2015-01-26ARM: zynq: Enable the Neon instructionsMichal Simek
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.

Since commit 41623c91b09a0c865fab41acdaff30f060f29ad6 u-boot running in qemu is crashing in function do_omap3_emu_romcode_call(). RX-51 board uses this function for Cortex-A8 errata 430973 workaround (Set IBE bit in ACR) which is needed only on real secure device and not in qemu.

2015-01-09arc: introduce "mdbtrick" targetAlexey Brodkin
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.

2015-01-09mtd: nand: do not scan BBT after scrubMasahiro Yamada
Currently, "nand scrub" runs chip->scan_bbt at the end of nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set. It violates the intention of NAND_SKIP_BBTSCAN. Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set. Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt() right after scrub. We can be lazier here because the BBT is scanned at the next call of nand_block_checkbad().

2015-01-09mtd: nand: Mark the BBT as scanned prior to calling scan_bbt againMasahiro Yamada
Commit 35c204d8a9d0 (nand: reinstate lazy bad block scanning) broke NAND_BBT_USE_FLASH feature. Its git-log claimed that it reinstated the change as by commit fb49454b1b6c ("nand: reinstate lazy bad block scanning"), but it moved "chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);". It causes recursion if scan_bbt does not find a flash based BBT and tries to write one, and the attempt to erase the BBT area causes a bad block check.

2015-01-09arm: vf610: fix boot from SD-cardStefan Agner
Boot from SD-card (and probably also from NAND) was broken since commit d6d07a9bec ("arm: vf610: add NAND support for vf610twr"). It looks like the increased size of U-Boot lead to a situation where the boot ROM overwrote its own stack/heap while loading U-Boot from the SD-card to the SRAM. However, U-Boot worked fine when loaded through USB serial loader directly into SRAM. It looks like loading from SD-card uses other stack/heap location then the serial loader (or maybe no stack or heap at all). This fix moves U-Boot to gfxRAM, which is 512kB in size and is not used by the boot ROM nor the SD-card loader of it.

2015-01-09arm: build arch memset/memcpy in Thumb2 modeStefan Agner
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>

2015-01-09qspi:fsl implement AHB readPeng Fan
The QSPI controller in i.MX 6SoloX and Vybrid supports reading data using IP register and AHB bus. The original driver only supports reading data from IP interface. The IC team suggests to use AHB read which is faster then IP read. Using AHB read, we can directly memcpy, a "missed" access to the buffer will cause the controller to clear the buffer and use the SEQID stored in bfgencr register to initiate a read from flash device. Since AHB bus is 64 bit width, we can not set MCR register using 32bit. In order to minimize code change, redefine QSPI_MCR_END_CFD_LE to 64bit Little endian but not 32bit Little endia. Introduce a new configuration option CONFIG_SYS_FSL_QSPI_AHB. If want to use AHB read, just define CONFIG_SYS_FSL_QSPI_AHB. If not, just ignore it. Actually if Vybrid is migrated to use AHB read, this option can be removed and IP read function can be discared. The reason to introduce this option is that only i.MX SOC is tested in my side, no Vybrid platform for me. In spi_setup_slave, the original piece code to set AHB is deleted, since Vybrid platform does not use this to intiate AHB read. Instead, add qspi_init_ahb_read function if defined CONFIG_SYS_FSL_QSPI_AHB. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>

2015-01-07spi:fsl-quadspi support bank register read writePeng Fan
To support bigger than 16MB size qspi flashes, spi framework uses bank switch to access higher bank or lower bank. In this patch, QSPI_CMD_BRRD, QSPI_CMD_BRWR, QSPI_CMD_WREAR, QSPI_CMD_RDEAR is initialized in LUT register with related pad and length configuration. qspi_op_pp is originally for page programming, this patch reuses this function for bank register switch and renamed it with qspi_op_write. Since bank or EAR register is only 1 byte length, however original qspi_op_pp or now renamed qspi_op_write only support 4 bytes lenght as the access unit, this will trigger data abort exception when access EAR or bank register. This is because upper framework passes a 1 bytes pointer to qspi_op_write, however qspi_op_write treat it as an int pointer. This patch fixes this for accessing EAR or bank register.

2015-01-06spi: designware_spi: Fix detecting FIFO depthAxel Lin
Current code tries to find the highest valid fifo depth by checking the value it wrote to DW_SPI_TXFLTR. There are a few problems in current code: 1) There is an off-by-one in dws->fifo_len setting because it assumes the latest register write fails so the latest valid value should be fifo - 1. 2) We know the depth could be from 2 to 256 from HW spec, so it is not necessary to test fifo == 257. In the case fifo is 257, it means the latest valid setting is fifo = 256. So after the for loop iteration, we should check fifo == 2 case instead of fifo == 257 if detecting the FIFO depth fails.
