* bitops: Add fls_long and __ffs64Fabio Estevam2015-11-05-0/+27
| | | | | | | Add fls_long and __ffs64 support to align with the kernel bitops implementation. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* linux/bitops.h: GENMASK copy from linuxJagan Teki2015-10-21-0/+11
| | | | | | | | | | | | GENMASK is used to create a contiguous bitmask([hi:lo]). This patch is a copy from Linux, with below commit details "bitops: Fix shift overflow in GENMASK macros" (sha1: 00b4d9a14125f1e51874def2b9de6092e007412d) Cc: Tom Rini <trini@konsulko.com> Cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Jagan Teki <jteki@openedev.com>
* linux/bitops: Move BIT definitions at topJagan Teki2015-10-21-4/+3
| | | | | | | | | Since it's a copy from Linux, this patch moved all BIT definitions to top so-that it looks same as Linux file. Cc: Tom Rini <trini@konsulko.com> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Signed-off-by: Jagan Teki <jteki@openedev.com>
* bitops: introduce BIT() definitionHeiko Schocher2015-09-11-0/+2
| | | | | | | | | | | introduce BIT() definition, used in at91_udc gadget driver. Signed-off-by: Heiko Schocher <hs@denx.de> [remove all other occurrences of BIT(x) definition] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com> Acked-by: Stefan Roese <sr@denx.de> Acked-by: Anatolij Gustschin <agust@denx.de>
* Correct ffs/fls regression for PowerPC etcSimon Kagstrom2009-09-17-4/+4
| | | | | | | | | | | | | | | Commits 02f99901ed1c9d828e3ea117f94ce2264bf8389e 52d61227b66d4099b39c8309ab37cb67ee09a405 introduced a regression where platform-specific ffs/fls implementations were defined away. This patch corrects that by using PLATFORM_xxx instead of the name itself.

* Define ffs/fls for all architecturesSimon Kagstrom2009-09-15-0/+45
| | | | | | | | UBIFS requires fls(), which is not defined for arm (and some other architectures) and this patch adds it. The implementation is taken from Linux and is generic. ffs() is also defined for those that miss it. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
* Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom2009-09-15-0/+38
| | | | | | | | | __set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
* * Code cleanup:wdenk2003-06-27-12/+12
| | | | | | | | | - remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
