2014-11-23kbuild: use SoC-specific CONFIG to descend into SoC directoryMasahiro Yamada
Use "obj-$(CONFIG_FOO) += foo/" where it is possible. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-11-23kbuild: Descend into SOC directory from CPU directoryMasahiro Yamada
Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-03-28kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada
U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

2013-07-25nds32: Enable FPU if the version of CPU supportedken kuo
Some version of Andes core support FPU coprocessor, if this is the case, and toolchain support FPU instruction set, we should enable it at low level initialization time. Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>

2013-07-24nds32: ag101/ag102: Fix setting lastdec and now valuesAxel Lin
The timer3 counter unit for lastdesc and now values are inconsistent in current code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is second. However, CONFIG_SYS_HZ is defined as 1000 in board config file. This means the accuracy of "lastdec" and "now" should be in millisecond, thus fix the equation to set lastdec and now variables accordingly. Signed-off-by: Axel Lin <axel.lin@ingics.com>
2013-07-24nds32: Enable two banks of SDRAM on Andes boardken kuo
The original adp-ag101/adp-ag101p initialize only one bank(64MB) by default at boot time, but it is not enough for some application, so increasing to two banks(128M). Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>
2013-03-18Merge branch 'master' of git://git.denx.de/u-boot-armTom Rini
Albert's rework of the linker scripts conflicted with Simon's making everyone use __bss_end. We also had a minor conflict over README.scrapyard being added to in mainline and enhanced in u-boot-arm/master with proper formatting.

2013-03-15Replace __bss_end__ with __bss_endSimon Glass
Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-12Refactor linker-generated arraysAlbert ARIBAUD
Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

2012-10-22common: Discard the __u_boot_cmd sectionMarek Vasut
The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .
