved
and may not be entirely complete or correct due to slightly inconsistent,
incomplete, or missing documentation related to the pinmux. Considerable
effort has been made to make it as accurate as possible. It includes a
constant which is the index into the pinmux control registers for that pin,
what each of the functions supported by that pin are, and which GPIO it
corresponds to. The GPIO constant is named after the GPIO and is the pinmux
register index for the pin for that GPIO. That way, when you need to turn on
a GPIO, you can use that constant along with the pinmux manipulating functions
to enable its tristate and pull up/down mode in addition to setting up the
GPIO controls.
Also, while in general I prefer not to use macros or the preprocessor when
writing C code, in this case the set of constants in the enums was too large
and cumbersome to manage without them. Since they're being used to construct
a table in a straightforward way, hopefully their negative aspects will be
minimized.
In addition to the low level functions in each driver, the GPIO code also
includes some high level functions to set up input or output GPIOs since that
will probably be a very common thing to want to do.

A problem with including the tegra124 directory directly in the include path
is that it makes all headers in that directory first level headers available
everywhere including places that have nothing to do with the SOC, even headers
which were only intended for local use by tegra124 code. This change modifies
things a bit to be more like the way the arch headers are chosen. In the
tegra124 directory, there's an include directory which has an soc subdirectory
in it. That include directory is added to the include path, making it possible
to have headers private to the tegra124. When files specific to whatever tegra
is being built for are needed, you can include <soc/foo.h> and get the version
specific to that particular soc.
Also, the soc.h header file was overhauled to use enums instead of defines, to
consistently name things as far as their prefix (the less cryptic TEGRA instead
of NV_PA) and suffixes like "BASE", and to get rid of values which were
specific to U-Boot which we don't need. Since the only thing in the file were
address constants, I also renamed the file addressmap.h. It would be included
as:
<soc/addressmap.h>
which I think is easy to remember, does what you'd think it does from the
name, and won't conflict with other header files just minding their own
business in some other directory.

The UART / serial console is put in retention state by kernel during suspend /
resume path, which caused Coreboot not able to print any messages during resume.
Sending values to the padret_uart_opt inside PMU may release UART, but that may
also cause unexpected output when kernel is back. However, it's still very
helpful when we are debugging suspend/resume inside Coreboot.
To get UART message on resume, call wakeup_enable_uart() in boot block or
romstage (before console_init).

These symbols are not used anywhere in our C code, so
when using GCC's link time optimization feature they
will be dropped even though they're needed by libgcc.
Hence we need to mark them as used so GCC does not stumble
and fall over its own guts.

When passing '-ffreestanding' the 'main' romstage.c may no longer
necessarily be considered the entry point.
From the C specification in 5.1.2.1 Freestanding environment;
"In a freestanding environment (in which C program execution may take
place without any benefit of an operating system), the name and type of
the function called at program startup are implementation-defined."
Clang complains about these being missing as Clang is somewhat more
strict about the spec than GNU/GCC is. An advantage here is that a
different entry-point type-signature shall now be warned about at
compile time.

This patch cleans out a lot of unused variables in the
ARM Kconfig files and introduces CONFIG_RAMSTAGE_BASE
which is similar to CONFIG_RAMBASE on x86.
This gets rid of the hard coded assumption that on ARM
coreboot is always executed at the lowest DRAM address.
But in fact, this might not be true because we might want
coreboot to live at the end of RAM, or in SRAM

All this samsung_get_base_address_of_device_with_a_really_long_name()
boilerplate makes my eyes bleed... I think there are so much cleaner
ways to do this. Unfortunately changing this ends up touching nearly
every Exynos5 file, but I hope you agree that it's worth it (and the
sooner we get it over with, the better... I can't bring myself to make
another device fit into that ugly scheme).
This also removes the redundant EXYNOS5 base address definitions from
the 5420 directory when there are EXYNOS5420 ones, to avoid complete
confusion. The new scheme tries to use EXYNOS5 for base addresses and
exynos5 for types that are common between the two processors, and
EXYNOS5420/exynos5420 for things that have changes (although I probably
didn't catch all differences).

This change shows the source structure for nvidia Tegra and Tegra124
SOC. The problem we are trying to solve is that there is a large
amount of common code in the form of .c and .h files across many
different Tegra SOCs. The solution is to provide common code in a
single directory, but not to compile in the common code directory;
rather, we compile in a directory for a given SOC. Different SOCs
will sometimes need different bits of code from the common directory.
Tegra common code lives in tegra/, but there is no makefile there: if
a Tegra common file is needed in a SOC, it is referenced via a
Makefile in a specific Tegra SOC.
Another issue is includes. Include files in the common directory might be
accessed by a piece of code in an SOC directory. More problematically,
code in the common directory might require a file in an SOC directory.
We don't want to put the SOC name in an #include path, e.g.
in a C file in tegra/ is very undesirable, since we might be compiling
for a tegra114.
On some systems this is solved by a pre-pass which creates a set of
symbolic links; on others with nested #ifdef in the common code
which include different .h files depending on CPP variables.
In previous years, both LinuxBIOS and coreboot have tried these
solutions and found them inconvenient and error-prone.
We choose to solve it by requiring explicit naming of part of the path
of files that are in the common directory. This requirement, coupled
with two -I directives in the Makefile.inc, allows common and SOC
C code to incorporate both common and SOC .h files.
.c and .h files -- SOC or common -- name include
files in the common directory with the prefix tegra/, e.g.
SOC files will be included from the SOC directory if they have no prefix:
The full patch of clock.h will depend on what SOC is being compiled, which
is desirable.
In this way, a common file can pick up a specific SOC file without
creating symlinks or other such tricky magic.
We show this usage with one file, soc/nvidia/tega124/clock.c. This compiles.
The last question is where to put the prototype for the function
defined in this file -- soc.h?

This patch renames the x86 way of doing things to
explicitly mention CMOS (which is not available on
our ARM platforms) and adds an implementation to
get VBNV through the Chrome EC. We might want to
refine this further in the future to allow VBNV
in the EC even on x86 platforms. Will be fixed when
that appears. Also, not all ARM platforms running
ChromeOS might use the Google EC in the future, in
which case this code will need additional work.

This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.
This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow and Pit
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.
Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.
