Move remaining NOR flash implemenation into flash/nor/core.c
Removes flash.c from the build, leaving only its header to split.
|
|
Encapsulates access to the flash_drivers array, providing a base
of operations for future dynamic driver module loading features.
|
|
Splits the exec mode commands out of flash.c into the flash/nor/ files.
The routines used by these high-level commands are moved into nor/core.c,
with their internal declarations placed in nor/imp.h.
Fixes distribution of <flash/nor/core.h> header.
|
|
Moves the top-level 'flash' command handlers into flash/nor/tcl.c,
with flash/nor/imp.h providing an internal implementation header
to share non-public API components.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "image.h"
the following form should be used.
#include <target/image.h>
The exception is from .c files in the same directory.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "time_support.h"
the following form should be used.
#include <helper/time_support.h>
The exception is from .c files in the same directory.

Split flash initialiation into 'flash init', called from 'init'.
|
|
Command upgrading introduced two off-by-one bugs in the flash commands.
This patch fixes the 'flash {protect,erase_sector}' commands to check
that they have been passed the correct number of arguments.
Ammended during commit to fix help text for 'erase_address' too.
|
|
Adding jim_handler field to command_registration allows removing the
register_jim helper. All command registrations now go through the
register_command{,s}() functions.
|
|
Replace flash_driver callback with pointer to command_registration.
Eliminates all related routines and allows drivers to omit commands.
|
|
Eliminates 'flash_cmd' global variable.
|
|
Replaces direct calls to register_command() with a macro, to allow
its parameters to be changed and callers updated in phases.
|
|
Allocate working memory rather than using stack.

|
Requires users to name their flash banks, allowing them to be used
instead of bank numbers in script commands.
|
|
Move variables to point of first use, reducing their scope.
Add driver_name temporary to help arguments be changed later.
Eliminates the useless 'found' variable, changing the code to terminate
the loop immediate and return its success.
|
|
After adding support for referencing banks by name, renames
the COMMAND_HELPERs appropriately:
flash_command_get_bank_by_num -> flash_command_get_bank
nand_command_get_device_by_num -> flash_command_get_device
|
|
Add get_flash_bank_by_name (and get_nand_device_by_name) helpers
to retrieves struct flash_bank * (struct nand_device *) given a
driver name and an (optional) driver-specific bank index.
These are used to extend flash_command_get_bank_by_num (and
nand_command_get_device_by_num) to allow all flash (nand) commands to
reference defined banks by name, not just by number.
To avoid some code duplication, add the flash/common.[ch] files to hold
functionality common to both types driver. The first two methods are
helpers for the above routines to find a bank specified by a "name" or
"name.index" string. get_flash_name_index() finds the '.index' portion,
while flash_driver_name_matches() performs the string portion matching.

Updates all command parsing of "on" and "off" arguments.
|
|
Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
|
|
This patch converts all instances of 'args' in COMMAND_HANDLER routines
to use CMD_ARGV macro.
|
|
This patch converts all instances of 'argc' in COMMAND_HANDLER routines
to use CMD_ARGC.

Use size_t instead of uint32_t when specifying file sizes. Update all
consumers up through the layers to use size_t when required. These
changes should be safe, but the higher-levels will need to be updated
further to receive the intended benefits (i.e. large file support).
Add error checking for fileio_read and file_write. Previously, all
errors were being silently ignored, so this change might cause some
problems for some people in some cases. However, it gives us the chance
to handle any errors that do occur at higher-levels, rather than burying
our heads in the sand.
|
|
Add const keyword to file url and cast to free().
Make size an ssize_t and chase all format strings that use it.
|
|
Use COMMAND_HELPER macro to declare flash_command_get_bank_by_num.
This is required for COMMAND_PARSE_NUMBER macro.
|
|
Remove misleading typedef and redundant suffix from struct command.
|
|
Remove misleading typedef and redundant suffix from struct command_context.
|
|
Remove misleading typedef and redundant suffix from struct flash_bank.
|
|
Remove misleading typedef and redundant suffix from struct target.
|
|
Remove misleading typedef and redundant suffix from struct image.
Also removes the typedef from enum image_type, as it is used in
image.h only.
|
|
Remove misleading typedef and redundant suffix from struct flash_driver.
|
|
Remove useless structure typedef.
|
|
By introducing the CMD_NAME macro, this parameter may be integrated
as args[-1] in command.[ch], without touching any other call sites.
|
|
By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.
|
|
|
|
Add 'const' keyword to 'char *' parameters to allow command handlers to
pass constant string arguments. These changes allow the 'args' command
handler to be changed to 'const' in a subsequent patch.
|
|
Remove useless forward declarations.
Moves command registration to end of file.
Moves flash structure definition to end of file.

This patch changes the duration_* API in several ways. First, it
updates the API to use better names. Second, string formatting has
been removed from the API (with its associated malloc). Finally, a
new function added to convert the time into seconds, which can be
used (or formatted) by the caller. This eliminates hidden calls to
malloc that require associated calls to free().
This patch also removes the useless extern keyword from prototypes,
and it eliminates the duration_t typedef (use 'struct duration').
These API also allows proper error checking, as it is possible for
gettimeofday to fail in certain circumstances.
The consumers have all been chased to use this new API as well, as
there were relatively few cases doing this type of measurement.
In most cases, the code performs additional checks for errors, but
the calling code looks much cleaner in every case.

Removes redundant tests and reverses backwards logic to reduce the
indentation level in flash.c.
|
|
|
|
This eliminates redundant code for parsing and retreiving the bank
specified from a script command argument. This patch was written to
replace existing functionality; however, the parsing logic can be
updated later to allow flash commands to accept bank names as well as
their numbers.

print the real number of bytes written
