[PATCH 2/6] layout: Add -i <region>[:<file>] support.
by Stefan Tauner 23 Sep '13

23 Sep '13

Add an optional sub-parameter to the -i parameter to allow building the image to be written from multiple files. This will also allow regions to be read from flash and written to separate image files in a later patch. Existing function read_buf_from_file() is refined and reused to read the file. based on chromiumos' d0ea9ed71e7f86bb8e8db2ca7c32a96de25343d8 Signed-off-by: David Hendricks <dhendrix(a)chromium.org> Signed-off-by: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> --- cli_classic.c | 9 ++++--- dummyflasher.c | 2 +- flash.h | 2 +- flashrom.c | 18 +++++++++----- layout.c | 78 ++++++++++++++++++++++++++++++++++++++++++++-------------- 5 files changed, 78 insertions(+), 31 deletions(-) diff --git a/cli_classic.c b/cli_classic.c index a0c2d64..ed6d6aa 100644 --- a/cli_classic.c +++ b/cli_classic.c @@ -40,8 +40,8 @@ static void cli_classic_usage(const char *name) #if CONFIG_PRINT_WIKI == 1 "-z|" #endif - "-p <programmername>[:<parameters>] [-c <chipname>]\n" - "[-E|(-r|-w|-v) <file>] [-l <layoutfile> [-i <imagename>]...] [-n] [-f]]\n" + "-p <programmername>[:<parameter>[,<parameter>]...] [-c <chipname>]\n" + "[-E|(-r|-w|-v) <imagefile>] [-l <layoutfile> [-i <region>[:<regionfile>]...] [-n] [-f]]\n" "[-V[V[V]]] [-o <logfile>]\n\n", name);

[PATCH 1/6] Introduce helpers.c and unquote_string().
by Stefan Tauner 23 Sep '13

23 Sep '13

The unquoting function is the first to be moved to the new file which will host various utility functions to be shared by multiple files but which do not fit elsewhere. unquote_string() extracts a possibly quoted phrase from a string by using a set of separator characters, which is useful to allow user input to be optionally quoted to support spaces within names such a region or file names.

[PATCH 0/6] layout patches 4.0
by Stefan Tauner 23 Sep '13

23 Sep '13

Implementation of unquote_string() combining ideas from CD and myself. Refined parser, new support for top-aligned address and flags. And the last patch is open for discussion... it tests readability and size of the --include files while parsing it and before actually reading them (which only happens after a full chip read). It is obviously useful for slow programmers because it can bail out early when there are obvious problems with the file, but it is still quite some overhead and it feels rather dumb to check this twice. Maybe we should already read them in early instead of just checking? The disadvantage is that we would need to allocate extra buffers for them. The late read writes directly to newcontents and hence does not need an extra buffer. Stefan Tauner (6): Introduce helpers.c and unquote_string(). layout: Add -i <region>[:<file>] support. layout: Better file parsing. layout: Add support for top-aligned addresses. layout: Add preliminary support for flags. [WIP] layout: Bailout early in process_include_args() if region file is inaccessible.

Author: stefanct Date: Mon Sep 23 17:32:25 2013 New Revision: 1752 URL: http://flashrom.org/trac/flashrom/changeset/1752 Log: layout: Verify layout entries before building a new image using them. This fixes a SEGFAULT if a layout entry is included that addresses memory outside the current chip's address range. flashrom will only abort if the offending region(s) is/are included else it will just warn. It will print warnings for regions with negative or zero-length address ranges too, but it will only abort if they are included with -i/--image to reduce the potential of regressions. This is different to the patch committed to the development branch in r1751. Also, abort for non-write operations if a layout file is given because there is no layout support for non-write operations yet, and some reports show that users expect it to work at least for -r/--read.

Author: stefanct Date: Mon Sep 23 16:21:06 2013 New Revision: 1751 URL: http://flashrom.org/trac/flashrom/changeset/1751 Log: layout: Verify layout entries before building a new image using them. This fixes a SEGFAULT if a layout entry is included that addresses memory outside the current chip's address range. flashrom will only abort if the offending region(s) is/are included else it will just warn. It will print warnings for regions with negative or zero-length address ranges and bail out after checking all of them. Also, abort for non-write operations if a layout file is given because there is no layout support for other operations yet.
