* arm: fsl: Adjust ordering of #ifndef CONFIG_SPL_BUILDSimon Glass2016-09-16-1/+2
| | | | | | | | | | | | The secure boot header files incorrectly define SPL options only if CONFIG_SPL_BUILD is defined. This means that the options are only enabled in an SPL build, and not with a normal 'make xxx_defconfig'. This means that moveconfig.py cannot work, since it sees the options as disabled even when they may be manually enabled in an SPL build. Fix this by changing the order.

* powerpc/mpc85xx: T104x: Add nand secure boot targetSumit Garg2016-07-21-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC. In non-secure boot scenario from NAND, this address will map to CPC configured as SRAM. But in case of secure boot, this default address always maps to IBR (Internal Boot ROM). The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF. For secure boot target from NAND, the text base for SPL is kept same as non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000) As a the virtual and physical address of CPC would be different. The virtual address 0xFFFx_xxxx needs to be mapped to physical address 0xBFFx_xxxx. Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000 and update DCFG SCRTACH1 register with location of Header required for secure boot. The changes are similar to commit 467a40dfe35f48d830f01a72617207d03ca85b4d powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041 While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC is only 256K and thus SPL framework is used. The changes are only applicable for SPL U-Boot running out of CPC SRAM and not the next level U-Boot loaded on DDR.

* Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass2016-03-14-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

* secure_boot: split the secure boot functionality in two partsAneesh Bansal2016-01-27-17/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two phases in Secure Boot 1. ISBC: In BootROM, validate the BootLoader (U-Boot). 2. ESBC: In U-Boot, continuing the Chain of Trust by validating and booting LINUX. For ESBC phase, there is no difference in SoC's based on ARM or PowerPC cores. But the exit conditions after ISBC phase i.e. entry conditions for U-Boot are different for ARM and PowerPC. PowerPC: If Secure Boot is executed, a separate U-Boot target is required which must be compiled with a diffrent Text Base as compared to Non-Secure Boot. There are some LAW and TLB settings which are required specifically for Secure Boot scenario. ARM: ARM based SoC's have a fixed memory map and exit conditions from BootROM are same irrespective of boot mode (Secure or Non-Secure). Thus the current Secure Boot functionlity has been split into two parts: CONFIG_CHAIN_OF_TRUST This will have the following functionality as part of U-Boot: 1. Enable commands like esbc_validate, esbc_halt 2. Change the environment settings based on bootmode, determined at run time: - If bootmode is non-secure, no change - If bootmode is secure, set the following: - bootdelay = 0 (Don't give boot prompt) - bootcmd = Validate and execute the bootscript. CONFIG_SECURE_BOOT This is defined only for creating a different compile time target for secure boot. Traditionally, both these functionalities were defined under CONFIG_SECURE_BOOT. This patch is aimed at removing the requirement for a separate Secure Boot target for ARM based SoC's. CONFIG_CHAIN_OF_TRUST will be defined and boot mode will be determine at run time. Another Security Requirement for running CHAIN_OF_TRUST is that U-Boot environemnt must not be picked from flash/external memory. This cannot be done based on bootmode at run time in current U-Boot architecture. Once this dependency is resolved, no separate SECURE_BOOT target will be required for ARM based SoC's. Currently, the only code under CONFIG_SECURE_BOOT for ARM SoC's is defining CONFIG_ENV_IS_NOWHERE Signed-off-by: Aneesh Bansal <aneesh.bansal@nxp.com> Acked-by: Ruchika Gupta <ruchika.gupta@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
