This patch runs basic NAND initialization code on Proto 0.2 boards which
have been reworked for NAND. It makes sense to do this in coreboot for
two reasons:
- In general, it is reasonable for coreboot to initialize clocks and such
in preparation for depthcharge's use. Waiting times can be pooled, and
the initialization itself here is very fast.
- There is a kernel bug which requires that the clock is already initialized
before the kernel loads NAND support. coreboot is a more sensible place
to put a workaround than depthcharge because depthcharge initializes
things lazily, but when booting from USB, depthcharge won't need to look
at NAND.
This change involves bringing in an additional header file, ebi2.h, from U-Boot.
TEST=Booted a kernel from USB and verified that NAND came up without any
depthcharge hacks, whereas previously a USB-booted kernel would be unable
to access NAND even with the same drivers compiled in due to an initialization
failure.

The function to read board IDs from tristate GPIOs currently supports
two output modes: a normal base-3 integer, or a custom format where
every two bits represent one tristate pin. Each board decides which
representation to use on its own, which is inconsistent and provides
another possible gotcha to trip over when reading unfamiliar code.
The two-bits-per-pin format creates the additional problem that a
complete list of IDs (such as some boards use to build board-ID tables)
necessarily has "holes" in them (since 0b11 does not correspond to a
possible pin state), which makes them extremely tricky to write, read
and expand. It's also very unintuitive in my opinion, although it was
intended to make it easier to read individual pin states from a hex
representation.
This patch switches all boards over to base-3 and removes the other
format to improve consistency. The tristate reading function will just
print the pin states as they are read to make it easier to debug them,
and we add a new BASE3() macro that can generate ternary numbers from
pin states. Also change the order of all static initializers of board ID
pin lists to write the most significant bit first, hoping that this can
help clear up confusion about the endianness of the pins.

We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

We have two drivers for a 100%-identical peripheral right now, mostly
because we couldn't come up with a good common name for it back when we
checked it in. That seems like a pretty silly reason in the long run.
Both Tegra and Rockchip SoCs contain UARTs that use the common 8250
register interface (at least for the very basic byte-per-byte transmit
and receive parts we care about), memory-mapped with a 32-bit register
stride. This patch combines them to a single 8250_mmio32 driver (which
also fixes a problem when booting Rockchip without serial enabled, since
that driver forgot to check for serial initialization when registering
its console drivers). The register accesses are done using readl/writel
(as Rockchip did before), since the registers are documented as 32-bit
length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce
APB accesses to have the full word length. Also fixed checkpatch stuff.
A day may come when we can also merge this driver into the (completely
different, with more complicated features and #ifdefs) 8250 driver for
x86 (which has MMIO support for 8-bit register stride only), both here
and in coreboot. But it is not this day. This day I just want to get rid
of a 99% identical file without expending too much effort.

Don't attempt to scan the PCI bus if the bridge is disabled. When
the PCI bridge is not setup and enabled, it is possible for the
secondary bus register to contain the value zero (0). In this case
the usb_scan_pci_bus routine gets into an infinite recursive loop
which ends only when the heap or stack is exhausted. This patch
verifies that the PCI bridge is enabled by verifying that it is
enabled for either memory or I/O operations. When enabled, the
secondary bus is scanned.

In order to properly support more arm64 SoCs PSCI needs
to handle the hierarchy of cpus/clusters within the SoC.
The nodes within PSCI are kept in a tree as well as
a depth-first ordered array of same tree. Additionally,
the PSCI states are now maintained in a hierachal manner.
OFF propogates up the tree as long as all siblings are
set to OFF. ON propogates up the tree until a node is
not already set to OFF.
The SoC provides the operations for determining how many
children are at a given affinity level. Lastly, the
secmon startup has been reworked in that all non-BSP CPUs
wait for instructions from the BSP.

C0_COUNT register is a free running counter clocked by the CPU
frequency divided by two. On the FPGA board it results in 25 MHz, on
real SOCs it will have to be figured out later.
Some magic addresses and numbers are used to find out if the code is

timestamp_get() and timer_monotonic_get() are kept in the same file.
The CPU initialization makes sure that CO COUNT is in fact enabled and

This patch is the start of a series to change all non-x86 SoC-specific
headers to be included as <soc/header.h> instead of the old
<soc/vendor/chip/header.h> or "header.h". It will add an include/soc/
directory under every src/soc/vendor/chip/ and append the .../include/
part of that to the global include path.
This matches the usage of <arch/header.h> for architecture-specific
headers and had already been done for some headers on Tegra. It has the
advantage that a source file which does not know the specific SoC used
(e.g. Tegra files common for multiple chips, or a global include file)
can still include SoC-specific headers and access macros/types defined
there. It also makes the includes for mainboard files more readable, and
reduces the chance to pull in a wrong header when copying mainboard
sources to use a different-related SoC (e.g. using a Tegra124 mainboard
as template for a Tegra132 one).
For easier maintainability, every SoC family is modified individually.
This patch starts out by changing Rk3288. Also alphabetized headers in
affected files since we touch them anyway.
BUG=None
TEST=Whole series: compared binary images for Daisy, Nyan_Blaze,

Paging code is tricky and figuring out what is wrong with it can be a
pain. This patch tries to ease the burden by giving a little more
information for prefetch and data aborts, dumping the Instruction Fault
Address Register (IFAR), Instruction Fault Status Register (IFSR) and
Auxiliary Instruction Fault Status Register (AIFSR) or the respective
Data registers. These contain additional information about the cause of
the abort (internal/external, write or read, fault subtype, etc.) and
the faulting address.
BUG=None
TEST=I have read through enough imprecise asynchronous external abort
reports with this patch that I learned the bit pattern by heart.

