Julius Werner 540a98001d printf: Automatically prefix %p with 0x
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.

Julius Werner 879ea7fce8 endian: Replace explicit byte swapping with compiler builtin
gcc seems to have some stupid problem with deciding when to inline byte
swapping functions (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92716).
Using the compiler builtin instead seems to solve the problem.

(This doesn't yet solve the issue for the read_be32()-family of
functions, which we should maybe just get rid of at some point?)

Julius Werner 2e0bca011a arm64: Bump exception stack size to 2KB
To avoid trampling over interesting exception artifacts on the real
stack, our arm64 systems switch to a separate exception stack when
entering an exception handler. We don't want that to use up too much
SRAM so we just set it to 512 bytes. I mean it just prints a bunch of
registers, how much stack could it need, right?

Quite a bit it turns out. The whole vtxprintf() call stack goes pretty
deep, and aarch64 generally seems to be very generous with stack space.
Just the varargs handling seems to require 128 bytes for some reason,
and the other stuff adds up too. In the end the current implementation
takes 1008 bytes, so bump the exception stack size to 2K to make sure it
fits.

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.)

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.

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.

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
CB:32951 ("libpayload: Reset PS/2 keyboard") added a call to reset
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

error messages for all failed commands in keyboard_init() to make the
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.
