This change switches all mainboard vendors and mainboards
to be autoincluded by Kconfig, rather than having to be mentioned
explicitly.
This means, vendor and mainboard directories are becoming more
"drop in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.
The long term plan is to enable out of tree mainboards / components
to be built with a given coreboot version (given that the API did
not change)

This patch fixes a bug that caused non-x86 boards to use the poor man's
assert() version with a lot more instructions per invocation and
hexadecimal line numbers in __PRE_RAM__ environments. This was really
just an oversight in the ARM port... even x86 uses a proper printk() in
most cases (those with CAR) and there's no reason not to do so on the
generally even more flexible SRAM-based architectures.
Additionally, it adds a new Kconfig option to make failed assertions and
BUG() calls halt again. This seems to have been the original intention,
but was commented out once out of fear that this might prevent
production systems from booting. It is still a useful debugging feature
though (since otherwise assertions can easily just scroll past and get
overlooked), so the user should be able to decide the this based on his
needs.
(Also changed error messages for both to include the word "ERROR", since
grepping for that is the most sophisticated way we currently have to
detect firmware problems. Some automated Chromium OS suspend tests check
for that.)

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.

Storm devices' recovery button is overloaded. Pressing it when the
system is running is supposed to reset the device. To trigger recovery
mode the button must be held pressed for at least 5 seconds after
reset.
Currently interpreting the recovery button state is the responsibility
of the board (vboot gets a consolidated state, which is a combination
of several conditions), so the simplest way to implement this feature
is to make the board follow the recovery button state.
In case the button is not pressed when it is first sampled, its state
is saved immediately and no recovery request is reported. In case the
button is pressed when it is first sampled, the board code keeps
polling it up to 5 seconds and acts accordingly.

the worst that would happen is that the first register read-modify-write

Since that register is written twice (due to current BUCK1 ramp

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).

This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
allow multiple CBFS instances in the bootrom.
When the new option is enabled, the code running on the target
controls which CBFS instance is used. Since all other then header CBFS
structures use relative addressing, the only value which needs
explicit setting is the offset of the CBFS header in the bootrom.
This patch adds a facility to set the CBFS header offset. The offset
value of zero means default. i.e. the CBFS initialization code still
discovers the offset through the value saved at the top of the ROM.

Instead of adding a new driver for these controllers, it is better to

We've traditionally tucked the framebuffer at the end of memory (above
CBMEM) on ARM and declared it reserved through coreboot's resource
allocator. This causes depthcharge to mark this area as reserved in the
kernel's device tree, which may be necessary to avoid display corruption
on handoff but also wastes space that the OS could use instead.
Since rk3288 boards now have proper display shutdown code in
depthcharge, keeping the framebuffer memory reserved across the handoff
(and thus throughout the lifetime of the system) should no longer be
necessary. For now let's just switch the rk3288 implementation to define
it through memlayout instead, which is not communicated through the
coreboot tables and will get treated as normal memory by depthcharge.
Note that this causes it to get wiped in developer/recovery mode, which
should not be a problem because that is done in response to VbInit()
(long before any images are drawn) and 0 is the default value for a
corebootfb anyway (a black pixel).
Eventually, we might want to think about adding more memory types to
coreboot's resource system (e.g. "reserved until kernel handoff", or
something specifically for the frame buffer) to model this situation
better, and maybe merge it with memlayout somehow.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
