| * | | ARM: move -march=* and -mtune= options to arch/arm/MakefileMasahiro Yamada2015-03-27-69/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My main motivations for this commit are: [1] Follow the arch/arm/Makefile style of Linux Kernel [2] Maintain compiler options systematically Currently, we give -march=* and -mtune=* options inconsistently: Only some of the CPUs pass -march=* and -mtune=* options. By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.

* | | | common, ubi: use positive return values for ubi checkStefan Agner2015-04-10-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ubi check command is expected to not fail and just check whether a volume exist or not. Currently, when a volume does not exist, the command fails which leads to an error: "exit not allowed from main input shell." Use 1 to indicate that a volume does not exist. This allows to use ubi check in an if statement, e.g. if ubi check rootfs; then; echo "exists"; else; echo "not there"; fi

That commit forcibly turned on CONFIG_SYS_MALLOC_F. I have not figured out the root cause, but anyway it looks like CONFIG_SYS_MALLOC_F gave a bad impact on the Zynq MMC boot. We are planning to have the v2015.04 release in a few days. I know this is a defensive fixup, but what I can do now is to add # CONFIG_SYS_MALLOC_F is not set to every Zynq defconfig file to get back the original behavior.

* | | MAKEALL: fix get_target_arch() to adjust to '-' in Status fieldMasahiro Yamada2015-04-07-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the Kconfig conversion, boards.cfg scanned by MAKEALL is generated by tools/genboardscfg.py. Every board is supposed to have its own MAINTAINERS that contains maintainer and status information, but, in fact, MAINTAINERS is missing from some boards. For such boards, the first field, Status, is filled with '-'. It causes a problem for "set" command, which ignores '-' in its arguments. Consequently, get_target_arch() returns a wrong field and MAKEALL fails to get a correct toolchain. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

It causes build error if both files have the same time-stamps. It is actually possible because EXT* file systems have a 1s time-stamp resolution. The config.mk should be included when include/config/auto.conf is *not older* than the .config file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in fc46bae a "clean up" was introduced that intended to reconcile some of the AM335x codepaths based on how AM43xx operates. Unfortunately this introduced a regression on the DDR2 platforms. This was un-noticed on DDR3 (everything except for Beaglebone White) as we had already populated sdram_config correctly in sequence. This change brings us back to the older behavior and is fine on all platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In stead of user_buffer_size, transfer_size should be used to pass to ahci_device_data_io(). transfer_size is the length that we want the low level function to transfer each time. If we use user_buffer_size which is the totally data length as parameter, low level function will actually create many SGs to transfer as many data as possible each time. That will produce many redundant data transfer. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* | | env_sf: Fix recovery defaultMario Schuknecht2015-04-07-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The u-boot environment is redundantly stored in a NOR flash on our boards. Redundant means that there are two places to store the environment. But only one of the two is active. I discovered that on one board the u-boot (env_sf) uses the environment from the second place and the Kernel (fw_printenv) uses the environment from the first place. To decide which is the active environment there is a byte inside the environment. 1 means active and 0 means obsolete. But on that board both environments had have a 1. This can happen if a power loss or reset occurs during writing the environment. In this situation the u-boot (env_sf) implementation uses the second environment as default. But the Kernel (fw_printenv) implementation uses the first environment as default. This commit corrects the default in the u-boot env_sf implementation when a problem was detected. Now the recovery default is the same like in all other environment implementations. E.g. fw_printenv and env_flash. This ensures that u-boot and Kernel use the same environment.

This clock rate is not sufficient to drive 1920x1080 panel on peach-pi. So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock which can drive peach-pi LCD. This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD divider at IP level will get set to 1(the required divider setting will be calculated and set by exynos_fimd_set_clock()) and hence peach-pit LCD still works fine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intention behind this work was elimination of as much assembly-written code as it is possible. In case of ARC we already have relocation fix-up implemented in C so why don't we use C for U-Boot copying, .bss zeroing etc. It turned out x86 uses pretty similar approach so we re-used parts of code in "board_f.c" initially implemented for x86. Now assembly usage during init is limited to stack- and frame-pointer setup before and after relocation. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Simon Glass <sjg@chromium.org>
| * | | arc: move low-level interrupt and exception handlers in a separate fileAlexey Brodkin2015-04-03-144/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This separation makes maintenance of code easier because those low-level interrupt- or exception handling routines are pretty static and usually require not much care while start-up code is a subject of modifications and enhancements.

| * | | arc: merge common start-up code between ARC and ARCv2Alexey Brodkin2015-04-03-294/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though ARCompact and ARCv2 are not binary compatible most of assembly instructions are used in both. With this change we'll get rid of duplicate code. Still IVTs are implemented differently so we're keeping them in separate files. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
| * | | arc: cache - build invalidate_icache_all() and invalidate_dcache_all()Alexey Brodkin2015-04-03-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | always Make both invalidate_icache_all() and invalidate_dcache_all() available even if U-Boot is configured with CONFIG_SYS_DCACHE_OFF and/or CONFIG_SYS_ICACHE_OFF. This is useful because configuration of U-Boot may not match actual hardware features. Real board may have cache(s) but for some reason we may want to run U-Boot with cache(s) disabled (for example if some peripherals work improperly with existing drivers if data cache is enabled). So board may start with cache(s) enabled (that's the case for ARC cores with built-in caches) but early in U-Boot we disable cache(s) and make sure all contents of data cache gets flushed in RAM.
