2015-04-07am33xx/ddr.c: Fix regression on DDR2 platformsTom Rini
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. Tested on Beaglebone White, Beaglebone Black and AM335x GP EVM Reported-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Tom Rini <trini@konsulko.com>

2015-04-06Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panelsAjay Kumar
The existing setting for rpll_sdiv generates 70.5Mhz RPLL video clock to drive 1366x768 panel on peach_pit. 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.

2015-04-03arc: add support for SLC (System Level Cache, AKA L2-cache)Alexey Brodkin
ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache). This change adds functions required for controlling SLC: * slc_enable/disable * slc_flush/invalidate For now we just disable SLC to escape DMA coherency issues until either: * SLC flush/invalidate is supported in DMA APIin U-Boot * hardware DMA coherency is implemented (that might be board specific so probably we'll need to have a separate Kconfig option for controlling SLC explicitly) Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2015-04-03arc: minor fixes in KconfigAlexey Brodkin
[1] Fix misspeling in ARC_CACHE_LINE_SHIFT dependency, now cache-line lenth selection is correctly enabled if either I$ or D$ are enabled. [2] Add dummy entry to target list to make sure target type is always mentioned in defconfig. Otherwise defconfig for the first target in the list will not have target name and later on with addition of the new target on top of the list in Kconfig will lead to corrupted configuration expanded from defconfig.

2015-04-03arc: get rid of CONFIG_SYS_GENERIC_GLOBAL_DATAAlexey Brodkin
As discussed on mailing list we're drifting away from CONFIG_SYS_GENERIC_GLOBAL_DATA in favour to use of board_init_f_mem() for global data. So do this for ARC architecture. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-04-03arc: clean-up init procedureAlexey Brodkin
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>
2015-04-03arc: move low-level interrupt and exception handlers in a separate fileAlexey Brodkin
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. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-04-03arc: merge common start-up code between ARC and ARCv2Alexey Brodkin
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>
2015-04-03arc: cache - build invalidate_icache_all() and invalidate_dcache_all()Alexey Brodkin
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.

The android kernel has a work around for this in the form of temporary disabling the phy's squelch detection on reset deassert, this commit adds the same workaround to the u-boot sunxi musb code, thereby fixing various usb lo speed devices not working.
