Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.
Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).
Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

Commit 257aaee9e3a (arm: Add bootblock_mainboard_early_init() for
pre-console initialization) inadvertently moved the timer initialization
after console initialization for IPQ806x, which is apparently not a good
idea for this platform. This patch solves the issue by moving
init_timer() to bootblock_mainboard_early_init(), which is the new hook
explicitly provided to perform pre-console tasks.

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.

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.

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).

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.

The current spi_xfer() function sets the count in hardware and then
loops while waiting for the requested number of bytes to be sent or
received. However, the number of bytes to be transferred may exceed
the maximum count that can be programmed into the controller.
This patch re-factors spi_xfer() to split the low-level FIFO handling
portions for transmit/receive into their own functions to be called
by loops in spi_xfer() which will break large transfers into smaller
ones.

This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e
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_.
TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

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]

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 patch from chromium was a bit of a mishmash.
Between that, rebasing and using the coreboot.org UART infrastructure,
the patch has changed a bit from the original. It seems reasonable to
keep these changes together.
- build in the ipq UART and turn on bootblock console
- sets LPAE and ROM header address
- adds cpd.c to storm
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.

These patch modifies .h files to match the coreboot API. A few more
significant changes are:
- UART specific fields removed from common board structure in cdp.h.
These fields are set at compile time in u-boot (where this
structure comes from), they will be set in a different structure in
the UART driver in an upcoming patch.
- an inline wrapper is added in gpio.h to provide GPIO API the UART
driver expects.
- the ipq_configure_gpio() is passed the descriptor placed in ro data.

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.
