[U-Boot] arm kirkwood pending patches
by Luka Perkov 29 Nov '14

29 Nov '14

Hi, I have noticed that there are 3 pending kirkwood patches that I've sent a while back. It seems that there has been no action since then. Patches have been ACKed... Can we get some progress on these: http://patchwork.ozlabs.org/patch/366225/ http://patchwork.ozlabs.org/patch/366226/ http://patchwork.ozlabs.org/patch/366227/ Thanks. Regards, Luka

[U-Boot] [PATCH] arm: exynos: fix the div value for set_mmc_clk
by Jaehoon Chung 28 Nov '14

28 Nov '14

The most exynos used the "Ratio + 1" as div value. And value at register is "Ratio". So if want to set exact value, it needs to subtract one. Value at register ("Ratio") = div - 1 Signed-off-by: Jaehoon Chung <jh80.chung(a)samsung.com> --- arch/arm/cpu/armv7/exynos/clock.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/arm/cpu/armv7/exynos/clock.c b/arch/arm/cpu/armv7/exynos/clock.c index 4ecce44..6633ffe 100644 --- a/arch/arm/cpu/armv7/exynos/clock.c +++ b/arch/arm/cpu/armv7/exynos/clock.c @@ -1654,6 +1654,12 @@ unsigned long get_mmc_clk(int dev_index) void set_mmc_clk(int dev_index, unsigned int div) { + /* + * If want to set correct value, it needs to substract one from div. + */ + if (div > 0) + div -= 1; + if (cpu_is_exynos5()) { if (proid_is_exynos5420() || proid_is_exynos5800()) exynos5420_set_mmc_clk(dev_index, div); -- 1.9.1

[U-Boot] ARM: PSCI 0.1 vs 0.2
by Jan Kiszka 28 Nov '14

28 Nov '14

Hi Marc, what is the motivation to expose a PSCI 0.1 interface in U-boot, instead of 0.2? Support for preexisting users of 0.1? The kernel seems to be happy with both, and I'm now wondering if we should actually add the legacy version to Jailhouse as well (I hope we can avoid this). Still studying the logic: Is it possible to provide both interfaces, and would it make sense? Jan

[U-Boot] [PATCH] mtd/nand/vf610_nfc: Disable subpage writes
by Sanchayan Maity 28 Nov '14

28 Nov '14

This patch disables subpage writes for vf610_nfc nand driver. This is required, as without this fix, writing unaligned u-boot images with DFU results in a hang. Trying to write unalgined binary images also results in a hang, without disabling subpage writes. Patch has been tested on a Colibri VF61 module.

[U-Boot] [PATCH] fdt: remove fdtdec_get_alias_node() function
by Masahiro Yamada 28 Nov '14

[U-Boot] [PATCH v1] fdt: Allow non-FDT kernels to boot when CONFIG_OF_LIBFDT is defined
by Suriyan Ramasami 27 Nov '14

27 Nov '14

The boot commands - bootz/bootm mandate a third argument which is the address to the FDT blob. In cases where this argument is not specified, boot fails with a message indicating a missing FDT. This causes non-FDT kernels to fail to boot. This patch allows both FDT and non-FDT kernels to boot by making the third parameter to the bootm/bootz optional.

It would be nice to make x86 a first-class U-Boot citizen, meaning that it has a reasonable set of features as required by a reasonable set of modern boards. That means supporting a few more classes of chipsets. Then we get all the features that U-Boot has, hopefully without to much of the BIOS-era baggage that x86 often brings along (U-Boot is pretty simple to understand). I'm pretty happy that the current port fits well into the U-Boot philosophy. The binary blobs are certainly a problem, but we deal with them in other cases also - e.g. some ARM SoCs require a signed pre-boot image. Something to discuss I suppose. Regards, Simon
