Rename Kconfig options for secmon and spintable to be prefixed with
ARM64_ instead of ARCH_, which seems to be the standard throughout the
rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this
provides a clearer separation between generic options that are selected
by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to
some of the MAINBOARD_HAS_... we have) and options that only make sense
in the context of a single architecture.

Remove the secmon Kconfig guard from Makefiles that add to the secmon

Several of the intel platforms define the region reserved
for PCI memory resources in a location where it overlaps
with the MMIO (MCFG) region.
Using the memory map from mohon_peak as an example:
0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES

8. 0000000100000000-000000017fffffff: RAM
The ACPI table describing the space set aside for PCI memory
(not to be confused with the MMIO config space) is defined
as the region from BMBOUND (the top of DRAM below 4GB) to
a hardcoded value of 0xfebfffff. That region would overlap
the MMIO region at 0xe0000000-0xefffffff. For rangeley
the upper bound of the PCI memory space should be set
to 0xe0000000 - 1.
The MCFG regions for several of the affected chipsets are:
rangeley 0xe0000000-0xefffffff
baytrail 0xe0000000-0xefffffff
haswell 0xf0000000-0xf3ffffff

The ChromeOS machines employing vboot verfication require
different combinations of support:
1. When vboot verification starts.
2. Is the vboot code a separate stage or program?
3. If a separate stage, does the that vboot program (verstage) return
to the stage that loaded the verstage?
For the above, #1 is dependent on when to load/run vboot logic which
is orthogonal to #2. However, #3 is dependent on #2. The logic
to act on the combinations follows in subsequent patches.

The long term plan is to enable out of tree components to be

The DRAM configuration register, apart from holding the
device density and width also has a rudimentary address
mapping scheme. Currently this is set to the default
Bank/Row/Column. This means that the memory is segmented
into 8 chunks, each with a page detector. If all the
activity is in one section of memory then the other 7
page detectors could be idle.
Changing this to Row/Bank/Column would concatenate the
page detectors meaning that all 8 could be used by a
single initiator. This may not gain anything in a
synthetic bandwidth test but could yield extra performance
in a real world application or benchmark.

This patch fixes a bug in LPDDR3 initialization due to an incorrect
operator precedence assumption ( ?: does not bind stronger than | ). In
effect, instead of setting MR11[1:0] to 0b11 or 0b00 based on ODT, we're
unconditionally setting MR0[1:0] to 0b11. Thankfully, MR0[1:0] seems to
contain read-only bits so this might have not been a problem when ODT is
off (which is currently true for all LPDDR boards).
Also adding a redundant LPDDR_OP() around the 0 to make the intent
clearer and changing 3 and 0 to 0x3 and 0x0 to make it more obvious that
these are bit masks (right?).

BOARD_ID functionality is not what requires the GPIO lib,
but it is the mainboard specific implementations that do.
The option essentially says whether the SoC provides
<soc/gpio.h> (with the interface required by the common
GPIO code). Right now, x86 and Samsung's Exynos SOCs
don't have support for this interface.
So this should be selected by the SOC, not by
BOARD_ID_SUPPORT.

The code to calculate the RK3288 SPI controller's internal clock divisor
is wrong: it assumes that the divisor register was an "n-1" divisor when
it actually isn't (due to some misleading kernel code that was copied in

expected.
This patch fixes the calculation and changes all callers such that the

Using identity_map(), map the DRAM/SRAM regions to themselves (which
happens to be using KUSEG on urara).
The bootblock (which still runs in KSEG0) sets up the identity mapping
in bootblock_mmu_init() so that ROM/RAM stages can be loaded into the
KUSEG address range.
The stack and pre-RAM CBMEM console also remain in KSEG0 since we
don't really care about their physical addresses.

Found that any non-USB3.0 devices connected to type-C ports
(displayPort dongles) cause XHCI port to see connection which in turn
leads us to enter USB compliance mode.

The ipq806x UART is based on the same universal serial port which can
be also configured as i2c or SPI. Configuring it is not a trivial
task, so in case the kernel wants to use earlyprintk() the port needs
to be configured by the firmware.
Invoking uart_init() when the console is not enabled causes include
file collisions, which would require changes to more than 100 files.
Leaving this to another day, rearranging the ipq806x driver to be able
to invoke UART initialization function even when serial console is not

Originally ported QCA UART driver used hardware accessor macros where
both address and data were represented by 32 bit integers. Coreboot
uses macros where addresses are represented by pointers, this make the
code more robust, as accidental swap between address and data does not
go unnoticed.
This patch converts ipq806x UART driver to use coreboot accessors. It
relies on gcc void pointer arithmetic considering objects pointed at
by void pointers to be one byte in size. Also replacing spaces with
hard tabs where appropriate.

