Android's tool chain enable the -mandroid at default. This option will enable the -fpic, which cause uboot compilation failure: " LD u-boot u-boot contains unexpected relocations: R_ARM_ABS32 R_ARM_RELATIVE " In my testcase, arm-linux-androideabi-gcc-4.9 internally enables '-fpic', so when compiling code, there will be relocation entries using type R_ARM_GOT_BREL and .got section. When linking all the built-in.o using ld, there will be R_ARM_ABS32 relocation entry and .got section in the final u-boot elf image. This can not be handled by u-boot, since u-boot only expects R_ARM_RELATIVE relocation entry. arm-poky-linux-gnueabi-gcc-4.9 default does not enable '-fpic', so there is not .got section and R_ARM_GOT_BREL in built-in.o. And in the final u-boot elf image, all relocation entries are R_ARM_RELATIVE. we can pass '-fno-pic' to xxx-gcc to disable pic. whether the toolchain internally enables or disables pic, '-fno-pic' can work well.

Change absolute address to RelAdr. Based on LDR (immediate, ARM), we only have 4K offset to jump. Now PSCI code size is close to 4K size that is LDR limit jump size, so even if the LDR is based on the current instruction address, there is also have a risk for RelAdr. If we use two jump steps I think we can fix this issue, but looks too hack, so give up this way. 2. Enable "DISCARD" only for CONFIG_ARMV7_SECURE_BASE has defined. If CONFIG_ARMV7_SECURE_BASE is defined in platform, all of secure will in the BASE address that is absolute.

2016-01-31arm: Replace test for CONFIG_ARMV7 with CONFIG_CPU_V7Marek Vasut
The arch/arm/lib/cache-cp15.c checks for CONFIG_ARMV7 and if this macro is set, it configures TTBR0 register. This register must be configured for the cache on ARMv7 to operate correctly. The problem is that noone actually sets the CONFIG_ARMV7 macro and thus the TTBR0 is not configured at all. On SoCFPGA, this produces all sorts of minor issues which are hard to replicate, for example certain USB sticks are not detected or QSPI NOR sometimes fails to write pages completely. The solution is to replace CONFIG_ARMV7 test with CONFIG_CPU_V7 one. This is correct because the code which added the test(s) for CONFIG_ARMV7 was added shortly after CONFIG_ARMV7 was replaced by CONFIG_CPU_V7 and this code was not adjusted correctly to reflect that change.

2016-01-28ARM: tegra: shut down USB device controller at bootStephen Warren
When loading U-Boot into RAM over USB protocols using tools such as tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device mode controller is initialized and enumerated by the host PC running the tool. Unfortunately, these tools do not shut down the USB controller before executing the downloaded code, and so the host PC does not "de-enumerate" the USB device. This patch implements optional code to shut down the USB controller when U-Boot boots to avoid leaving a stale USB device present.

2016-01-27secure_boot: split the secure boot functionality in two partsAneesh Bansal
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>
