2016-11-29ARM: mx6: ddr: use Kconfig for inclusion of DDR calibration routinesEric Nelson
The DDR calibration routines are gated by conditionals for the i.MX6DQ SOCs, but with the use of the sysinfo parameter, these are usable on at least i.MX6SDL and i.MX6SL variants with DDR3. Also, since only the Novena board currently uses the dynamic DDR calibration routines, these routines waste space on other boards using SPL. Add a KConfig entry to allow boards to selectively include the DDR calibration routines. Signed-off-by: Eric Nelson <eric@nelint.com>
2016-11-29mx6: ddr: add routine to return DDR calibration dataEric Nelson
Add routine mmdc_read_calibration() to return the output of DDR calibration. This can be used for debugging or to aid in construction of static memory configuration. This routine will be used in a subsequent patch set adding a virtual "mx6memcal" board, but could also be useful when gathering statistics during an initial production run.

2016-11-29mx6: ddr: pass mx6_ddr_sysinfo to calibration routinesEric Nelson
The DDR calibration routines have scattered support for bus widths other than 64-bits: -- The mmdc_do_write_level_calibration() routine assumes the presence of PHY1, and -- The mmdc_do_dqs_calibration() routine tries to determine whether one or two DDR PHYs are active by reading MDCTL. Since a caller of these routines must have a valid struct mx6_ddr_sysinfo for use in calling mx6_dram_cfg(), and the bus width is available in the "dsize" field, use this structure to inform the calibration routines which PHYs are active. This allows the use of the DDR calibration routines on CPU variants like i.MX6SL that only have a single MMDC port.

2016-11-29mx6: ddr: allow 32 cycles for DQS gating calibrationEric Nelson
The DDR calibration code is only setting flag DG_CMP_CYC (DQS gating sample cycle) for the first PHY. Set the 32-cycle flag for both PHYs and clear when done so the MPDGCTRL0 output value isn't polluted with calibration artifacts.

2016-11-29armv7: psci: cpu_off: flush D-Cache before disable D-CachePeng Fan
Before disable cache, need to first flush cache. There maybe dirty data in D-Cache before disable D-Cache. After disable D-Cache, the first store instructions in psci_v7_flush_dcache_all will directly store registers {r4-r5, r7, r9-r11, lr} to memory. If there is dirty data before disable D-Cache, psci_v7_flush_dcache_all will flush data to memory, and may overwrite the memory that hold the registers {r4-r5, r7, r9-r11, lr}. So before disable cache, first flush D-Cache.

2016-11-28arm: sunxi: do not force USB for arch-sunxiYann E. MORIN
Currently, USB is forced-enabled for the sunxi familly, and there is no way to disable it. However, USB takes a long time to initiliase, delaying the boot by up to 5 seconds (without any USB device attached!). This is a very long delay, especially in cases where USB booting is not wanted at all, and where the device is expected to boot relatively often (even in production). Change the way the dependencies are handled, by only forcibly selecting USB when CONFIG_DISTRO_DEFAULTS ("defaults suitable for booting general purpose Linux distributions") is set. This option defaults to y for the sunxi familly, so the current default behaviour is kept unchanged. Users interested in boot time and/or size will be able to disable this to further disable USB. With USB disabled, the time spent in U-Boot before handing control to the Linux kernel is about 1s now, down from ~5s (Nanopi Neo, sunxi H3). Signed-off-by: "Yann E.

2016-11-27efi_loader: Allow to compile helloworld.efi w/o bundling itAlexander Graf
Today we can compile a self-contained hello world efi test binary that allows us to quickly verify whether the EFI loader framwork works. We can use that binary outside of the self-contained test case though, by providing it to a to-be-tested system via tftp. This patch separates compilation of the helloworld.efi file from including it in the u-boot binary for "bootefi hello". It also modifies the efi_loader test case to enable travis to pick up the compiled file. Because we're now no longer bloating the resulting u-boot binary, we can enable compilation always, giving us good travis test coverage.

Remove the custom low-level initialization function and reuse the default low-level initialization function. But this requires the ARMV8_MULTIENTRY config option to be enabled for Exynos7420. On Exynos7420, the boot CPU belongs to the second cluster and so with ARMV8_MULTIENTRY config option enabled, the 'branch_if_master' macro fails to detect the CPU as boot CPU. As a temporary workaround the CPU_RELEASE_ADDR is set to point to '_main'.
