* armv8: enable compilation with CONFIG_SYS_NONCACHED_MEMORYStephen Warren2015-11-10-5/+6
| | | | | | | | | | | | | | | | The implementation of noncached_init() uses define MMU_SECTION_SIZE. Define this on ARM64. Move the prototype of noncached_{init,alloc}() to a location that doesn't depend on !defined(CONFIG_ARM64). Note that noncached_init() calls mmu_set_region_dcache_behaviour() which relies on something having set up translation tables with 2MB block size. The core ARMv8 MMU setup code does not do this by default, but currently relies on SoC specific MMU setup code. Be aware of this before enabling this feature on your platform!

* arm: stm32f4: fix a bug when a random sector gets erasedVadzim Dambrouski2015-11-10-0/+1
| | | | | | | | | | Old sector number is not being cleared from FLASH_CR register. For example when first erased sector was 001 and then you want to erase sector 010, sector 011 gets erased instead. This patch clears old sector number from FLASH_CR register before a new one is written. Signed-off-by: Vadzim Dambrouski <pftbest@gmail.com>
* arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILDAlbert ARIBAUD2015-11-10-0/+4
| | | | | | | | | | | | When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD, some files fail to build, most of the time because they include mcr instructions, which only exist for Thumb-2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the L2 AUX CTRL settings for the SoCFPGA. Enabling D and I prefetch bits helps improve SDRAM performance on the platform. Also, we need to enable bit 22 of the L2. By not having bit 22 set in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>

If found, and the loader ("fel" utility) provided a non-zero value for the boot.scr address, then the corresponding environment variable fel_scriptaddr gets set. misc_init_r() also sets (or clears) the "fel_booted" variable depending on the active boot device, using the same logic as spl_boot_device(). The goal is to provide sufficient information (within the U-Boot environment) to make intelligent decisions on how to continue the boot process, allowing specific customizations for the "FEL boot" case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch follows up on a discussion of ways to improve support for the sunxi FEL ("USB boot") mechanism, especially with regard to boot scripts, see: https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ The idea is to convert the (currently unused) "pad" bytes in the SPL header into an area where data can be passed to U-Boot. To do this safely, we have to make sure that we're actually using our "sunxi" flavor of the SPL, and not the Allwinner boot0. The modified mksunxiboot introduces a special signature to the SPL header in place of the "pub_head_size" field. This can be used to reliably distinguish between compatible versions of sunxi SPL and anything else (older variants or Allwinner's boot0).
