2014-07-31ahci: provide sunxi SATA driver using AHCI platform frameworkIan Campbell
This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done for sun7i only since I don't have access to any other sunxi platforms with sata included. The PHY setup is derived from the Alwinner releases and Linux, but is mostly undocumented. The Allwinner AHCI controller also requires some magic (and, again, undocumented) DMA initialisation when starting a port. This is added under a suitable ifdef. This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on contents of Linux DTS files, including SATA power pin config taken from the DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

2014-07-28ARM: HYP/non-sec: remove MIDR check to validate CBARMarc Zyngier
Having a form of whitelist to check if we know of a CPU core and and obtain CBAR is a bit silly. It doesn't scale (how about A12, A17, as well as other I don't know about?), and is actually a property of the SoC, not the core. So either it works and everybody is happy, or it doesn't and the u-boot port to this SoC is providing the real address via a configuration option. The result of the above is that this code doesn't need to exist, is thus forcefully removed. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2014-07-28ARM: HYP/non-sec: allow relocation to secure RAMMarc Zyngier
The current non-sec switching code suffers from one major issue: it cannot run in secure RAM, as a large part of u-boot still needs to be run while we're switched to non-secure. This patch reworks the whole HYP/non-secure strategy by: - making sure the secure code is the *last* thing u-boot executes before entering the payload - performing an exception return from secure mode directly into the payload - allowing the code to be dynamically relocated to secure RAM before switching to non-secure. This involves quite a bit of horrible code, specially as u-boot relocation is quite primitive. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2014-07-25ARM: omap: fix GPMC address-map size for NAND and NOR devicespekon gupta
Fixes commit a0a37183bd75e74608bc78c8d0e2a34454f95a91 ARM: omap: merge GPMC initialization code for all platform 1) NAND device are not directly memory-mapped to CPU address-space, they are indirectly accessed via following GPMC registers: - GPMC_NAND_COMMAND_x - GPMC_NAND_ADDRESS_x - GPMC_NAND_DATA_x Therefore from CPU's point of view, NAND address-map can be limited to just above register addresses. But GPMC chip-select address-map can be configured in granularity of 16MB only. So this patch uses GPMC_SIZE_16M for all NAND devices. 2) NOR device are directly memory-mapped to CPU address-space, so its address-map size depends on actual addressable region in NOR FLASH device. So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map size configuration. Signed-off-by: Pekon Gupta <pekon@ti.com>

The errata is applicable on all OMAP4 (4430 and 4460/4470) and OMAP5 ES 1.0 devices. The current revision check erroneously implements this on all DRA7 varients and with DRA722 device (which has only 1 EMIF instance) infact causes an asynchronous abort and ends up masking it in CPSR, only to be uncovered once the kernel switches to userspace.

2014-07-25k2hk: use common KS2_ prefix for all hardware definitionsKhoronzhuk, Ivan
Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and add KS2_ prefix where it's needed. It requires to change names also in places where they're used. Align lines and remove redundant definitions in kardware-k2hk.h at the same time. Using common KS2_ prefix helps resolve redundant redefinitions and adds opportunity to use KS2_ definition across a project not thinking about what SoC should be used. It's more convenient and we don't need to worry about the SoC type in common files, hardware.h will think about that. The hardware.h decides definitions of what SoC to use.
