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.

2015-03-29sunxi: musb: Fix some lo speed devices not working with musb hostHans de Goede
The usb0 / otg phy on sunxi boards has a bug where it wrongly detects a high speed squelch on usb reset deassert when a lo speed device is plugged in. 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. Tested with a (before non working) usb keyboard and a usb 2.4 GHz wireless keyboard/mouse combo receiver.

2015-03-27ARM: move -march=* and -mtune= options to arch/arm/MakefileMasahiro Yamada
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.

2015-03-24ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot properMasahiro Yamada
The L2 cache is used as a temporary SRAM on SPL. Now the secondary CPUs store the necessary code for jumping to Linux on their L1 I-caches. So, the L2 cache can be disabled much earlier, at the very entry of U-Boot proper (lowlevel_init). This makes the boot sequence clearer. Also, as the L1 cache has been disabled by the start.S, enable_caches() does not need to do it again. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
