rockchip: rk3288: correct sdram setting

2016-03-10T15:32:01+00:00

The DMC driver in v3.14 kernel[0] get the ddr setting from PMU_SYS_REG2,
and it expects uboot to store the value using a same protocol. But now
the ddr setting value is different with DMC, so if you enable the DMC,
system would crash in kernel. Correct the sdram setting here, according
to the requirements of kernel.

rockchip: make configure_emmc() empty for Firefly-RK3288

2016-03-10T15:32:01+00:00

on v2016.03-rc3, size of SPL image compiled by gcc 5.3.0 is too large for
Firefly-RK3288. (it's fine for Rock2)

$ gcc --version

Warning: SPL image is too large (size 0x80d0) and will not boot

to reduce size of SPL image, this patch makes configure_emmc() empty for
Firefly-RK3288 as same as Rock2.

rockchip: rk3036: change ddr frequency to 400M

2016-03-10T15:32:01+00:00

emac may use dpll as clock parent, and it request the clock frequency
multiples of 50, so change ddr frequency to 400M.

omap3: Use raw SPL by default for mmc1

2016-03-08T20:01:46+00:00

Now that we fall back to the FS code path when we don't find u-boot
at the raw sector offset, there is no good reason to not default to
raw boot.

With this patch, I can successfully boot u-boot from a raw sector
offset on beagle-xm.

ARM: uniphier: allow debug_ll_init() to do nothing for unknown SoCs

This function should just return for unknown SoCs rather than writing
unexpected values to registers.

colibri-vf: Disable pull-up configuration in GPIO pin mux

2016-03-02T13:47:16+00:00

During very early boot-ROM execution the pinmux
configuration isi in Hi-Z state. If pull-up is enabled
on GPIO pad's there will be a short period of toggle
from high to low on the IO when GPIO is set low during
boot. To avoid this glitch, disable pull-up configuration
in GPIO pinmux.

ARM: uniphier: fix warnings reported by aarch64 compiler

2016-02-29T15:33:29+00:00

The UniPhier SoC family has not supported ARMv8 yet, but these would
cause warnings if they were compiled with a 64bit compiler.  Before
adding the ARMv8 support really, fix them now.

Because UniPhier SoCs do not support Large Physical Address Extension,
casting "phys_addr_t" into "unsigned long" would carry the address
as is.
