Julius Werner 55009af42c Change all clrsetbits_leXX() to clrsetbitsXX()
This patch changes all existing instances of clrsetbits_leXX() to the
new endian-independent clrsetbitsXX(), after double-checking that
they're all in SoC-specific code operating on CPU registers and not
actually trying to make an endian conversion.

This patch was created by running

 sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g'

across the codebase and cleaning up formatting a bit.

Julius Werner 1c37157218 mmio: Add clrsetbitsXX() API in place of updateX()
This patch removes the recently added update8/16/32/64() API and
replaces it with clrsetbits8/16/32/64(). This is more in line with the
existing endian-specific clrsetbits_le16/32/64() functions that have
been used for this task on some platforms already. Rename clrsetbits_8()
to clrsetbits8() to be in line with the new naming.

Keep this stuff in <device/mmio.h> and get rid of <mmio.h> again because
having both is confusing and we seem to have been standardizing on
<device/mmio.h> as the standard arch-independent header that all
platforms should include already.

Also sync libpayload back up with what we have in coreboot. (I'm the
original author of the clrsetbits_le32-definitions so I'm relicensing
them to BSD here.)

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

a mainenance burden and the chance of anyone ever reviving it seems too
slim at this point. This patch eliminates all MIPS code and

Nico Huber e79595def5 libpayload: Use interrupt transfers for USB hubs
In interactive payloads, the USB stack's poll procedure is implicitly
called from the UI loop. Since all USB control transfers are handled
synchronously, polling hubs with these slows the UI significantly down.

So switch to interrupt transfers that are done asynchronously and only
perform control transfers when the hub reported a status change.

We use the interrupt endpoint's max packet size instead of the theo-
retical transfer length of `(bNrPorts + 1) / 8` as Linux' code mentions
hubs that return too much data.

Julius Werner 277498c283 libpayload: usbmsc: Factor out usb_msc_force_init() function
We're planning to have a use case with a custom USB device that
implements the USB mass storage protocol on its bulk endpoints, but does
not have the normal MSC class/protocol interface descriptors and does
not support class-specific control requests (Get Max LUN and Bulk-Only
Reset). We'd like to identify/enumerate the device via
usb_generic_create() in our payload but then reuse all the normal MSC
driver code. In order to make that possible, this patch factors a new
usb_msc_force_init() function out of usb_msc_init() which will
initialize an MSC device without checking its descriptors. It also adds
some "quirks" flags that allow devices registered this way to customize
behavior of the MSC stack.

Julius Werner 182fea717e libpayload: usbmsc: Skip zero-length packets at end of data
Some broken USB mass storage devices send another zero-length packet at
the end of the data part of a transfer if the amount of data was evenly
divisible by the packet size (which is pretty much always the case for
block reads). This packet will get interpreted as the CSW and screw up
the MSC state machine.

This patch works around this issue by retrying the CSW transfer when it
was received as exactly 0 bytes. This is the same mitigation the Linux
kernel uses and harmless for correctly behaving devices. Also tighten
validation of the CSW a little, making sure we verify the length before
we read any fields and checking the signature in addition to the tag.

Julius Werner db7f6fb752 Add buffer_to/from_fifo32(_prefix) helpers
Many peripheral drivers across different SoCs regularly face the same
task of piping a transfer buffer into (or reading it out of) a 32-bit
FIFO register. Sometimes it's just one register, sometimes a whole array
of registers. Sometimes you actually transfer 4 bytes per register
read/write, sometimes only 2 (or even 1). Sometimes writes need to be
prefixed with one or two command bytes which makes the actual payload
buffer "misaligned" in relation to the FIFO and requires a bunch of
tricky bit packing logic to get right. Most of the times transfer
lengths are not guaranteed to be divisible by 4, which also requires a
bunch of logic to treat the potential unaligned end of the transfer
correctly.

We have a dozen different implementations of this same pattern across
coreboot. This patch introduces a new family of helper functions that
aims to solve all these use cases once and for all (*fingers crossed*).

Jacob Garber 768db4f5ca libpayload/libc: Correct strlcat return value
The documented return value for strlcat is horribly wrong, as is the
return value itself. It should not return the number of appended bytes,
but rather the length of the concatenated string. From the man page:

    The strlcpy() and strlcat() functions return the total length of the
    string they tried to create. For strlcpy() that means the length of
    src. For strlcat() that means the initial length of dst plus the
    length of src. While this may seem somewhat confusing, it was done
    to make truncation detection simple.

