2015-01-24x86: Implement a cache for Memory Reference Code parametersSimon Glass
The memory reference code takes a very long time to 'train' its SDRAM interface, around half a second. To avoid this delay on every boot we can store the parameters from the last training sessions to speed up the next. Add an implementation of this, storing the training data in CMOS RAM and SPI flash.

2015-01-23ls102xa: fdt: Disable QSPI and DSPI in NOR/NAND/SD bootAlison Wang
As QSPI/DSPI and IFC are pin multiplexed, QSPI and DSPI are only enabled in QSPI boot, and disabled in other boot modes. IFC is enabled in NOR/NAND/SD boot, and disabled in QSPI boot. This patch will add fdt support for the above rules. Signed-off-by: Alison Wang <alison.wang@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

CAAM is connected to CCI-400 S0 slave interface. Disable snooping for S0 will cause CAAM self test failure. This patch is to enable snooping for S0 slave interface. These CCI-400 operations are moved to board_early_init_f() to be initialized earlier. For S4 slave interface, issuing of snoop requests and DVM message requests are enabled.

2015-01-23ARM: HYP/non-sec: Make variable gic_dist_addr as a local onetang yuantian
Defining variable gic_dist_addr as a globe one prevents some functions, which use it, from being used before relocation which is the case in the deep sleep resume process on Freescale SoC platforms. Besides, we can always get the GIC base address by calling get_gicd_base_address() without referring gic_dist_addr.

2015-01-23arm: ls102xa: Add dummy gpio.h to enable CONFIG_OF_CONTROLRuchika Gupta
If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled. It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. As a result, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not support GPIO. The right fix would be to split the lib/fdtdec.c to remove dependency on GPIO.This commit adds a dummy <asm/arch/gpio.h> to support OF_CONTROL for LS102x platform. This dummy header will be removed after FDT-GPIO stuff is fixed correctly. Signed-off-by: Ruchika Gupta <ruchika.gupta@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

2015-01-23x86: Test mtrr support flag before accessing mtrr msrBin Meng
On some x86 processors (like Intel Quark) the MTRR registers are not supported. This is reflected by the CPUID (EAX 01H) result EDX[12]. Accessing the MTRR registers on such processors will cause #GP so we must test the support flag before accessing MTRR MSRs.

2015-01-23ARM: UniPhier: remove __packed that causes a problem on GCC 4.9Masahiro Yamada
The DDR PHY training function, ddrphy_prepare_training() would not work if compiled with GCC 4.9. The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h) is specified with __packed because it represents a hardware register mapping, but it turned out to cause a problem on GCC 4.9. If -mno-unaligned-access is specified (yes, it is in arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the __attribute__((packed)) and generates extra instructions to perform the memory access in a way that does not cause unaligned access. (Actually it is not need here because the register base, the first argument of the ddrphy_prepare_training(), is always given with a 4-byte aligned address.) Anyway, as a result, readl() / writel() is divided into byte-wise accesses. The problem is that this hardware only accepts 4-byte register access. Byte-wise accesses lead to unexpected behavior. There are some options to avoid this problem. [1] Remove -mno-unaligned-access [2] Add __aligned(4) along with __packed to struct ddrphy [3] Remove __packed from struct ddrphy [1] solves the problem for ARMv7, but it does not for pre-ARMv6 and ARMv6-M architectures where -mno-unaligned-access is default. So, [1] does not seem reasonable in terms of code portability. Both [2] and [3] work well, but [2] seems too much. All the members of struct ddrphy have the u32 type. No padding would be inserted even if __packed is dropped. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Reviewed-by: Tom Rini <trini@ti.com>

2015-01-22sunxi: video: Use frontend for dma on sun4i to fix memory bandwidth problemsHans de Goede
Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. On sun4i use the display frontend engine to do the dma from memory, as the frontend does have deep enough fifo-s. As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

2015-01-22sunxi: Stop differentiating between 512M and 1G variants of the same boardHans de Goede
While working on adding more boards I noticed that we lack a config for the 512M cubieboard, and that some of the new boards which I want to add also have 512M and 1G variants, rather then adding 2 defconfig's for all of these, lets switch the exising boards which have both a 512M and 1024M variant over to the sun4i dram autoconfig code. This also drops the foo_RAMSIZE_defconfig variants of boards where we currently have 2 separate configs already. Note: 1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with a value other then its default for now, but we need this to be configurable to support some new boards with auto dram config. 2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match the defaults, this is done to make it more clear what values are used for a certain board. This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G variants, the dram autoconfig code has also been tested on a 512M mk802 (a defconfig for the mk802 is added in a later patch).
