Steven Sherk 1cbabb00d9 Add MMCONF resource to AMD fam15tn PCI_DOMAIN
In the process of verifying change it was discovered the MMCONF
default base address 0xA0000000 was set below mem_top 0xE0000000
and bus number 256 wasn't a relistic number. The Kconfig defaults were
changed to mirror fam15 defaults base address 0xF8000000 and bus
number 64. Verified changes with boot to OS.

This is a port of the following:
commit d5c998be99

	The coreboot resource allocator doesn't respect resources
	claimed in the APIC_CLUSTER. Move the MMCONF resource to the
	PCI_DOMAIN to prevent overlap with PCI devices.

David Hendricks 2354ef8869 exynos/snow: get rid of board-specific arbitration code
Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
EC can act as a master, so to avoid conflicts an arbitration
mechanism consisting of two GPIOs is used.

By default, the AP "owns" the bus unless it is off (in which case
the EC doesn't monitor the arbitration pins). This means the boot
firmware does not need to worry about these lines. The payload may
if it needs to communicate with the EC, though.

In any case, board-specific bus arbitration logic does not belong
in a low-level driver that is supposed to be generic for an entire
CPU family. If the payload needs to talk to the EC, we'll deal with
it there.

Hung-Te Lin fe18792a08 armv7: Add 'bootblock' build class.
For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".

Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.

For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

Ronald G. Minnich 79e36d9060 Improve how our printk calls do_div by using constants.
The do_div code has a nice optimization in it when it is called with
constants. The current highly generalized use of it defeats those
optimizations and causes trouble on ARM, resulting in a complex and
buggy code path.

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)

This fixes an ongoing problem with ARM, will not harm X86, and will
help PPC should we ever want to support it again.
Plus, I don't have to ever try to understand the div64 assembly and where
it's going wrong :-)

Ronald G. Minnich bc3abbbaf0 armv7: don't hang on divide by zero
People make mistakes. Hanging the box is not a good reason to kill the firmware,
esp. since this is probably happening in a printk.

The only issue with the recursive call to printk is that we may
deadlock if we have locked something. But we can at least try.
Hanging is certainly not what we want ...

Ronald G. Minnich b7e0535862 Exynos5250: Get DDR3 working by changing what is compiled and add a function
This is a minor set of changes to get DDR3 going.

Move compilation of DDR3 startup to the romstage. Fix a prototype that
was missing a void. Remove a function that is overly flexible, and
even though it is overly flexible only actually can handle one type of
RAM. Mainboards only support one type of DRAM, so create a function
to explicitly initialize the type of DDR we have -- DDR3.

With these changes, and the previous changes, google snow is ready to run
the ramstage.

Hung-Te Lin 6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.

Ronald G. Minnich 88e4691ed9 Exynos5250: add debug prints to DDR3 startup code.
It can be handy to have debug prints as DRAM is started up, so that
in the case of failure (does that ever happen?) you've got some
idea where it failed.

This patch adds some DEBUG_SPEW prints to the DDR3 code. I am doing this
as its own CL because we may find we want to revert it. That's unlikely
but it is not impossible if we skew the timing in some way.

This code works for some trivial DRAM tests.

Ronald G. Minnich 770996fd86 Exynos5250: make vendor enums in the timing array more debuggable.
The timing array is crucial to proper operation of DRAM.

Getting a valid pointer to it is hence very important. Unfortunately,
the constants chosen for the vendor were '1', and '2', (this in a
32-bit word) which in a debug print makes it almost impossible to tell
if you've got a misaligned pointer. Note: coreboot people did not
choose them :-)

So, give them values which are extremely unlikely to occur elsewhere
in the array (or in memory, for that matter).

Given the frequency with which this check occurs, i.e. once, I would
much prefer strings but I expect I'd get shouted down on that
one. Constants in this case are an almost useless optimization but
we'll go with them for now. Note no space is saved by not using
strings: there's an entire function somewhere devoted to mapping the
enum to a string!

Debug prints of pointers to structs in this array are now far more
useful than they were.

See snarky comment in the code (left there to make sure nobody gets
tempted to get fancy again). Comment now less snarky.

This is tested on google snow to the point that the DRAM works.