Remember the XN bit? The one we had so much fun with on Nyan (LPAE)
because not setting it allows random instruction prefetches to device
memory that hang the system every few thousand boots? Thankfully, we had
always been setting it in the non-LPAE MMU code already...
"When the XN bit is 1, a Permission fault is generated if the processor
attempts to execute an instruction fetched from the corresponding memory
region. However, when using the Short-descriptor translation table
format, the fault is generated only if the access is to memory in the
Client domain, see Domains[...]" - ARM A.R.M. section B3.7.2
Oops. This patch changes our Domain Access Control Register (DACR) to
set domain 0 (the only one we are using) to Client. This means that
access permissions (AP[2:0] bits) become enforced, but they are already
set to full access (0b011). It also means that non-LPAE systems will not
be allowed to execute from DCACHE_OFF memory with enabled MMU anymore.
As far as I can see, Veyron_Pinky has been the only board that does
that.
BUG=chrome-os-partner:32118
TEST=Booted Veyron_Pinky with MMU in the bootblock, saw hangs that look
like spurious prefetches and confirmed that this patch fixes them.

Solving the DACR bug will mean that XN bits suddenly become enforced on
non-LPAE systems, and we will no longer be able to execute out of a
region mapped DCACHE_OFF. When we enable the MMU in romstage we are
still executing out of SRAM, so we would instantly kill ourselves.
Solve this issue by enabling the MMU earlier (in the bootblock) and
mapping the SRAM regions as DCACHE_WRITETHROUGH. They should really be
DCACHE_WRITEBACK, but it looks like there might be hardware limitations
in the Cortex-A12 cache architecture that prevent us from doing so.
Write-through mappings are equivalent to normal non-cacheable on the A12
anyway, and by using this attribute we don't need to introduce a new
DCACHE_OFF_BUT_WITHOUT_XN_BIT type in our API. (Also, using normal
non-cacheable might still have a slight speed advantage over strongly
ordered since it should fetch whole cache lines at once if the processor
finds enough accesses it can combine.)

This patch adds an mmu_config_range_kb() function, which can set memory
types at the 4KB level by chaining a fine-grained page table to an
existing superpage entry. It is only intended for special cases where
this level of precision is really necessary and therefore comes with a
few practical limitations (the area for each invocation must be confined
within a single superpage, and you are not allowed to remap the same
region with mmu_config_range() again later). Since the fine-grained page
tables need some space, boards intending to use this feature must define
a TTB_SUBTABLES() region in their memlayout.ld.
BUG=chrome-os-partner:32848
TEST=Booted both Veyron_Pinky (normal) and Nyan_Blaze (LPAE), ensured
that they still work. Checksummed the page tables with and without this
patch, confirmed that they end up equal. Hacked in some subtable test
entries, hexdumped all tables and manually confirmed that they look as
expected.

This patch does some general cleanup in the Rockchip clock code, and
adds some more assertions regarding the PLL VCO and output frequency
ranges. It changes all PLL divisors to use the lowest values that can
still hit the target frequency, since higher NR values lead to higher
jitter and higher NO values increase power draw.
Also change DDR3 frequency code to hardcode the optimal divisors for
certail frequencies. As a little hack we will interpret 666000000 to
actually mean 666666666.6P (and analogous for 533MHz), since that's what
you usually want for memory.

This change re-writes the spi_xfer() function to support full-duplex
transfers.
Even though the code looks much different, the same basic algorithm
for setting up the transfer is used. The main difference is that
reads from rxdr and writes to txdr occur simultaneously and accounting
is more complicated, so I separated the higher-level accounting
portion from the low-level FIFO handling portion to simplify things.

Over the course of time there have been some implicit assumptions
about cbmem being available for find() or add() operations. However,
the cbmem area was never fully recovered until entering the state
machine: BS_ON_ENTRY into BS_PRE_DEVICE. Correct this assumption
by explicitly calling cbmem_initialize() in the EARLY_CBMEM_INIT
case.
This, however, doesn't fix timestamp_init() showing an error about
not being able to allocate the timestamp table.

If you try to boot a VBOOT2_VERIFY_FIRMWARE with less than 4K CBFS cache
right now, your system will try and fail to validate the FMAP signature
at (u8 *)0xFFFFFFFF and go into recovery mode. This patch avoids the
memcmp() to potentially invalid memory, and also adds an error message
to cbfs_simple_buffer_map() to make it explicit that we ran out of CBFS
cache space.
BUG=None

Although on some systems va_end is a no-op, it is good practice
to use va_end, especially since the manual states:
"Each invocation of va_start() must be matched by a corresponding
invocation of va_end() in the same function."

This makes "make menuconfig" also work on systems where ncurses is not
installed in a standard location (such as on NixOS).
This patch changes ccflags() so that it tries pkg-config first, and only
if pkg-config fails does it go back to the fallback/manual checks. This
is the same algorithm that ldflags() already uses.

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).
BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies
with ToT and looked for red flags.

This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.
This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)
It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.
BUG=None
TEST=None (tested together with dependent patch).
