* | tools: mkimage: Add support for initialization table for Zynq and ZynqMPMike Looijmans2016-11-15-0/+14
|/ | | | | | | | | | | | | | | | | | The Zynq/ZynqMP boot.bin file contains a region for register initialization data. Filling in proper values in this table can reduce boot time (e.g. about 50ms faster on QSPI boot) and also reduce the size of the SPL binary. The table is a simple text file with register+data on each line. Other lines are simply skipped. The file can be passed to mkimage using the "-R" parameter. It is recommended to add reg init file to board folder. For example: CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* arm: Set TTB XN bit in case DCACHE_OFF for LPAE modeKeerthy2016-11-13-1/+6
| | | | | | | | | | | | | | | | | While we setup the mmu initially we mark set_section_dcache with DCACHE_OFF flag. In case of non-LPAE mode the DCACHE_OFF macro is rightly defined with TTB_SECT_XN_MASK set so as to mark all the 4GB XN. In case of LPAE mode XN(Execute-never) bit is not set with DCACHE_OFF. Hence XN bit is not set by default for DCACHE_OFF which keeps all the regions execute okay and this leads to random speculative fetches in random memory regions which was eventually caught by kernel omap-l3-noc driver. Fix this to mark the regions as XN by default. Signed-off-by: Keerthy <j-keerthy@ti.com> Reviewed-by: Alexander Graf <agraf@suse.de> Reviewed-by: Tom Rini <trini@konsulko.com>

| * ARM: tegra: translate __asm_flush_l3_cache to assemblyStephen Warren2016-11-07-23/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When performing a cache disable function, code must not access DRAM. That is because when the cache is disabled, it will be bypassed and all loads and stores will be serviced by RAM. This prevents accessing any dirty data in the cache. In turn, this means the stack cannot be used, since that is in RAM. To guarantee that code doesn't use RAM (and in particular the stack) __asm_flush_l3_cache() must be manually implemented in assembly, rather than implemented in C since the compiler won't know not to touch RAM.

* armv8: define get_ticks() for the ARMv8 Generic TimerAndre Przywara2016-11-05-0/+11
| | | | | | | | | | | | | | | | | | | For 64-bit ARM systems we provide just a timer_read_counter() implementation and rely on the generic non-uclass get_ticks() function in lib/time.c to call the former. However this function is actually not 64-bit safe, as it assumes a "long" to be 32-bit. Beside the fact that the resulting uint64_t isn't bigger than "long" on 64-bit architectures and thus combining two counters makes no sense, we get all kind of weird results when we try to OR in the high value shifted by _32_ bits. So let's avoid that function at all and provide a straight forward get_ticks() implementation for ARMv8, which also is in line with ARMv7. This fixes occasional immediate time-out expiration issues I see on the Pine64 board. The root cause of this needs to be investigated, but this fix looks like the right thing anyway.
