cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

2f389f151a arch/arm: Pass cbmem_top to ramstage via calling argument
This solution is very generic and can in principle be implemented on
all arch/soc.

Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

Mechanisms set in place to pass on information from rom- to ram-stage
will be placed in a followup commit.

340e4b8090 lib/cbmem_top: Add a common cbmem_top implementation
This adds a common cbmem_top implementation to all coreboot target.

In romstage a static variable will be used to cache the result of
cbmem_top_romstage.

In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable
needs to be populated by the stage entry with the value passed via the
calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the
same implementation as will be used as in romstage.

783982751d cpu,mb,soc: Init missing lb_serial struct fields
Initialize the input_hertz and uart_pci_addr fields of the lb_serial
struct to prevent later undefined reads in lb_add_serial(). This was
done for exynos5420 in commit ff94e00362 (soc/samsung/exynos5420/uart.c:
Init new serial struct variables), and this patch finishes the rest.
Note that not all of the drivers can have the UART PCI address
configured at build time, so a follow-up patch will be needed to correct
those ones.

0097f5589e vboot: standardize on working data size
Previously, the size of memory made for vboot_working_data
through the macro VBOOT2_WORK was always specified in each
individual memlayout file.  However, there is effectively no
reason to provide this customizability -- the workbuf size
required for verifying firmware has never been more than 12K.
(This could potentially increase in the future if key sizes
or algorithms are changed, but this could be applied globally
rather than for each individual platform.)

This CL binds the VBOOT2_WORK macro to directly use the
VB2_WORKBUF_RECOMMENDED_DATA_SIZE constant as defined by vboot
API.  Since the constant needs to be used in a linker script, we
may not include the full vboot API, and must instead directly
include the vb2_constants.h header.

7e0dea6317 symbols.h: Add macro to define memlayout region symbols
When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.

This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).

Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

755db95d1a (console,drivers/uart)/Kconfig: Fix dependencies
The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow
backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART,
because it's using its interface. The individual UART drivers
select DRIVERS_UART, because they implement the interface and
depend on the common UART code.

Some guards had to be fixed (using CONSOLE_SERIAL now instead of
DRIVERS_UART). Some other guards that were only about compilation
of units were removed. We want to build test as much as possible,
right?

029dfff30c i2c: Move to Linux like struct i2c_msg
Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.

Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.

The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.

Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.

Patched with Coccinelle using the clumsy spatch below and some manual
changes:

* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

01f9aa5e54 Consolidate reset API, add generic reset_prepare mechanism
There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.

This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).

Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

1210b41283 vboot: Select SoC-specific configuration for all Chrome OS boards
Some Chrome OS boards previously didn't have a hardcoded vboot
configuration (e.g. STARTS_IN_BOOTBLOCK/_ROMSTAGE, SEPARATE_VERSTAGE,
etc.) selected from their SoC and mainboard Kconfig files, and instead
relied on the Chrome OS build system to pass in those options
separately. Since there is usually only one "best" vboot configuration
for a certain board and there is often board or SoC code specifically
written with that configuration in mind (e.g. memlayout), these options
should not be adjustable in menuconfig and instead always get selected
by board and SoC Makefiles (as opposed to some external build system).

(Removing MAINBOARD_HAS_CHROMEOS from Urara because vboot support for
Pistachio/MIPS was never finished. Trying to enable even post-romstage
vboot leads to weird compiler errors that I don't want to track down
now. Let's stop pretending this board has working Chrome OS support
because it never did.)

d972f78e75 linking: link bootblock.elf with .data and .bss sections again
Currently coreboot expects the loader to clear the bss section
for all stages. i.e. stages don't clear their own bss. On ARM
SoCs the BootROM would be responsible for this. To do that
one needs to include the bss section data (all zeros) in the
bootblock.bin file. This was previously being attempted by
keeping the .bss info in the .data section because objcopy
happened zero out non-file allocated data section data.

Instead go back to linking bootblock with the bss section
but mark the bss section as loadable allocatable data. That
way it will be included in the binary properly when objcopy
-O binary is emplyed. Also do the same for the data section
in the case of no non-zero object values are in the data
section.

Without this change the trick of including .bss in .data
was not working when there wasn't a non-zero value object
in the data section.

BUG=None
BRANCH=None
TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains
     the cleared bss.

899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

c6588c5af9 coreboot: introduce boot_device
The boot_device is a region_device that represents the
device from which coreboot retrieves and boots its stages.
The existing cbfs implementations use the boot_device as
the intermediary for accessing the CBFS region. Also,
there's currently only support for a read-only view of
the boot_device. i.e. one cannot write to the boot_device
using this view. However, a writable boot_device could
be added in the future.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.
