2020-02-05string: Allow arch override of strndup() alsoSimon Glass
At present architectures can override strdup() but not strndup(). Use the same option for both. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-11-20string: Include the config headerSimon Glass
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>
2017-06-01string: Add strcspn()Simon Glass
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>
2017-06-01string: Add strchrnul()Simon Glass
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>
2017-05-09string: Use memcpy() within memmove() when we canSimon Glass
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.

2017-04-04string: Provide a slimmed-down memset()Simon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Stuebner <heiko@sntech.de>
2016-06-06Remove unneeded remnants of bcopy().Robert P. J. Day
Since bcopy() is no longer used, delete all remaining references to it. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca>
2014-12-11lib: string: move strlcpy() to a common placeMasahiro Yamada
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>

2013-05-31mtd: resync with Linux-3.7.1Sergey Lapin
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.

2012-12-13Make linux kernel string funcs available to toolsJoe Hershberger
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>
2012-12-11Add strcasecmp() and strncasecmp()Simon Glass
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>
2012-01-26nand: Sanitize ONFI strings.Christian Hitz
[backport from linux commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe] This is part of the synchronization with the nand driver to the Linux 3.0 state. Signed-off-by: Christian Hitz <christian.hitz@aizo.com> Cc: Scott Wood <scottwood@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
2011-07-26memcpy/memmove: Do not copy to same addressMatthias Weisser
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>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
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>
