Currently we put the VPR write code just right before the AVP is going
to freeze. We have no idea does the write operation successful or not
before halting the AVP. And the power_on_main_cpu should be the last step
of that. So we make a fix to change the order.

nyan: Fix the build for big and blaze.
The display code for the tegra124 was cleaned up recently, but only the nyan
device tree was updated to match the new code, not big's or blaze's. This
change copies nyan's device tree over to those other two boards which will get
them building again. The settings may not be correct, but they'll be no less
correct than they were before. I also updated the copyright date for nyan.

TEST=Built for nyan, nyan_big, nyan_blaze. Booted on nyan_big and verified the
panel wasn't damaged by the new display code or settings.

This patch changes the ENTRY() macro in asm.h to create a new section
for every assembler function, thus providing dcache_clean/invalidate_all
and friends with the same --gc-sections goodness that our C functions
have. This requires a few minor changes of moving around data (to make
sure it ends up in the right section) and changing some libgcc functions
(which apparently need to have two names?), but nothing serious.
(You may note that some of our assembly functions have data, sometimes
even writable, within the same .text section. This has been this way
before and I'm not looking to change it for now, although it's not
totally clean. Since we don't enforce read-only sections through paging,
it doesn't really hurt.)
BUG=None
TEST=Nyan and Snow still boot. Confirm dcache_invalidate_all is not
output into any binary anymore since no one actually uses it.

The divider for the I2C clocks works differently than for other IP blocks and
needs to be set up to reflect that. There's also a large internal divider which
means you have to do extra calculations to determine what the frequency of the
bus itself will be based on the I2C controller clock. The new macro takes the
desired frequency of the bus itself and figures everything else out.

This patch changes several cache-related pieces to be cleaner, faster or
more correct. The largest point is removing the old
arm_invalidate_caches() function and surrounding bootblock code to
initialize SCTLR and replace it with an all-assembly function that takes
care of cache and SCTLR initialization to bring the system to a known
state. It runs without stack and before coreboot makes any write
accesses to be as compatible as possible with whatever state the system
was left in by preceeding code. This also finally fixes the dreaded
icache bug that wasted hundreds of milliseconds during boot.

Ipq8064 SBLs initialize the hardware to prepare it to run an arbitrary
user provided bootloader. The only bootloader requirements imposed by
the SBLs are that it is concatenated with the SBL chunks in the

load address).
This patch adds configuration options to specify the location of the
SBL blobs and to require MBN encapsulation of the bootblock.

This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).
BUG=None

Most of the code related to the mc146818 is not related to the RTC and is
really for managing the CMOS storage. Since we intend to add a generic API
for RTC drivers it's inconvenient for those functions to have an rtc_ prefix.
This CL renames those functions so they start with cmos_ instead. There are
some places where rtc_init was called with a comment that says something about
starting the RTC. That wasn't correct before (the RTC is always running), but
it looks a little odd now that the function is called cmos_init.
This CL also opportunistically cleans up some style problems in this file.

The offset of the device_nvs in the gnvs struct is expected to be
0x1000. It is actually 0x100 so padding is needed to move device_nvs
to the expected location. ACPI references to device_nvs objects will
be correct with the padding.
This was tested using a Micro Industries customized Baytrail-I board
based on the Intel Bayley Bay CRB. In intel/baytrail/nvs.h, there's
a Google customized structure located at 0x0100-0x0FFF that is
removed from the fsp_baytrail/nvs.h which explains the mismatch here.

ACPI globalnvs.asl expects the gnvs memory area size to be 0x2000.
Padding has been added to device_nvs struct to reserve the full
0x2000 bytes for gnvs usage.
No known issues are caused by having the GNVS area shorter than
what ACPI thinks. Since there's nothing defined in this area,
O/S shouldn't try to access it. Only problem might be if O/S
notices the SSDT is located within the GNVS defined area.
I verified that the next table written to memory (SSDT) is 0x2000
past GNVS start using a custom-designed Baytrail-I motherboard
based on the Intel Bayley Bay CRB.

Zero out the GNVS area so that uninitialized portions are defined.
Tests using Microsoft Windows (XP/7/8) gave a bluescreen bugcheck: A5
(ACPI_BIOS_ERROR) with the first parameter (0x00001000)
(ACPI_BIOS_USING_OS_MEMORY). Some ACPI enumerated devices use the
GNVS area to define whether they're enabled and their MMIO regions.
On my custom baytrail-based board and build, these devices were
disabled but GNVS had uninitialized data indicating the devices
were enabled with improper MMIO regions.
Should investigate further to see where the GNVS device values are
set if enabled and make sure they're set to valid values even when
the devices are disabled via the mainboard/devicetree.cb.

