Raul E Rangel d4fec689fd cbmem: Sort timestamp entries
If the timestamp entries are added out of order, the duration
calculation will be wrong.

AGESA collects timestamp data through all the stages. Then in AmdInitPost
it asks for a buffer to write TP_Perf_STRUCT into. agesawrapper will then
take the data and call timestamp_add on each entry. This results in
the entries being out of order.

TEST=Built firmware for grunt that manually added entries and then ran
cbmem -t/-T to verify the entries were in the correct order.

Aaron Durbin 46300aa2ce util/cbmem: be explicit about memory map sizes
The cbmem utility has inherited some workarounds that originated
from the default 1 MiB mapping always working. This 1 MiB mmap
won't necessarily succeed if the 1 MiB encroaches on a subsequent
memory range that has different cacheability.

To fix this, map in only 4 KiB when the table size is not known which is
the case for any forwarding entry or any low table entries on x86. That
smaller mapping is then searched for a valid header. Once a valid header
is found the full table is mapped and parsed allowing a forwarding entry
to take precedence.

Lastly, the lbtable is kept mapped in such that other operations can
just operate on mapping that was previously parsed.

In order to allow multiple in-flight mappings a struct mapping was
added which caused the ripple within the code. However, there shouldn't
be any more reasons for putting weird heuristics for when to fail. If
the tables are bad then it's very much possible that mappings will fail.
Retrying when the exact sizes are already known won't fix those issues.

Julius Werner d906bb68c3 cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logs
The 'cbmem -1' flag that cuts off console output before the last boot
will ignore content from earlier stages if it was truncated due to lack
of pre-CBMEM console space. This patch makes the "log truncated" message
more specific and adds it as an additional cut-off marker to 'cbmem -1'
to counteract that problem.

Also raise the log level of the coreboot banner one step to BIOS_NOTICE
to make it more likely to be included in the output for 'cbmem -1' to
find. (I believe NOTICE is reasonable but I wouldn't want to go as far
as WARN which should be reserved for actual problems. Of course this is
not ideal, but then again, our whole log-level system really isn't... it
would be better if we could make it always print a banner to the CBMEM
console without affecting the UART at the same time, but that would
require a larger amount of work.)

Aaron Durbin 7ad44eed08 util/cbmem: mmap underflow on low addresses
There is code to adjust the mapping down if a mmap fails
at a physical address. However, if the address is less
than the page size of the system then the physical offset will
underflow. This can actually cause a kernel panic on when
operating on /dev/mem.

The failing condition happens when the requested mapping at 0
fails in the kernel. The fallback path is taken and page size
is subtracted from 0 making a very large offset. The PAT code
in the kernel fails with a BUG_ON in reserve_memtype() checking
start >= end. The kernel needs to be fixed as well, but this
fallback path is wrong as well.

Julius Werner b7b64a9f68 cbmem: Add new command line flag to dump console for one boot only
Even though the persistent CBMEM console is obviously awesome, there may
be cases where we only want to look at console output from the last boot.
It's easy to tell where one boot ends and another begins from the banner
message that coreboot prints at the start of every stage, but in order
to make it easier to find that point (especially for external tools),
let's put that functionality straight into the cbmem utility with a new
command line flag. Use the POSIX/libc regular expression API to find the
banner string for maximum compatilibity, even though it's kinda icky.

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).

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.

For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on

Julius Werner 4f7a3614cd chromeos: Add timestamps to measure VPD read times
This patch adds three timestamps to coreboot and the cbmem utility that
track the time required to read in the Chrome OS Vital Product Data
(VPD) blocks (RO and RW). It's useful to account for these like all
other large flash accesses, since their size is variable.

<..etc..>

(2) With this patch, new command line arg "rawdump" or "-r" will be
added to cbmem

user can grab the ID with "cbmem -l" and execute "cbmem -r <ID>" to get
raw dump of cbtable for the <ID> in interest.

This change is needed to get MMA results data from cbtable. Coreboot
stores the MMA results in cbmem. Separate post processing scripts uses
cbmem utility to get the these data.

This feature in the cbmem tool can also help debugging some issues where
some specific ID of cbtable needs examination.

Aaron Durbin c49014e750 timestamp: add tick frequency to exported table
Add the timestamp tick frequency within the timestamp table so
the cbmem utility doesn't try to figure it out on its own. Those
paths still exist for x86 systems which don't provide tsc_freq_mhz().
All other non-x86 systems use the monotonic timer which has a 1us
granularity or 1MHz.

One of the main reasons is that Linux is reporting
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true
turbo frequency on turbo enables machines. This change also fixes
the p-state values honored in cpufreq for turbo machines in that
turbo p-pstates were reported as 100MHz greater than nominal.

It's helpful to know the base_time (1st timestamp) in the
timestamp table because it provides more information like
the accumulated time before the first timestamp was recorded.

In order to maximize this information report the base time
as an entry that is printed. It's called '1st timestamp'.
The implementation turns all the timestamp entries into absolute
times so one can observe both absolute and relative time for
each marker.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Julius Werner a7d924412a timestamps: You can never have enough of them!
Now that we have timestamps in pre-RAM stages, let's actually make use
of them. This patch adds several timestamps to both the bootblock and
especially the verstage to allow more fine-grained boot time tracking.

Some of the introduced timestamps can appear more than once per boot.
This doesn't seem to be a problem for both coreboot and the cbmem
utility, and the context makes it clear which operation was timestamped
at what point.

Also simplifies cbmem's timestamp printing routine a bit, fixing a
display bug when a timestamp had a section of exactly ",000," in it
(e.g. 1,000,185).

BRANCH=None
BUG=None
TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show
up and contained sane values. Booted Storm (no timestamps here since it
doesn't support pre-RAM timestamps yet).

Aaron Durbin b58f9e3a30 cbmem: stop assuming 1MiB of memory can be mapped
The default mapping size is 1MiB of ram. However, not
all systems allow 1MiB of memory to mapped depending on
the kernel's memory map. Therefore, be explicit about
the sizes to mmap().

The only path that wasn't cleaned up was the coverage path
as that needs to handle dynamic cbmem. The correct way to
fix that is to add a global like the timestamps that is set
while parsing cbtable.

Julius Werner 337de4c0e5 cbmem: Add support for new 'coreboot' compatible device tree binding
This patch brings the cbmem utility in line with the recent change to
coreboot's device tree binding. Since trying to find the right node to
place this binding has been so hard (and still isn't quite agreed upon),
and because it's really the more correct thing to do, this code searches
through the device tree for the 'coreboot' compatible property instead
of looking up a hardcoded path. It also provides bullet-proof
'#address-cells' handling that should work for any endianness and size.

BUG=chrome-os-partner:29311
TEST=Ran cbmem -c and cbmem -t on Nyan_Big. Also straced the to make
sure everything looks as expected. 'time cbmem -t' = ~35ms shows that
there is no serious performance problem from the more thorough lookup
code.

Commit b4b9eb39 (x86: provide infrastructure to backup default SMM

did not add its name `SMM BACKUP` to the utility `cbmem`, causing the
following output, when running `cbmem` on a system making
use of `BACKUP_DEFAULT_SMM_REGION`.

Fix that by adding the name `SMM BACKUP` to the struct
