When flash regions are protected, erase could incorrectly erase regions
which were meant to be protected by requesting the correct size but
using an erase opcode with coarser granularity than desired (for
instance using a 16-byte erase command while attempting to erase only 8
bytes).
This fixes that by exchanging the nesting of the loops over erase blocks
and flash regions.
Old:
- Select erasefns
- Loop over blocks to erase for each selected erasefn
- Loop over programmer flash regions within erase block
- Erase regions (may fail since selected erasefn will be
too big if flash region is smaller than erase block)
New:
- Loop over programmer flash regions within erase block
- Select erasefns within programer flash region
- Loop over blocks to erase for each selected erasefn
- Erase regions
Eraser selection and erasing has also been factored out into a helper
function to manage nesting depth.
TEST=New test cases pass, whereas some of them fail without the changes
to erasure_layout.c

get_flash_region() emits a struct flash_region, which uses chipoff_t for
the start and end addresses of a region. chipoff_t is defined as a valid
flash address, so it was wrong to be setting the end address to start +
len; this is clearly wrong in the case where there is a single region
because setting end to the flash size generates an address that is
beyond the end of the chip (due to zero-indexing).
This changes the one actual implementation of .get_region in ichspi.c to
use inclusive upper bounds, and corrects all callers of
get_flash_region() to treat the upper bounds as inclusive. Overall this
reduces complexity slightly by removing more downward adjustments by 1
than it needs to add upward adjustments.
TEST=on yaviks, `flashrom -V -x` prints equivalent messages about
"x region (0xZZZZ..0xZZZZ) is readable" before and after this
patch.

Although chipoff_t is fairly clearly documented on its own, it seems
fairly frequent that developers will treat the end address of a flash
region as an exclusive upper bound rather than the inclusive one it
should be; for example CB:82496 fixes an incorrect use that affected
multiple sites, and CB:73571 stemmed from a similar cause. Add a
clarifying comment to call attention to this, to help programmers avoid
making similar mistakes in the future.

Waiting a full second is a very long time, especially when
default_delay() chooses to busy-loop. This code has been around for a
decade, with vague references to user reports:
commit 8ab49e72af8465d4527de2ec37b22cd44f7a1169
Date: Wed Aug 19 13:55:34 2009 +0000
Disallow erase/write for known bad chips so people won't try without a clear understanding
Still, this logic does not belong in the high-level library logic, used
by all programmers and all chips. If there is a timing issue, it should
either be encoded in the appropriate programmer or flashchip timing.
However, we don't really know what chips were in use, as the above
commit doesn't have any links to reports. So in a feeble attempt at
avoiding breaking users here, we also surmise that...
* SPI chips weren't all that common in 2009;
* I'm mostly motivated by flashrom performance on Chromebooks, were SPI
chips (and linux_mtd / BUS_PROG) are the rule; and
* SPI chips have precise timing requirements and an appropriate BUSY
status. So we guess that this "calm down" magic delay wouldn't be
necessary there.
Thus, we allow this magic delay only on non-SPI (and non-BUG_PROG, used
by linux_mtd for one) buses as a compromise.
Now, this change has some (hopefully [1] tiny) chance of regression, so
we have the following considerations:
1. emergency_help_message() already provides documentation on how to
contact support, in case we need to handle any user-reported
regressions.
2. If there is any regression here, it's only in the --verify code; so
we can always provide workarounds for testing this, to determine
whether this change may have been at fault. For example, something
like:
flashrom --write /my/new/image.bin --noverify
sleep 1
flashrom --read /tmp/bar.bin
cmp /my/new/image.bin /tmp/bar.bin
If such problems occur, we can collect system/programmer/chip info to
try to encode a more targeted delay into the appropriate
chip/programmer implementation, and avoid penalizing the entire
project like this.
3. We already have (embedded in erase_write()) erase verification that
performs no such delay. So depending on the type of timing error that
this delay was attempting to cover, we may have some proof that this
delay is no longer necessary (or at least, that whatever systems were
needing this delay in the first place are no longer caring about
flashrom).
4. We've retained the delay for buses that were likely common in 2009
(per the above "feeble attempt").
NB: I avoid using the BUS_NONSPI macro, because I want to exclude any
future buses from this workaround, even in the event that the BUS_NONSPI
category grows in the future.
[1] Famous last words.

The test's correctness has been checked by testing with minimum sleep
time left at its default and set to a non-default value smaller than 100
microseconds (both pass without sleeping, verified with strace) and with
the minimum sleep time set to 0 (causing the test to be skipped). The

As proposed on the mailing list ("RFC: remove the calibrated delay
loop" [1]), this removes the calibrated delay loop and uses OS-based
timing functions for all delays because the calibrated delay loop can
delay for shorter times than intended.
When sleeping this now uses nanosleep() unconditionally, since usleep
was only used on DOS (where DJGPP lacks nanosleep). When busy-looping,
it uses clock_gettime() with CLOCK_MONOTONIC or CLOCK_REALTIME depending
on availability, and gettimeofday() otherwise.
The calibrated delay loop is retained for DOS only, because timer
resolution on DJGPP is only about 50 milliseconds. Since typical delays
in flashrom are around 10 microseconds, using OS timing there would
regress performance by around 500x. The old implementation is reused
with some branches removed based on the knowledge that timer resolution
will not be better than about 50 milliseconds.
Tested by reading and writing flash on several Intel and AMD systems:
* Lenovo P920 (Intel C620, read/verify only)
* "nissa" chromebook (Intel Alder Lake-N)
* "zork" chromebook (AMD Zen+)

`test_build.sh` is used by Jenkins, therefore it should build
everything. Docker container for Jenkins is expected to have all
the dependencies installed, and if some of them are missing, script
should fail.
Recently we had a situation when docker image was missing sphinx
and flashrom Jenkins was silently skipping building man-pages and
documentation. This patch prevents this happening again, because
building man pages and docs will be enforced.

This commit adds two new commands to the serprog protocol which allow
more fine grained control over the SPI bus. This enables more
applications over serprog like e.g. flashing AVR microcontrollers.
This can be tried with my forks of pico-serprog:
https://github.com/funkeleinhorn/pico-serprog/tree/spimode
and avrdude:
https://github.com/funkeleinhorn/avrgirl/tree/serprog-programmer
I announced this change in flashrom and flashprog IRC channels and got
overall positive feedback in the flashprog channel. The same changes
will be sent to flashprog to prevent diverging specs.
