Commit c9b13594eb8d425e54a126b5c10e3f6fbc41528b removed the g_ prefix from
global variables, leaving the local "offset" variable shadowing the
global one. This commit partially reverts this by renaming one of the
occations and converting the flushing logic to work on the
global object.

The SPI flashes that support page programming mode had duplicated
the logic for writing in every driver. Add
spi_flash_cmd_write_page_program() and use the common implementation
to reduce code size that comes from duplication. The savings is
~2.5KiB per stage where the spi flash drivers are utilized.

The SST25VF064C supports page programming mode like other spi flash
parts in that there isn't an offset requirement. Remove this
check and single byte program because CMD_SST_BP (0x2) is the
same as page programming command. Lastly, for clariy purposes provide
a CMD_SST_PP to explicitly indicate page programming despite the
values (0x2) being the same as byte programming for the other parts.

According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.
How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

The MIPS architecture port has been added 5+ years ago in order to
support a Chrome OS project that ended up going nowhere. No other board
has used it since and nobody is still willing or has the expertise and
hardware to maintain it. We have decided that it has become too much of
a mainenance burden and the chance of anyone ever reviving it seems too
slim at this point. This patch eliminates all MIPS code and
MIPS-specific hacks.

Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.
int sum(size_t n) {
int arr[n];
...
}
This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],
AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
much _slower_ code (and more fragile code), than just using a fixed
key size would have done. [...] Anyway, some of these are definitely
easy to just fix, and using VLA's is actively bad not just for
security worries, but simply because VLA's are a really horribly bad
idea in general in the kernel.
This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

This patch adds support to read SPI flash in Dual SPI mode, where both
MISO and MOSI lines are used for output mode (specifically Fast Read
Dual Output (0x3b) where the command is still sent normally, not Fast
Read Dual I/O (0xbb) whose additional benefit should be extremely
marginal for our use cases but which would be more complicated to
implement). This feature needs to be supported by both the flash chip
and the controller, so we add a new dual_spi flag (and a new flags field
to hold it) to the spi_flash structure and a new optional xfer_dual()
function pointer to the spi_ctrlr structure. When both are provided,
Dual SPI mode is used automatically, otherwise things work as before.
This patch only adds the dual_spi flag exemplary to all Winbond and
Gigadevice chips, other vendors need to be added as needed.

All SPI flash chip drivers currently in coreboot use the generic read
functions (spi_flash_cmd_read_fast()/_slow()) as their read callback.
The only use case for specialized read callbacks we have left is with
specialized flash controllers like Intel fast_spi (which sort of
impersonate the flash chip driver by implementing their own probe
function).
This patch unifies the behavior for all normal flash drivers by making
the read callback optional and letting them all fall back to a default
read implementation that handles normal fast/slow reading. Most of the
drivers used to install the respective callback after checking
CONFIG_SPI_FLASH_NO_FAST_READ, but some hardcoded either slow or fast
writes. I have found no indications for why this is and spot-checked
datasheets for affected vendors to make sure they all support both
commands, so I assume this is just some old inaccuracy rather than
important differences that need preserving. (Please yell if you
disagree.)
Also take the opportunity to refactor some of the common spi_flash.c
code a bit because I felt there are too many nested functions that don't
really do enough on their own, and centralizing stuff a bit should make
it easier to follow the code flow. (Some of this is in preparation for
the next patch.)

Also fix an issue with building this code on MIPS due to lack of 64-bit
division primitives. (This means MIPS and arm32 board may display
incorrect results when reading more than 4MB in a single transfer, which
sounds very unlikely.)

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

Static scan-build indicates a possible invalid return from function
spi_flash_cmd_erase(). The root cause is because the scan believes it's
possible for offset to be above the end address in the first pass, thus
not setting a value for variable ret. Assign initial value of -1 to
variable ret to make checker happy.

Clean it up and add all flash chip drivers to postcar stage thereby.
There seem to be SPI controllers that don't need the individual
flash chip drivers. For those postcar support was added in b6b1b23
(console/flashconsole: Enable support for postcar). However for
SPI controllers that need the individual drivers (i.e. those with
CONFIG_SPI_FLASH_INCLUDE_ALL_DRIVERS=y), linking of the postcar
stage was broken.
For all other stages, the set of compilation units stays the same.

Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:
- Remove spi_xfer_two_vectors() which was fusing transactions to
accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
will trigger an error as these controllers can't support the api.

Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

drive the logic within spi_crop_chunk():
SPI_CNTRLR_DEDUCT_CMD_LEN
SPI_CNTRLR_DEDUCT_OPCODE_LEN

The spi_flash_cmd_read_fast() and spi_flash_cmd_read_slow() were just
passing full size buffers to the spi controller ops. However, the
code wasn't honoring what the spi controller can actually perform.
This would cause failures to read on controllers when large requests
were sent in. Fix this by introducing a
spi_flash_cmd_read_array_wrapped() function that calls
spi_flash_cmd_read_array() in a loop once the maximum transfer size is
calculated based on the spi controller's settings.

All coreboot stages using TPM start with the same sequence: check if
locality is claimed, if so, release it by writing 'active locality'
bit, then try claiming it.
This is actually not a proper procedure: section "5.5.2.3.1 Command
Aborts" of "TCG PC Client Platform TPM Profile (PTP) Specification
Level 00 Revision 00.430 Family 2" lists overwriting active locality
status bit as a means of triggering TPM command abort.
On top of that, none of the coreboot stages releases locality, it is
enough to claim it once when device starts booting.
In fact, locality being active when the device is in verstage is most
likely due to delayed TPM reset processing by the Cr50 TPM: reset is
an asynchronous event, and is processed once current command
processing completes.
The proper procedure is to wait if locality is active until it is
released (which will happen when Cr50 processes reset) and then
proceed to claim it. This needs to happen only during verstage, other
stages using TPM are guaranteed has been claimed earlier.

long enough to accommodate the (current) long crypto times. This would

requests, sends wrong register values in response to read requests.
This patch makes sure that the TPM driver does not proceed unless
proper value is read from the TPM device identification register.
