* string: Allow arch override of strndup() alsoSimon Glass2020-02-051-1/+1
| | | | | | | At present architectures can override strdup() but not strndup(). Use the same option for both. Signed-off-by: Simon Glass <sjg@chromium.org>

* string: Include the config headerSimon Glass2018-11-201-0/+1
| | | | | | | At present the config header is not included in this file, but it does use a CONFIG option. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* string: Add strcspn()Simon Glass2017-06-011-0/+24
| | | | | | | Add an implementation of strcspn() which returns the number of initial characters that do not match any in a rejection list. Signed-off-by: Simon Glass <sjg@chromium.org>
* string: Add strchrnul()Simon Glass2017-06-011-0/+8
| | | | | | | This functions works like strchr() but returns the end of the string if the character is not found. Add an implementation of this. Signed-off-by: Simon Glass <sjg@chromium.org>
* string: Use memcpy() within memmove() when we canSimon Glass2017-05-091-9/+2
| | | | | | | | | | | A common use of memmove() can be handled by memcpy(). Also memcpy() includes an optimisation for large sizes: it copies a word at a time. So we can get a speed-up by calling memcpy() to handle our move in this case. Update memmove() to call memcpy() if the destination is before the source.

* string: Provide a slimmed-down memset()Simon Glass2017-04-041-2/+4
| | | | | | | | | | | Most of the time the optimised memset() is what we want. For extreme situations such as TPL it may be too large. For example on the 'rock' board, using a simple loop saves a useful 48 bytes. With gcc 4.9 and the rodata bug, this patch is enough to reduce the TPL image below the limit.

* Remove unneeded remnants of bcopy().Robert P. J. Day2016-06-061-24/+0
| | | | | | | Since bcopy() is no longer used, delete all remaining references to it. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca>
* lib: string: move strlcpy() to a common placeMasahiro Yamada2014-12-111-0/+25
| | | | | | | | | Move strlcpy() definition from drivers/usb/gadget/ether.c to lib/string.c because it is a very useful function. Let's add the prototype to include/linux/string.h too. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>

* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-311-0/+59
| | | | | | | | | | | | | | | | | | | | | | This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

* Make linux kernel string funcs available to toolsJoe Hershberger2012-12-131-39/+0
| | | | | | | | | | isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* Add strcasecmp() and strncasecmp()Simon Glass2012-12-111-4/+12
| | | | | | | | | | | strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org>
* nand: Sanitize ONFI strings.Christian Hitz2012-01-261-0/+39
| | | | | | | | | | | [backport from linux commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe] This is part of the synchronization with the nand driver to the Linux 3.0 state.

* memcpy/memmove: Do not copy to same addressMatthias Weisser2011-07-261-0/+6
| | | | | | | | In some cases (e.g. bootm with a elf payload which is already at the right position) there is a in place copy of data to the same address. Catching this saves some ms while booting. Signed-off-by: Matthias Weisser <weisserm@arcor.de>
* Rename lib_generic/ to lib/Peter Tyser2010-04-131-0/+605
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