This change is more likely to fix existing code than break it, since
anyone who uses the return value of strlcat will almost certainly rely
on the standard behaviour rather than investigate coreboot's source code
to see that we have a quirky version.

Nico Huber 21bfc9f99b Revert "libpayload: Reset PS/2 keyboard"
Documentation is scarce on the matter, however the related coreboot
code suggests that after the ACK, the keyboard also sends the result
of the self test (passed/failed). It looks like this result is never
consumed here, probably resulting in further confusion for later com-
mands.

Let's revert this for now (if it's not too late for the 4.10 release)
and break things later again. IMHO, due to the fact that there are
dozens of different keyboard controller and keyboard implementations
and no accurate specification followed, such changes should be tested
on a lot of hardware before merge.

This reverts commit a99ed13e33.
This reverts commit 7ae606f57f.

Furquan Shaikh a99ed13e33 libpayload/i8042/keyboard: Fix return value check for keyboard_cmd

keyboard and check the return value of keyboard_cmd() to compare

ACK and returns 1 or 0 based on whether ACK is received.

This change fixes the check introduced by CB:32951 to compare against

prints consistent in case of failure.

Paul Menzel 7ae606f57f libpayload: Reset PS/2 keyboard
Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or
GRUB pressing keys does not give the expected results.

For example, pressing F1 gives the character 24 translated to scan code
6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU
Q35.

The problem is not reproducible using the payload directly, that means
without SeaBIOS or GRUB. The problem seems to be, that those have already
initialized the PS/2 controller and AT keyboard.

Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to
be reset. That seems to fix the issue, when the keyboard was initialized
before.

TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary
payload. Run

    qemu-system-i386 -M q35 -L /dev/shm -bios build/coreboot.rom -serial stdio

press 3 to select the coreinfo payload, and verify that the keys F1 and
F2 are working.

Same with coreinfo loaded from GRUB on the ASRock E350M1.

Julius Werner d371cf3336 Make common macros double-evaluation safe
I just got hit by a double-evaluation bug again, it's time to attempt
to fix this once more. Unfortunately there are several issues that don't
make this easy:

 - bitfield variables don't support typeof()
 - local macro variables that shadow others trigger -Werror=shadow
 - sign warnings with integer literal and unsigned var in typeof-MIN()
 - ({ statement expressions }) can not be used outside functions
 - romcc doesn't support any of the fancy GCC/clang extensions

This patch tries to address all of them as far as possible with macro
magic. We don't have the technology to solve the bitfield and
non-function context issues yet (__builtin_choose_expr() still throws a
"no statement expression outside a function" error if it's only in the
branch that's not chosen, unfortunately), so we'll have to provide
alternative macros for use in those cases (and we'll avoid making
__ALIGN_MASK() double-evaluation safe for now, since it would be
annoying to do that there and having an alignment mask with side
effects seems very unlikely). romcc can continue using unsafe versions
since we're hopefully not writing a lot of new code for it. Sign
warnings can be avoided in literal/variable comparisons by always using
the type of the variable there. Shadowing is avoided by picking very
explicit local variable names and using a special __COUNTER__ solution
for MIN() and MAX() (the only ones of these you're likely to nest).

Also add DIV_ROUND_UP() to libpayload since it's a generally quite
useful thing to have.

Julius Werner 78134b0ccd libpayload: strtoull: Fix edge case bug with *endptr
strtoull() can optionally take a second pointer as an out-parameter that
will be adjusted to point to the end of the parsed string. This works
almost right, but misses two important edge cases: firstly,when the
parsed string is "0", the function will interpret the leading '0' as an
octal prefix, so that the first actually parsed digit is already the
terminating '\0' byte. This will cause the function to early abort,
which still (correctly) returns 0 but doesn't adjust *endptr.

The early abort is pointless anyway -- the only other thing the function
does is run a for-loop whose condition is the exact inverse (so it's
guaranteed to run zero iterations in this case) and then adjust *endptr
(which we want). So just take it out. This also technically corrects the
behavior of *endptr for a completely invalid string, since the strtoull
man page says

> If there were no digits at all, strtoul() stores the original value of
> nptr in *endptr (and returns 0).

