Daisuke Nojiri efddcfbb52 vboot2: separate verstage from bootblock
With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over
the bootblock, then exits to the romstage. this is necessary for some SOC
(e.g. tegra124) which runs the bootblock on a different architecture.

With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock.
Then, the bootblock loads the romstage over the verstage and exits to the
romstage. this is probably necessary for some SOC (e.g. rockchip) which does not
have SRAM big enough to fit the verstage and the romstage at the same time.

BUG=none
TEST=Built Blaze with USE=+/-vboot2. Ran faft on Blaze.

Note: This purposefully is probably broken in vendorcode/google/chromeos
as I'm just trying to set a base for dropping more patches in. The vboot
paths will have to change from how they are currently constructed.

Daisuke Nojiri 5799097be5 vboot2: read secdata and nvdata
This code ports antirollback module and tpm library from platform/vboot_reference.
names are modified to conform to coreboot's style.

The rollback_index module is split in a bottom half and top half. The top half
contains generic code which hides the underlying storage implementation.
The bottom half implements the storage abstraction.
With this change, the bottom half is moved to coreboot, while the top half stays
in vboot_reference.

TEST=Built with USE=+/-vboot2 for Blaze. Built Samus, Link.

Vadim Bendebury d36ef6a51d ipq806x: implement GPIO API
Add implementation of the GPIO API defined in src/include/gpiolib.h.
Also, clean up the GPIO driver, make it use pointers instead of
integers for register address.

This requires a touch in the SPI driver, where the CS GPIO is toggled
and in the board function where it enables USB interface.

Vadim Bendebury 9c9c336464 Generalize revision number calculation function
Some platforms use tertiary interpretation of GPIO input state to
increase number of distinct values represented by a limited number of
GPIOs. The three states are

- external pull down (interpreted as 0)
- external pull up (1)
- not connected (2)

This has been required by Nvidia devices so far, but Exynos and
Ipq8086 platforms need this too.

This patch moves the function reading the tertiary state into the
library and exposes the necessary GPIO API functions in a new include
file. The functions are still supposed to be provided by platform
specific modules.

The function interpreting the GPIO states has been modified to allow
to interpret the state either as a true tertiary number or as a set
two bit fields.

Since linker garbage collection is not happening when building x86
targets, a new configuration option is being added to include the new
module only when needed.

BUG=chrome-os-partner:30489
TEST=verified that nyan_big still reports proper revision ID.

Aaron Durbin 9ef9d85976 bootstate: use structure pointers for scheduling callbacks
The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.

In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

by loops in spi_xfer() which will break large transfers into smaller

Furquan Shaikh fbff908a74 coreboot classes: Add dynamic classes to coreboot
Provide functionality to create dynamic classes based on program name and the
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class and compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.

One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

This patch removes a chunk of romstage code from Tegra and all Nyan
boards that was supposed to enable some LCD power rails early, but never
really worked. The dev_find_slot() function can only find PCI devices,
which the CPU cluster is not. Since we're done with Nyan-RO and the
ramstage display code is fine as it is, there is no point in trying to
fix this... but we should remove it from ToT lest someone uses it as a
blueprint to add more dead code to future boards.

Aaron Durbin 44f465d21c tegra132: fix Rx FIFO underruns with slower SPI clock
The SPI controller operates on packets which can be variable
length up to 32-bit packets. It also has the ability to be
put in packed or unpacked mode w.r.t each packet. i.e. does
a single fifo register hold >= 1 packet. The current programming
uses 8-bit packets in unpacked mode which means 4 fifo slots
are used for a 32-bit DMA transfter. As the AHB can only operate
on a minimum of 32-bit bursts the triggers need to be programmed
correctly so that there is room for a full 32-bit DMA transaction.

Previously faster SPI clocks just made things magically work.

During the development of commit bde6d30 (x86: Change MMIO addr

and patterns tried. An intermediate pattern was the use of u32 pointers,
and division by sizeof(u32). Some of these did not get properly
changed to pointer types of length 1, causing a regression in
the Intel Ibex Peak SATA driver, fixed in commit 9b5f137
(Intel ibexpeak: Fix SATA configuration).

Other regressions of this pattern are fixed here. I audited all changes
to u32 types, and the other ones are safe.

Alexandru Gagniuc eb73a21882 soc/fsp_baytrail: Fix use of microcode-related Kconfig variables
SUPPORT_CPU_UCODE_IN_CBFS is a deprecated option now that all CPUs
with updateable microcode (except AGESA) load microcode from CBFS.
CPU_MICROCODE_ADDED_DURING_BUILD is a state variable that is set
based on user's choice in the microcode menu and should not be changed
directly.

Eliminate INCLUDE_MICROCODE_IN_BUILD variable, whose use directly
interferes with the microcode mechanism, remove selection of
CPU_MICROCODE_ADDED_DURING_BUILD, and do not depend
SUPPORT_CPU_UCODE_IN_CBFS on anything. This makes usage of the
microcode mechanism consistent with other CPUs in the tree.

