Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/38671 ) Change subject: programmer: Introduce programmer alias mechanism ...................................................................... programmer: Introduce programmer alias mechanism Originally introduced in the downstream commit ba0827acee4da6740133345f43aae386923bbaad . This was originally authored by David Hendricks so that the various flash peripheral in ChromeOS devices can be flashed. For example, flashrom -p ec -r ec.bin flashrom -p host -r host.bin Note that this requires, `CONFIG_DEFAULT_PROGRAMMER=PROGRAMMER_INTERNAL make` to be defined as build-time.

Change in flashrom[master]: udelay.c: Enable providing delay calibration value through CLI
by Hrvoje Čavrak (Code Review) 17 Aug '20

17 Aug '20

Hrvoje Čavrak has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/39841 ) Change subject: udelay.c: Enable providing delay calibration value through CLI ...................................................................... udelay.c: Enable providing delay calibration value through CLI This commit implements --delay option to retrieve and provide the calibration loop delay through the command line. The delay calibration procedure can take up to few seconds, which adds up when executed a number of times consecutively. Therefore, this provides a means to execute it only once, and then re-use the calibrated value on subsequent runs. Also, it implements a sanity check, expecting the value to land within 10% of the theoretical delay expectance, otherwise it ignores the provided value and runs the calibration procedure instead. modified: cli_classic.c modified: flashrom.8.tmpl modified: programmer.h modified: udelay.c Change-Id: Iea2a7f62300663bc0a32ed4abced57c8c55c90c8 Signed-off-by: Hrvoje Cavrak <hrvoje(a)hrvoje.org> --- M cli_classic.c M flashrom.8.tmpl M programmer.h M udelay.c 4 files changed, 51 insertions(+), 3 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/41/39841/1 diff --git a/cli_classic.c b/cli_classic.c index 73cc417..f0842d4 100644 --- a/cli_classic.c +++ b/cli_classic.c @@ -63,6 +63,8 @@ " -o | --output <logfile> log output to <logfile>\n" " --flash-contents <ref-file> assume flash contents to be <ref-file>\n" " -L | --list-supported print supported devices\n" + " -d | --loop-delay <value> set loop delay calibration manually\n" + " --loop-delay get show loop delay calibration\n" #if CONFIG_PRINT_WIKI == 1 " -z | --list-supported-wiki print supported devices in wiki syntax\n" #endif @@ -118,6 +120,7 @@ int flash_name = 0, flash_size = 0; int read_it = 0, write_it = 0, erase_it = 0, verify_it = 0; int dont_verify_it = 0, dont_verify_all = 0, list_supported = 0, operation_specified = 0; + unsigned long provided_delay = 0; struct flashrom_layout *layout = NULL; enum programmer prog = PROGRAMMER_INVALID; enum { @@ -130,7 +133,7 @@ }; int ret = 0; - static const char optstring[] = "r:Rw:v:nNVEfc:l:i:p:Lzho:"; + static const char optstring[] = "r:Rw:v:nNVEfc:l:i:p:Lzho:d:"; static const struct option long_options[] = { {"read", 1, NULL, 'r'}, {"write", 1, NULL, 'w'}, @@ -156,6 +159,7 @@ {"help", 0, NULL, 'h'}, {"version", 0, NULL, 'R'}, {"output", 1, NULL, 'o'}, + {"delay", 1, NULL, 'd'}, {NULL, 0, NULL, 0}, }; @@ -362,6 +366,14 @@ } #endif /* STANDALONE */ break; + case 'd': + provided_delay = strtoul(strdup(optarg), NULL, 0); + if (!provided_delay) { + /* Make it easy for scripts to parse this by omitting anything else */ + msg_pinfo("%lu\n", get_calibration_value()); + exit(0); + } + break; default: cli_classic_abort_usage(NULL); break; @@ -454,7 +466,10 @@ } /* FIXME: Delay calibration should happen in programmer code. */ - myusec_calibrate_delay(); + if (provided_delay) + set_external_calibration(provided_delay); + else + myusec_calibrate_delay(); if (programmer_init(prog, pparam)) { msg_perr("Error: Programmer initialization failed.\n"); diff --git a/flashrom.8.tmpl b/flashrom.8.tmpl index fde98c0..c14f2de 100644 --- a/flashrom.8.tmpl +++ b/flashrom.8.tmpl @@ -50,7 +50,7 @@ [\fB\-E\fR|\fB\-r\fR <file>|\fB\-w\fR <file>|\fB\-v\fR <file>] [(\fB\-l\fR <file>|\fB\-\-ifd|\fB \-\-fmap\fR|\fB\-\-fmap-file\fR <file>) [\fB\-i\fR <image>]] [\fB\-n\fR] [\fB\-N\fR] [\fB\-f\fR])] - [\fB\-V\fR[\fBV\fR[\fBV\fR]]] [\fB-o\fR <logfile>] + [\fB\-V\fR[\fBV\fR[\fBV\fR]]] [\fB-o\fR <logfile>] [\fB-d\fR get | <value>] .SH DESCRIPTION .B flashrom is a utility for detecting, reading, writing, verifying and erasing flash @@ -364,6 +364,18 @@ .TP .B "\-R, \-\-version" Show version information and exit. +.TP +.B "\-d, \-\-loop\-delay" +Retrieve the loop calibration delay value or provide one externally.

Change in flashrom[master]: sb600spi -> fchspi: Rename AMD SPI programmer
by Edward O'Callaghan (Code Review) 24 Jun '20

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/36434 ) Change subject: sb600spi -> fchspi: Rename AMD SPI programmer ...................................................................... sb600spi -> fchspi: Rename AMD SPI programmer The AMD FCH controller has two main SPI ip core variants, the so-called 'sb600' variant and the newer 'spi100' variant. The sb600spi.c driver supports both variants and so its name isn't very general. Here we rename it to be more general.

Change in flashrom[master]: sb600spi.c: Improve IMC runtime detection in handle_imc()
by Edward O'Callaghan (Code Review) 24 Jun '20

24 Jun '20

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/36424 ) Change subject: sb600spi.c: Improve IMC runtime detection in handle_imc() ...................................................................... sb600spi.c: Improve IMC runtime detection in handle_imc() The IMC detection in sb600spi is very rudimentary and incomplete. This expands it so that it can actually detect not only whether an IMC is in the system, but whether it's active or not. This is based off ChromiumOS's fork of flashrom where the solution looks to be originally authored by Martin Roth in b/62141938.

Change in flashrom[master]: [WIP] Add .clang-format to help with patch formatting

Hello Vadim Bendebury, I'd like you to do a code review. Please visit https://review.coreboot.org/c/flashrom/+/38673 to review the following change. Change subject: [WIP] Add .clang-format to help with patch formatting ...................................................................... [WIP] Add .clang-format to help with patch formatting This is based on CB:38208 by Vadim, but with a few added changes. Here is the original commit message. This is a copy from the coreboot tree, could be tweaked to better match the flashrom tree if there are any differences. Once this file is in place a script could be deployed which would format only new/changed lines in git patches.