Add support for applying write protection to the MRC cache
region in SPI flash.
This is only enabled if there is write protect GPIO that is
set, and the flash status register reports that the flash
chip is currently write protected.
Then it will call out to a SOC specific function that will
enable write protection on the RW_MRC_CACHE region of flash.
The implementation is not quite as clean as I would like because
there is not a common flash protect interface across SOCs so
instead it relies on a new Kconfig variable to be set that will
indicate a SOC implements the function to protect a region of
SPI flash.

This is the intialization code specific to the Winbond
W972GG6JB-25 part using Synopsys DDR uMCTL and DDR Phy.
This is DDR2 initialization code only (currently present
on the bring up board). DDR3 initialization code will follow
for boards having DDR3 memory.
The programming procedure that is executed at power up to bring
up the uMCTL, PHY and memories into a state where reads and
writes to the memory can be performed is the following:
1. uPCTL (Universal DDR protocol controller) initialization
The timining registers TOGCNT1U, TINIT, TOGCNT100N and TRSTH
needed for driving the memory power-up sequence are programmed
as a function of the internal timers clock frequency.
Organization (memory chip specific) values are set
(column/bank/row address width and number of ranks), together
with other static values (latency, timing, power up configuration).
All these values are static, provided by the datasheet,
being determined by the memory type, size and frequency.
2. PHY initialization
The PHY is programmed with datasheet provided values,
specifying the initialization values for it to send to the
external memory (timing parameters).
Also, delay lines (DLL) and strength of drive pads are
calibrated (based on external conditions: temperature,
voltage, noise) and locked. After that, the PHY goes
through a trainig process (also dependent on the
current conditions at boot time) to establish precise
timing configuration between the DDR clock and DQS (data strobe)
and between DQS and DQ (data).
3. Memory power up
4. Switch from configuration state to access state.

Add a clock control driver to initialize the clock tree inside the
low-power audio subsystem. Depthcharge builds up on this to enable
audio function on storm.
The clock is hardcoded for 48KHz frame rate, two 16 bit channels.

This patch adds the necessary platform glue to allow the use of
software-driven I2C bit banging on the RK3288. This is just a debugging
feature that can be used to reproduce certain I2C failure cases.
Also fix Makefile verstage linking for the feature and add some new
rk3288 IOMUX macros as needed.
BRANCH=None
BUG=None
TEST=Added "CONFIG_SOFTWARE_I2C=y" to configs/config.veyron_jerry,
wrapped Jerry's bootblock and verstage in software_i2c_attach/detach()
calls, confirmed that both PMIC and TPM could be driven correctly with
software I2C driver. Tried out different combinations of
software_i2c_wedge_ack() and software_i2c_wedge_read() on the PMIC and
observed transfer results with the hardware controller after reboot...
the worst that would happen is that the first register read-modify-write
(DCDC_ILMAX) would fail to read, but all later transfers would be fine.
Since that register is written twice (due to current BUCK1 ramp
implementation) and is not terribily important anyway, I think we don't
need to worry about wedging problems.

Many ChromeOS devices use a GPIO to reset the system, in order to
guarantee that the TPM cannot be reset without also resetting the CPU.
Often chipset/SoC hardware watchdogs trigger some kind of built-in
CPU reset, bypassing this GPIO and thus leaving the TPM locked. These
ChromeOS devices need to detect that condition in their bootblock and
trigger a second (proper) reboot.
This patch adds some code to generalize this previously
mainboard-specific functionality and uses it on Veyron boards. It also
provides some code to add the proper eventlog entry for a watchdog
reset. Since the second reboot has to happen before firmware
verification and the eventlog is usually only initialized afterwards, we
provide the functionality to place a tombstone in a memlayout-defined
location (which could be SRAM or some MMIO register that is preserved
across reboots).

Turns out there are uses for memlayout regions not specific to vboot2.
Rather than add yet another set of headers for a single region, let's
make the vboot2 one common for chromeos.