This incorrect usage of the Kconfig variables was hiding the fact that
some of the microcode files present in fsp_baytrail/microcode_blob.c
were not present in the tree.

This patch is to perform software triggered RAM re-repair in

"RAM" actually refers to the CPU cache here (yeah, I know, but that's

done every time after applying power to the main CPU cores or their
cache may have random failures in some very rare cases.

Also, note that this file isn't built in coreboot proper, but is a

1) Save the pointer to the FSP HOB list to low memory at address 0x614.

This is the same location as CBMEM_RESUME_BACKUP - the two aren't used
in the same platform, so overlapping should be OK.  I didn't see any
documentation that actually said that this location was free to use, and
didn't need to be restored after use in S3 resume, but it looks like
the DOS boot vector gets loaded juat above this location, so it SHOULD
be ok.  The alternative is to copy the memory out and store it in cbmem
until we're ready to restore it.

2) When a request for the pointer to a CAR variable comes in, pass back
the location inside the FSP hob structure.

3) Skip the memcopy of the CAR Data.   The CAR variables do not
get transitioned back into cbmem, but used out of the HOB structure.

4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

Stefan Reinauer 77b1655d9b vboot2: add verstage
This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.

Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.

Joseph Lo 749559b1fb tegra124: fix and fine tune the warm boot code
We assume that the clock rate of SCLK/HCLK/PCLK was 408MHz which was same
as PLLP. But that is incorrect, BootROM had switched it to pllp_out2
with the rate 204MHz. So actually the warm boot procedure was running at
the condition of SCLK=HCLK=PCLK=pllp_out2 with the rate 204MHz.

And the CPU complex power on sequences were different with what we used
in kernel and Coreboot. Fix up the sequence as below.
* enable CPU clk
* power on CPU complex
* remove I/O clamps
* remove CPU reset

Update the time of the CPU complex power on function for record.
* power_on_partition(PARTID_CRAIL): 528 uSec
* power_on_partition(PARTID_CONC): 0 uSec
* power_on_partition(PARTID_CE0): 4 uSec

Finally, removing the redundant routine of a flow controller event with
(20 | MSEC_EVENT | MODE_STOP).

Vadim Bendebury 24a53dddb9 ipq806x: clean up UART driver tx_byte function
The driver as it was copied from u-boot provided a function to
transmit multiple characters in one invocation. This feature was not
ported to coreboot, there is no need to maintain the complexity when
only one character at a time is transmitted. It is also very desirable
to get rid of a 1024 byte array allocated on the stack.

The array was necessary to allow to convert multiple newline
characters in the transmit data flow into two character sequences
CRLF. Now just a single word is enough to keep one or two characters
to transmit.

[EDIT km: newline translation is now part of printk]

Vadim Bendebury dffd892e47 ipq8064: modify SPI controller driver to work in coreboot
A typical SPI operation consists of two phases - command and data
transfers. Command transfer is always from the host to the chip (i.e.
is going in the 'write' direction), data transfer could be either read
or write.

We don't want the receive FIFO to be operating while the command phase
is in progress. A simple way to keep the receive FIFO shut down is to
not to enable it until the command phase is completed.

Selective control of the receive FIFO allows to consolidate the
receive and transmit functions in a single spi_xfer() function, as it
happens in other SPI controller drivers.

The FIFO FULL and FIFO NOT EMPTY conditions are used to decide if the
next byte can be written or received, respectively. While data is
being received the 0xFF bytes are transmitted per each received byte,
to keep the SPI bus clocking.

The data structure describing the three GSBI ports is moved from the
.h file into .c file. A version of the clrsetbits macro is added to
work with integer addresses instead of pointers.

BUG=chrome-os-partner:27784
TEST=not yet, but with the res of the changes the bootblock loads and
     starts the rombase section successfully.

The original commit:
ipq8064: make UART driver work in bootblock

This patch it the last one in the chain adapting the ipq9064 UART
driver for use in coreboot. A new config option
(CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of
the driver.

The previously introduced uart_wrapper.c is now included in the build
to provide the console driver structure used by ramstage.

Necessary configuration options are added to allow use of UART in the
bootblock.

Julius Werner 83d1ba7e3d tegra: i2c: Add a timeout to I2C bit clear recovery mechanism
Our tests with the I2C bit clear mechanism (recovering from "lost
arbitration" errors) show that the bit clear hardware does not work
correctly in some situations. When a wedged slave device tries to send
more than one 0-to-1-to-0 transition to the host (e.g. leftover bits
from an aborted read), the controller never transitions the BC_ENABLE
bit back to zero.

This patch adds a long timeout to the bit clear code that waits for
register transitions as a safeguard. This way, We will still eventually
exit the function (probably followed by a reboot). Our tests show that
this will recover from all conditions after at most a few reboots.

