| * armv8: fsl-lsch3: Disable SMMU during secure bootSaksham Jain2016-03-291-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | During secure boot, SMMU is enabled on POR by SP bootrom. SMMU needs to be put in bypass mode in uboot to enable CAAM transcations to pass through. For non-secure boot, SP BootROM doesn't enable SMMU, which is in bypass mode out of reset.

* | arm: Add support for HYP mode and LPAE page tablesAlexander Graf2016-03-271-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently always modify the SVC versions of registers and only support the short descriptor PTE format. Some boards however (like the RPi2) run in HYP mode. There, we need to modify the HYP version of system registers and HYP mode only supports the long descriptor PTE format. So this patch introduces support for both long descriptor PTEs and HYP mode registers. Signed-off-by: Alexander Graf <agraf@suse.de>

* | ARM: OMAP5/DRA7: Split iodelay functionality into sub stepsNishanth Menon2016-03-271-14/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since many platforms may need different pad configuration required depending on variation of the platform with minor deltas, it is easier to maintain a sub step based approach to allow for pin mux and iodelay configuration which may depend on the platform variations and need to be done in IO isolation. While we retain the older __recalibrate_iodelay function which provides a ready sequencing, __recalibrate_iodelay_start and __recalibrate_iodelay_end may be alternatively used now and the callers will be responsible for the correct sequencing of operations.

* | sunxi: Fix gmac not working due to cpu_eth_init no longer being calledHans de Goede2016-03-231-27/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpu_eth_init is no longer called for dm enabled eth drivers, this was causing the sunxi gmac eth controller to no longer work in u-boot. This commit fixes this by calling the clock, reset and pinmux setup function from s_init() and enabling the phy power pin (if any) from board_init(). The enabling of phy power cannot be done from s_init because it uses dm and dm is not ready yet at this point. Note that the mdelay is dropped as the phy gets enabled much earlier now, so it is no longer needed.

On the Layerscape SoCs however, we just provide an empty table stub and do the setup ourselves. To reserve enough memory for the tables, we need to override the default counting mechanism which would end up with an empty table because we have no maps.

* arm64: Allow exceptions to returnAlexander Graf2016-03-151-0/+34
| | | | | | | | | | | | | | Our current arm64 exception handlers all panic and never return to the exception triggering code. But if any handler wanted to continue execution after fixups, it would need help from the exception handling code to restore all registers. This patch implements that help. With this code, exception handlers on aarch64 can successfully return to the place the exception happened (or somewhere else if they modify elr). Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: Add runtime servicesAlexander Graf2016-03-152-0/+46
| | | | | | | | | | | | | | | | | After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.

* arm64: Make full va map code more dynamicAlexander Graf2016-03-152-55/+452
| | | | | | | | | | | | | | | | | | | The idea to generate our pages tables from an array of memory ranges is very sound. However, instead of hard coding the code to create up to 2 levels of 64k granule page tables, we really should just create normal 4k page tables that allow us to set caching attributes on 2M or 4k level later on. So this patch moves the full_va mapping code to 4k page size and makes it fully flexible to dynamically create as many levels as necessary for a map (including dynamic 1G/2M pages). It also adds support to dynamically split a large map into smaller ones when some code wants to set dcache attributes. With all this in place, there is very little reason to create your own page tables in board specific files. Signed-off-by: Alexander Graf <agraf@suse.de>

| | | | | | | | | | | | When running in EL1, AArch64 knows two page table maps. One with addresses that start with all zeros (TTBR0) and one with addresses that start with all ones (TTBR1).
