2015-02-24armv8/fsl-lsch3: Add support for second DDR clockYork Sun
FSL-LSCH3 platforms can have multiple DDR clocks. LS2085A has one clock for general DDR controlers, and another clock for DP-DDR. DDR driver needs to change to support multiple clocks. Signed-off-by: York Sun <yorksun@freescale.com>
2015-02-24driver/ddr/fsl: Add workaround for A008336York Sun

2015-02-24armv8/fsl-lsch3: Convert flushing L3 to assembly to avoid using stackYork Sun
Flushing L3 cache in CCN-504 requries d-cache to be disabled. Using assembly function to guarantee stack is not used before flushing is completed. Timeout is needed for simualtor on which CCN-504 is not implemented. Return value can be checked for timeout situation. Change bootm.c to disable dcache instead of simply flushing, required by flushing L3. Signed-off-by: York Sun <yorksun@freescale.com>

2015-02-24fsl-ch3/lowlevel: TZPC and TZASC programming to configure non-secure accessesBhupesh Sharma
This patch ensures that the TZPC (BP147) and TZASC-400 programming happens for LS2085A SoC only when the desired config flags are enabled and ensures that the TZPC programming is done to allow Non-secure (NS) + secure (S) transactions only for DCGF registers. The TZASC component is not present on LS2085A-Rev1, so the TZASC-400 config flag is turned OFF for now.

2015-02-21ARM: prepare for moving SoC sources into mach-*Masahiro Yamada
In U-boot, the directory structure, arch/$(ARCH)/cpu/$(CPU)/$(SOC)/ has been adopted except that $(CPU) is missing from some architectures and $(SOC) is missing from some CPUs. This structure did not fit very well in some cases. [1] AT91 AT91 SoC family have been developed across some ARM processor generations. Generally speaking, some IPs are often re-used in the same SoC family (same SoC vendor) even when the main processor is updated. As a result, a SoC-common directory is needed in the upper level. Currently, AT91 source files are placed as follows: arch/arm/cpu/arm920t/at91/* arch/arm/cpu/arm926ejs/at91/* arch/arm/cpu/armv7/at91/* arch/arm/cpu/at91-common/* Once directories are split, the motivation for refactorings across CPU directories is lost. Some files in arm920t/at91/ and arm926ejs/at91/ are so similar that they could be merged. [2] Tegra Tegra is a little bit special case where different CPUs are used for SPL and the main U-boot. To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC) structure, the source files must be placed across the CPUs, again SoC-common directory is necessary in the upper level. Moreover, there are several families in Tegra: Tegra20, Tegra30, Tegra114, Tegra124. Here again, the tegra-common directory is needed to contain commonly-used files. Tegra directories have been sprinkled in the directory structure. arch/arm/cpu/arm720t/tegra20 arch/arm/cpu/arm720t/tegra30 arch/arm/cpu/arm720t/tegra114 arch/arm/cpu/arm720t/tegra124 arch/arm/cpu/arm720t/tegra-common arch/arm/cpu/armv7/tegra20 arch/arm/cpu/armv7/tegra30 arch/arm/cpu/armv7/tegra114 arch/arm/cpu/armv7/tegra124 arch/arm/cpu/armv7/tegra-common arch/arm/cpu/tegra20-common arch/arm/cpu/tegra30-common arch/arm/cpu/tegra114-common arch/arm/cpu/tegra124-common arch/arm/cpu/tegra-common As you see, splitting SoC code by the CPU is not going well, especially for ARM. Why don't we collect SoC-specific files into a single place? A good example we can follow is Linux's arch/arm/mach-* structure. This item was discussed in the following thread: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/ Looks like I got some positive responses and we are almost ready to start this movement. This commit prepares arch/arm/Makefile for describing machdirs in it. After this commit, we can move SoC directory to arch/arm/mach-$(SOC) in simple steps although some cases such as AT91 and Tegra need more fixes. What we generally have to do is: [1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/* [2] Add machine entry into arch/arm/Makefile [3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile [4] Fix the Kconfig file path in arch/arm/Kconfig [5] Modify MAINTAINERS if necessary Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2015-02-16sunxi: Support the FEL boot mode in the regular u-boot buildSiarhei Siamashka
So that the CONFIG_SPL_FEL option is not needed anymore. And the regular SPL binary, generated by the default u-boot build, is now also bootable over USB in the FEL mode. The SPL still can boot from the SD card too. A bunch of system registers need to be saved/restored in order to ensure that the IRQ handler still works in the BROM FEL code after getting control back from the SPL. This is done in the sunxi code instead of abusing ifdefs in 'start.S'. The decision whether to load the main u-boot binary from the SD card or return to the FEL code in the BROM is done at runtime. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> [hdegoede@redhat.com: Since we now restore various regs before returning to the FEL BROM code we can drop the sunxi specific #ifdefs in start.S] Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
