2016-12-05arm64: mvebu: Restrict memory size to a usable maximumStefan Roese
Not all memory is mapped in the MMU. So we need to restrict the memory size so that U-Boot does not try to access it. Also, the internal registers are located at 0xf000.0000 - 0xffff.ffff. Currently only 2GiB are mapped for system memory. This is what we pass to the U-Boot subsystem here.

2016-12-04ARM: DRA7: Fixup DSPEVE, IVA and GPU clock frequencies based on OPPSuman Anna
This patch adds support to update the device-tree blob to adjust the DSP and IVA DPLL clocks pertinent to the selected OPP choice, with the default being OPP_NOM. The voltage settings are done in u-boot, but the actual clock configuration itself is done in kernel because of the following reasons: 1. SoC definition constraints us to NOT to do dynamic voltage scaling ever after the initial avs0 setting in bootloader - so the voltage must be set in bootloader. 2. The voltage level must be set even if the IP blocks like GPU/DSP are unused. 3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality, and similar DPLL clock configuration code has been cleaned up in v2014.10 u-boot release. See commit, 02c41535b6a4 ("ARM: OMAP4/5: Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL"). The non-essential DPLLs are configured within the kernel during the clock init step when parsing the device tree and creating the clock devices. This approach meets both the u-boot and kernel needs.

2016-12-04ARM: DRA7: Redefine voltage and efuse macros per OPP using KconfigSuman Anna
Redefine the macros used to define the voltage values and the efuse register offsets based on OPP for all the voltage domains. This is done using Kconfig macros that can be set in a defconfig or selected during a config step. This allows a voltage domain to be configured/set to a corresponding voltage value depending on the OPP selection choice. The Kconfig choices have been added for MPU, DSPEVE, IVA and GPU voltage domains, with the MPU domain restricted to OPP_NOM. The OPP_OD and OPP_HIGH options will be added when the support for configuring the MPU clock frequency is added. The clock configuration for other voltage domains is out of scope in u-boot code. The CORE voltage domain does not have separate voltage values and efuse register offset at different OPPs, while the MPU voltage domain only has different efuse register offsets for different OPPs, but uses the same voltage value. Any different choices of OPPs for voltage domains on common ganged-rails is automatically taken care to select the corresponding highest OPP voltage value.

secure_tee_install is used to install and initialize a secure TEE OS such as Linaro OP-TEE into the secure world. This function takes in the address where the signed TEE image is loaded as an argument. The signed TEE image consists of a header (struct tee_header), TEE code+data followed by the signature generated using image signing tool from TI security development package (SECDEV). Refer to README.ti-secure for more information. This function uses 2 new secure APIs. 1. PPA_SERV_HAL_TEE_LOAD_MASTER - Must be called on CPU Core 0. Protected memory for TEE must be reserved before calling this function. This API needs arguments filled into struct ppa_tee_load_info. The TEE image is authenticated and if there are no errors, the control passes to the TEE entry point. 2. PPA_SERV_HAL_TEE_LOAD_SLAVE - Called on other CPU cores only after a TEE_LOAD_MASTER call. Takes no arguments. Checks if TEE was successfully loaded (on core 0) and transfers control to the same TEE entry point.
