* armv8: mmu: Add support of non-identical mappingYork Sun2016-07-15-2/+4
| | | | | | | Introduce virtual and physical addresses in the mapping table. This change have no impact on existing boards because they all use idential mapping. Signed-off-by: York Sun <york.sun@nxp.com>
* vexpress64: Add MMU tablesAlexander Graf2016-03-15-0/+21
| | | | | | | | There's no good excuse for running with caches disabled on AArch64, so let's just move the vexpress64 target to enable the MMU and run with caches on. Signed-off-by: Alexander Graf <agraf@suse.de>
* vexpress64: use 2nd DRAM bank only on junoRyan Harkin2015-11-21-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the 2nd DRAM bank available on Juno only and not on other vexpress64 targets, eg. the FVP models. The commit below added a 2nd bank of NOR flash for Juno, but also for all vexpress64 targets: commit 2d0cee1ca2b9d977fa3214896bb2e30cfec77059 Author: Liviu Dudau <Liviu.Dudau@foss.arm.com> Date: Mon Oct 19 11:08:31 2015 +0100 vexpress64: Juno: Declare all 8GB of RAM and make them visible to the kernel.

* vexpress64: fvp dram: add DRAM configurationRyan Harkin2015-10-11-1/+6
| | | | | | | | | | | | | | | | | | | | Create an additional FVP configuration to boot images pre-loaded into DRAM. Sometimes it's preferential to boot the model by loading the files directly into DRAM via model parameters, rather than using SemiHosting. An example of model parmaters that are used to pre-load the files into DRAM: --data cluster0.cpu0=Image@0x80080000 \ --data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \ --data cluster0.cpu0=uInitrd@0x84000000 Signed-off-by: Ryan Harkin <ryan.harkin@linaro.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> [trini: Update board/armltd/vexpress64/Kconfig logic] Signed-off-by: Tom Rini <trini@konsulko.com>

* vexpress64: use DM for all vexpress64 boardsLinus Walleij2015-04-23-1/+1
| | | | | | | | | | | | | | | | | | Commit d8bafe1310487ba0e0785997726b4792072178d3 "ARMv8: enable DM in vexpress64 board" only enabled DM for the simulated vexpress64 board (FVP) with the hardcoded clock value for the simulated board, causing a console regression on the Juno board which was using a different clock setting. Fix this by enabling DM for all vexpress64 boards, defining the clock frequency per-board, deleting the static array of PL01x ports from the config file and relying solely on the port defined in the boardfile using platform data.

* armv8/vexpress64: make multientry conditionalLinus Walleij2015-03-09-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | While the Freescale ARMv8 board LS2085A will enter U-Boot both on a master and a secondary (slave) CPU, this is not the common behaviour on ARMv8 platforms. The norm is that U-Boot is entered from the master CPU only, while the other CPUs are kept in WFI (wait for interrupt) state. The code determining which CPU we are running on is using the MPIDR register, but the definition of that register varies with platform to some extent, and handling multi-cluster platforms (such as the Juno) will become cumbersome. It is better to only enable the multiple entry code on machines that actually need it and disable it by default. Make the single entry default and add a special ARMV8_MULTIENTRY KConfig option to be used by the platforms that need multientry and set it for the LS2085A. Delete all use of the CPU_RELEASE_ADDR from the Vexpress64 boards as it is just totally unused and misleading, and make it conditional in the generic start.S code. This makes the Juno platform start U-Boot properly. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* vexpress64: support the Juno Development PlatformLinus Walleij2015-01-30-0/+18
| | | | | | | | | | The Juno Development Platform is a physical Versatile Express device with some differences from the emulated semihosting models. The main difference is that the system is split in a SoC and an FPGA where the SoC hosts the serial ports at totally different adresses. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* vexpress64: get rid of CONFIG_SYS_EXTRA_OPTIONSLinus Walleij2015-01-30-1/+14
| | | | | | | | | | | | | | | | | | | | The Versatile Express ARMv8 semihosted FVP platform is still using the legacy CONFIG_SYS_EXTRA_OPTIONS method to configure some compile-time flags. Get rid of this and create a Kconfig entry for the FVP model, and a selectable bool for the semihosting library. The FVP subboard is now modeled as a target choice so we can eventually choose between different ARMv8 versatile express boards (FVP, base model, Juno...) this way. All dependent symbols are updated to reflect this. The 64bit Versatile Express board symbols are renamed VEXPRESS64 so we have some chance to see what is actually going on. Tested on the FVP fast model. Acked-by: Steve Rae <srae@broadcom.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+11
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-5/+96
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.