With SMM enabled the boot stopped while patching up global NVS in DSDT.
The cause is that both CPUs are assigned the same SMBASE address.
So update the "cpu_smm_do_relocation()" function so that each
CPU gets a different SMBASE address

This patch adds a new static assertion macro that can be used to check
the offsets in structures that overlay register sets at compile time. It
uses the _Static_assert() declaration from the new ISO C11 standard,
which is supported (even without -std=c11) by GCC after version 4.6.
(There is supposedly also support in clang, although I haven't tried
it... let's deal with compiler issues when/if they turn up.)
I've added it to all structures for our current ARM SoCs for now, and I
think every new register overlay we add going forward should use them
(at least for the last member, but feel free to add more if you think
it's useful).

tegra124: implement x2 mode for SPI transfers on CBFS media
This implements x2 mode when reading CBFS media over SPI.
In theory this effectively doubles our throughput, though the initial
results were almost negligibly better. Using a logic analyzer we see
a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we
want to see further gains here then we'll probably need to tune AHB
arbitration and utilization to eliminate bubbles/stalls when copying
from APB DMA.

This patch adds stub implementations of exception_init() to all archs
so that it can be called from src/lib/hardwaremain.c. It also moves/adds
all other invocations of exception_init() (which needs to be rerun in
every stage) close to console_init(), in the hopes that it will be less
likely overlooked when creating future boards. Also added (an
ineffective) one to the armv4 bootblock implementations for consistency
and in case we want to implement it later.

The pins for the UART had been configured manually using hardcoded offsets and
values. Now that we have pinmux functions for that sort of thing, we should
use that instead. This also provides a very simple test for the pinmux code.
Ultimately this code should be wrapped in a function which handles setting up
any of the UARTs which is appropriately parameterized and which would be
called from the bootblock main instead of being in it, but for now this is
sufficient.

We had a hardcoded version of the set_avp_clock_to_clkm function in the

The TPM driver expects to call i2c_read with zero address length. The i2c
driver wasn't prepared to handle that particularly in the case of reads
because it expected to send an address before switching over to read mode for
the data. This change also fixes up the read and write calls to consistently
be read32 and write32 instead of readl and writel.

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

tegra124: Add a test function which spams exclamation points on the UART.
This function spews characters on the console and, until we have a working
console, is an easy way to see whether the system boots to a particular point.
For some reason waiting for transmitter to be empty hangs, but transmitting
characters still works.

tegra124: Re-enable waiting for the transmitter to empty in the test function.
The compiler was emitting code compatible with armv7-a, but the bootblock was
running on a core which uses armv4t. By coincidence, it was emitting an
instruction which is unavailable on armv4t when checking the value of the
UART's LSR register. Now that the bootblock is compiled with more appropriate
flags, this code can be re-introduced.

tegra124: Seperate out the non-UART specific hardcoded init in the bootblock.
The hardcoded init in the test function in the bootblock is actually useful
generally because it doesn't belong in the UART driver itself but is necessary
for the UART to work. Until we have real implementations for the pinmux, etc.,
we can use that code to get the UART and console going.

tegra124: Implement and enable serial console support for tegra124.
The driver is very similar to the 8250 driver, except it isn't in two parts,
and it also spaces its registers 4 bytes apart instead of having them directly
adjacent to each other.
Also, eliminate the UART test function in the bootblock. It's no longer needed
since the actual console output serves the same purpose.
Right now the clock divisor is fixed for now, and we'll want to actually
figure out what value to use at some point.

The exynos directories had been moved from src/cpu to src/soc, but the name
of the chip_operations structure wasn't updated properly. That meant that the
SOCs never installed their memory resources and the ram stage would fail to

This minor refactoring patch changes the signature of all limited cache
invalidation functions in coreboot and libpayload from unsigned long to
void * for the address argument, since that's really what you have in
95% of the cases and I think it's ugly to have casting boilerplate all

The Exynos family and most ARM products are SoC, not just CPU.
We used to put ARM code in src/cpu to avoid polluting the code base for what was
essentially an experiment at the time. Now that it's past the experimental phase
and we're going to see more SoCs (including intel/baytrail) in coreboot.

The ARM Makefile was copied from x86 and then modified, and as a result it
was carrying a lot of baggage. On top of that, the extra complication made it
inflexible, and we need a lot of flexiblity in order to support the fact that
the Tegra124 starts on an ARMv4 coprocessor instead of one of the ARMv7 main
CPUs.

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.

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?