The second issue occurs when the parsed string is "0x" without another
valid digit behind it. In this case, we will still jump over the 0x
prefix so that *endptr is set to the first byte after that. The correct
interpretation in this case is that there is no 0x prefix, and instead a
valid 0 digit with the 'x' being invalid garbage at the end. By not
skipping the prefix unless there's at least one valid digit after it, we
get the correct behavior of *endptr pointing to the 'x'.

If keys are pressed at boot some keyboard controllers will not
properly respond with an ACK to commands, which results in the
keyboard_init function aborting before it adds the keyboard to the
input device list.

This same keyboard controller will manage to properly return keyboard
data when keys are pressed later, so it is possible for it to be
functional in the payload even if it does not respond properly to
every command during initialization.

In order to allow payloads to use the keyboard when this happens a
new Kconfig option is added to ignore the keyboard ACK response and
always add the keyboard to the input device list.  This option is
disabled by default and must be enabled by the specific boards that
need it.

how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state

useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.

This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).

Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

contemporary "Google LLC."

While at it, also ensure consistency in the LLC variants (exactly one

"Google Inc" does not need to be touched, so leave them alone.

I need to setup the APIC timer to fire interrupts. I would like to reuse
the existing interrupt table. So I extended it to support user defined

any additional build time configuration.

I'm going to deprecate exception_install_hook and remove it in a follow
up. It will be replaced with set_interrupt_handler. This way the
exception lookup does not have to manage a list of callbacks, or have to
worry about the order they are processed.

In order to support booting a GNU/Linux payload on non x86, the FIT format
should be used, as it is the defacto standard on ARM.
Due to greater complexity of FIT it is not converted to simple ELF format.

Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'.
The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.

Starting at this point a CBFS payload/ can be either of type FIT or SELF.

Tested on Cavium SoC.

Julius Werner 3faa2c802e libpayload: usbhid: Zero-initialize all parts of usbhid instance struct
The USBHID driver zero-initializes some but not all of the fields in its
usbhid_inst_t structure. This is a problem because under some
circumstances, some of the uninitialized fields may be read and lead to
incorrect behavior. Some (broken) USB keyboards keep sending reports
that contain all zeroes even when they have no new keys... these usually
get silently ignored, but if the usbhid_inst_t structure is in an
inconsistent state where 'previous' is zeroed out but 'lastkeypress'
is non-zero because it wasn't properly initialized, these reports will
be interpreted as keyrepeats of the bogus 'lastkeypress'. This patch
changes the code to just xzalloc() the whole structure so we won't have
to worry about initialization issues anymore.

bebitenc() just runs a downward loop over the same body as lebitenc().
That doesn't give you a byte-swapped result, it gives you the same final
value, just starting from the other side to fill it in. (Also, it
confused i++ and i--, so it really gives you a compiler error.)

The correct code needs to have the array index inverted relative to the
bit shift index to produce a big endian result.

Marshall Dawson 148a7a60d8 libpayload: Fix unaligned buffer logic in default_memset
Fix an issue when setting an unaligned buffer where n is less
than the difference of the rounded up pointer and the pointer.
This was identified where n=1 was passed.  n was decremented
once, as expected, then decremented again after the while()
evaluated to false.  This resulted in a new n of 4GB.

Julius Werner d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)

The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

Mathias Krause 901efea8ab libpayload: x86/exec - fix return value passing
The pointer to write the return value to is in %ecx, not %eax. Writing
to (%eax) leads to memory corruptions as %eax holds the return value,
e.g. would write zero to address zero for a "successful" returning
payload.

According to coreboot’s payload API [1] the magic value passed to the
payload should be 0x12345678, not 12345678. Fix that.

Patrick Georgi b144a34c60 libpayload: fix build
When .xcompile doesn't already exist, building libpayload fails because
the CC variable (et al) remain empty since .xcompile is only included
after the variables coming from there are evaluated.

It takes a long time for no gain: We don't need to update the
submodules, we don't need to fetch the revision, we don't need to find
the compilers, when all we want to do is to manipulate the .config file
or clean the build directory.

Coverity considers this a copy&paste error, and maybe it is. In any
case, it makes sense to check the variable that (if the condition is
true) is changed, and the values are the same before that test, so the
change is harmless.
