set_pl310_ctrl_reg does use the Secure Monitor Call (SMC) to setup PL310 control register, however, that is something that is generic enough to be used for OMAP5 generation of processors as well. The only difference being the service being invoked for the function. So, convert the service to a macro and use a generic name (same as that used in Linux for some consistency). While at that, also add a data barrier which is necessary as per recommendation.

2015-03-09armv8/vexpress64: make multientry conditionalLinus Walleij
While the Freescale ARMv8 board LS2085A will enter U-Boot both on a master and a secondary (slave) CPU, this is not the common behaviour on ARMv8 platforms. The norm is that U-Boot is entered from the master CPU only, while the other CPUs are kept in WFI (wait for interrupt) state. The code determining which CPU we are running on is using the MPIDR register, but the definition of that register varies with platform to some extent, and handling multi-cluster platforms (such as the Juno) will become cumbersome. It is better to only enable the multiple entry code on machines that actually need it and disable it by default. Make the single entry default and add a special ARMV8_MULTIENTRY KConfig option to be used by the platforms that need multientry and set it for the LS2085A. Delete all use of the CPU_RELEASE_ADDR from the Vexpress64 boards as it is just totally unused and misleading, and make it conditional in the generic start.S code. This makes the Juno platform start U-Boot properly. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2015-03-09ARM: PSCI: Rework the DT handler slightlyTom Rini
The way the PSCI DT update happens currently means we pull in <asm/armv7.h> everywhere, including on ARMv8 and that in turn brings in <asm/io.h> for some non-PSCI related things that header needs to deal with. To fix this, we rework the hook slightly. A good portion of arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI is needed on ARMv8 we can re-use this by and large. So rename the current hook to psci_update_dt(), move the prototype to <asm/psci.h> and add an #ifdef that will make re-use later easier.

2015-03-09dlmalloc: do memset in malloc init as new default configPrzemyslaw Marczak
This commit introduces new config: CONFIG_SYS_MALLOC_CLEAR_ON_INIT. This config is an expert option and is enabled by default. The all amount of memory reserved for the malloc, is by default set to zero in mem_malloc_init(). When the malloc reserved memory exceeds few MiB, then the boot process can slow down. So disabling this config, is an expert option to reduce the boot time, and can be disabled by Kconfig. Note: After disable this option, only calloc() will return the pointer to the zeroed memory area. Previously, without this option, the memory pointed to untouched malloc memory region, was filled with zeros. So it means, that code with malloc() calls should be reexamined.

2015-03-09dfu: mmc: file buffer: remove static allocationPrzemyslaw Marczak
For writing files, DFU implementation requires the file buffer with the len at least of file size. For big files it requires the same big buffer. Previously the file buffer was allocated as a static variable, so it was a part of U-Boot .bss section. For 32MiB len of buffer we have 32MiB of additional space, required for this section. The .bss needs to be cleared after the relocation. This introduces an additional boot delay at every start, but usually the dfu feature is not required at the standard boot, so the buffer should be allocated only if required. This patch removes the static allocation of this buffer, and alloc it with memalign after first call of function: - dfu_fill_entity_mmc() and the buffer is freed on dfu_free_entity() call. This was tested on Trats2. A quick test with trace.

2015-03-09arm: relocation: clear .bss section with arch memset if definedPrzemyslaw Marczak
For ARM architecture, enable the CONFIG_USE_ARCH_MEMSET/MEMCPY, will highly increase the memset/memcpy performance. This is able thanks to the ARM multiple register instructions. Unfortunatelly the relocation is done without the cache enabled, so it takes some time, but zeroing the BSS memory takes much more longer, especially for the configs with big static buffers. A quick test confirms, that the boot time improvement after using the arch memcpy for relocation has no significant meaning. The same test confirms that enable the memset for zeroing BSS, reduces the boot time. So this patch enables the arch memset for zeroing the BSS after the relocation process. For ARM boards, this can be enabled in board configs by defining: 'CONFIG_USE_ARCH_MEMSET'. This was tested on Trats2. A quick test with trace.