Julius Werner 37d7ac8b5b i2c: Add software_i2c driver for I2C debugging and emulation
This patch adds I2C emulation in software through raw toggling of the
SDA/SCL lines. Platforms need to provide bindings to toggle their
respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs,
currently only enabled for Tegra).

This is mostly useful as a debugging feature, to drive unusual states on
a bus and closely monitor the device output without the need of a bus
analyzer. It provides a few functions to "wedge" an I2C bus by aborting
a transaction at certain points, which can be used to test if a system
can correctly recover from an ill-timed reboot. However, it can also
dynamically replace the existing I2C transfer functions and drive
some/all I2C transfers on the system, which might be useful if a driver
for the actual I2C controller hardware is not (yet) available.

Based on original code by Doug Anderson <dianders@chromium.org> and
Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded
controller project.

Vadim Bendebury 0b341b341d ipq/arm: Redesign hooks for bootblock
The following patches had to be squashed
to properly build all the different ARM boards.

ipq8064: storm: re-arrange bootblock initialization

The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.

As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.

Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

arm: Redesign mainboard and SoC hooks for bootblock

This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.

Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.

Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

Tom Warren bb932c56f0 nyan*: I2C: Implement bus clear when 'ARB_LOST' error occurs
This is a fix for the 'Lost arb' we're seeing on Nyan* during
reboot stress testing. It occurs when we are slamming the
default PMIC registers with pmic_write_reg().

Currently, I've only captured this a few times, and the bus
clear seemed to work, as the PMIC writes continued (where
they'd hang the system before bus clear) for a couple of regs,
then it hangs hard, no messages, no 2nd lost arb, etc. So
I've added code to the PMIC write function that will reset the
SoC if any I2C error occurs. That seems to recover OK, i.e. on
the next reboot the PMIC writes all go thru, boot is OK, kernel
loads, etc.

For the SMM case spi_init() is called during the finalize stage in

Gabe Black cdb61a6f5d i2c: Replace the i2c API.
The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.

Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.

The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

To ensure that the command1 write which sets the "go" bit completes before
other reads to the device. Otherwise, there's a race condition where those
register values might still have their values from the last transfer. With
different SPI clock frequencies, that could lead to spi_delay being told there
were negative bytes still to send. Its expected delay would wrap to a negative
value, that was passed to udelay, and the system would sit there for 4 seconds
not doing anything.

Gabe Black e5b21274bd tegra124: A couple clock fixes.
This fixes two problems with the clock configuration on tegra124. First, the
macro which set up the i2c clocks tried to account for the fact that the i2c
divisor's lsb represents 1.0 where it normally represents 0.5 by multiplying
the target frequency by 2. That doesn't work, unfortunately, because the
divisor is actually n + 1, and what n + 1 means depends on where the one's
place is in the divisor.

Also, when calculating the divisor, the standard C division operator uses
truncation to deal any remainder which tends to make the divisor smaller. That
has the effect of making the output frequency higher than what was requested.
Since it's usually safer to undershoot a frequency than overshoot it, this
change makes those divisions round up instead.

Finally, the hand tuned temporary UART clock configuration was adjusted so
that it still ends up with the same divisor. Without that, very early output
from the bootblock is garbled, specifically the coreboot welcome banner,
build timestamp, etc.

BUG=chrome-os-partner:27220
TEST=Built and booted on nyan. Used a logic analyzer to verify that the TPM
i2c bus ran at 400KHz instead of 660KHz, and that the divisor was the expected
value. Measured boot time with and without EFS and verified that there was no
change. Spot checked the output for errors and verified that none of the
bootblock output was garbled.

Had to add the stdlib.h from 89ed6c that hadn't been merged correctly.

Gabe Black 967058f807 spi: Factor EC protocol details out of the SPI drivers.
The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.

When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

BUG=None
TEST=Built and booted on pit. Built and booted on nyan. In both cases,
verified that there were no error messages from the SPI drivers or the EC
code.
BRANCH=None

Martin Roth a0a71b046a fsp platfoms: add prototype & consolidate main entry-point
- In '-ffreestanding' main() is just as any other function and so
it needs a type-signature. Fixes a clang warning.

- Bay Trail and Rangeley have the updated romstage.c with the code
moved into the chipset, put the prototype in romstage.c.

- The sandybridge code has not been updated, so the prototype
for it goes into chipset_fsp_util.h, next to the prototype for
romstage_main_continue.

- Correct the return value of baytrail main() from void * to void
and remove the unnecessary asmlinkage tag. I'm surprised that this
didn't generate a warning...

annoying.  Moving the creation of the MCRS object to outside of the
_CRS method and referencing it from there solves this problem.

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.

Julius Werner 7c6e489b23 arm: Put assembly functions into separate sections
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.

Julius Werner fd9defc0ca arm: Redesign, clarify and clean up cache related code
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.

Julius Werner 25a282dabc arm: Thumb ALL the things!
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).
