* ARM: zynq: Enable the Neon instructionsMichal Simek2015-01-26-3/+34
| | | | | | | | | | | | | | | | | | Added the lowlevel_init to enable the Neon instructions. Initially the u-boot was causing undefined instruction exception if loaded through tcl, and working fine if loaded through FSBL. The exception was causing in convertion formula of given time to ticks. It was because, the Neon instructions were disabled and hence causing the undefined exception. In FSBL case, the FSBL was enabling the Neon instructions. Hence, added the lowlevel_init to enable the Neon instructions. Also enable neon instructions for non-xilinx toolchain.

* arc: introduce "mdbtrick" targetAlexey Brodkin2015-01-09-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MetaWare debugger (MDB) is still used as a primary tool for interaction with target via JTAG. Moreover some very advanced features are not yet implemented in GDB for ARC (and not sure if they will be implemnted sometime soon given complexity and rare need for those features for common user). So if we're talking about development process when U-Boot is loaded in target memory not by low-level boot-loader but manually through JTAG chances are high developer uses MDB for it. But MDB doesn't support PIE (position-independent executable) - it will refuse to even start - that means no chance to load elf contents on target. Then the only way to load U-Boot in MDB is to fake it by: 1. Reset PIE flag in ELF header This is simpe - on attempt to open elf MDB checks header and if it doesn't match its expectation refuces to use provided elf. 2. Strip all debug information from elf If (1) is done then MDB will open elf but on parsing of elf's debug info it will refuse to process due to debug info it cannot understand (symbols with PIE relocation). Even though it could be done manually (I got it documented quite a while ago here http://www.denx.de/wiki/U-Boot/ARCNotes) having this automated way is very convenient. User may build U-Boot that will be loaded on target via MDB saying "make mdbtrick". Then if we now apply the manipulation MDB will happily start and will load all required sections into the target. Indeed there will be no source-level debug info available. But still MDB will do its work on showing disassembly, global symbols, registers, accessing low-level debug facilities etc. As a summary - this is a pretty dirty hack but it simplifies life a lot for us ARc developers.

* arm: build arch memset/memcpy in Thumb2 modeStefan Agner2015-01-09-87/+142
| | | | | | | | | | | | | | | | | | | | | | Resynchronize memcpy/memset with kernel 3.17 and build them in Thumb2 mode (unified syntax). Those assembler files can be built and linked in ARM mode too, however when calling them from Thumb2 built code, the stack got corrupted and the copy did not succeed (the exact details have not been traced back). However, the Linux kernel builds those files in Thumb2 mode. Hence U-Boot should build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set. To build the files without warning, some assembler instructions had to be replaced with their UAL compliant variant (thanks Jeroen for this input). To build the file in Thumb2 mode the implicit-it=always option need to be set to generate Thumb2 compliant IT instructions where needed. We add this option to the general AFLAGS when building for Thumb2. Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stefan Agner <stefan@agner.ch>

* | ARM: bootm: do not add PSCI to fdt when booting in secure mode.Ian Campbell2015-01-05-2/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable systems" added the capability to select nonsec vs sec mode boot via an environment var. There is a subtle gotcha with this functionality, which is that the PSCI nodes are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting in secure mode. Which means that if the kernel is PSCI aware then it will fail to boot because it will try and do PSCI from secure world, which won't work. This likely didn't get noticed before because the original purpose was to support booting the legacy linux-sunxi kernels which don't understand PSCI. To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and use from the virt-dt code. As well as avoiding the creation of the PSCI nodes we should also avoid reserving the secure RAM, so do so.
