2016-07-20mx6: clock: Fix the logic for reading axi_alt_selFabio Estevam
According to the IMX6DQRM Reference Manual, the description of bit 7 (axi_alt_sel) of the CCM_CBCDR register is: "AXI alternative clock select 0 pll2 396MHz PFD will be selected as alternative clock for AXI root clock 1 pll3 540MHz PFD will be selected as alternative clock for AXI root clock " The current logic is inverted, so fix it to match the reference manual.

2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

2016-06-20sunxi: Add PSCI implementation in CChen-Yu Tsai
To make the PSCI backend more maintainable and easier to port to newer SoCs, rewrite the current PSCI implementation in C. Some inline assembly bits are required to access coprocessor registers. PSCI stack setup is the only part left completely in assembly. In theory this part could be split out of psci_arch_init into a separate common function, and psci_arch_init could be completely in C.

2016-05-27spl: build: ti: add support for secure boot imagesDaniel Allred
Updates the SPL build so that when CONFIG_TI_SECURE_DEVICE is in use (which it should be when building for secure parts), the TI secure development package is used to create a valid secure boot image. The u-boot SPL build processes is NOT aware of the details of creating the boot image - all of that information is encapsulated in the TI secure development package, which is available from TI. More info can be found in README.ti-secure Right now, two image types are generated, MLO and X-LOADER. The types are important, as certain boot modes implemented by the device's ROM boot loader require one or the other (they are not equivalent). The output filenames are u-boot-spl_HS_MLO and u-boot-spl_HS_X-LOADER. The u-boot-spl_HS_MLO image is also copied to a file named MLO, which is the name that the device ROM bootloader requires for loading from the FAT partition of an SD card (same as on non-secure devices).

Adds a new Kconfig file for AM33xx class devices. We need a common place to define CONFIG parameters for these SOCs, especially for adding support for secure devices. a) Adds a definition for ISW_ENTRY_ADDR. This is the address to which the ROM branches when the SOC ROM hands off execution to the boot loader. CONFIG_SYS_TEXT_BASE and CONFIG_SPL_TEXT_BASE are set to this value for AM43xx devices. b) Adds CONFIG_PUB_ROM_DATA_SIZE which is used to calculate CONFIG_SPL_MAX_SIZE. This value indicates the amount of memory needed by the ROM to store data during the boot process. Currently, these CONFIG options are used only by AM43xx, but in future other AM33xx class SOCs will also use them.
