2020-04-24arm: asm/cache.c: Introduce arm_reserve_mmuOvidiu Panait
As a preparation for turning reserve_mmu into an arch-specific variant, introduce arm_reserve_mmu on ARM. It implements the default routine for reserving memory for MMU TLB and needs to be weakly defined in order to allow for machines to override it. Without this decoupling, after introducing arch_reserve_mmu, there would be two weak definitions for it, one in common/board_f.c and one in arch/arm/lib/cache.c.

2020-04-06arm64: versal: Disable DDR cache mapping if DDR is not enabledMichal Simek
Similar change was done in past by commit 3b644a3c2f69 ("arm64: zynqmp: Provide a config to not map DDR region in MMU table"). Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2020-01-17common: Move get_tbclk() to time.hSimon Glass
This function related to timer and most of the timer functions are in time.h, so move this function there. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-24arm64: xilinx: Move firmware functions from platform to driverMichal Simek
versal_pm_request() and invoke_smc() are almost the same. Only one difference is that versal_pm_request is adding PM_SIP_SVC offset to api_id. The patch is moving platform implementation to firmware driver code for synchronization. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Luca Ceresoli <luca@lucaceresoli.net>
2019-10-24arm64: versal: Clean pm_api_id usageMichal Simek
Copy enum values from platform code to firmware code. IDs are shared between ZynqMP and Versal. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2019-10-08clk: versal: Add clock driver supportSiva Durga Prasad Paladugu
This patch adds clock driver support for Versal platform. The clock driver queries and performs clock operations using PLM firmware by communicating with it using SMC calls.

2019-10-08arm64: zynqmp: Provide a Kconfig option to disable OCM and TCM MMU mappingMichal Simek
This patch provides an option to enable/disable OCM and TCM memory into MMU table with corresponding memory attributes. The same change was done for ZynqMP by commit 189bec47ab1f ("arm64: zynqmp: Provide a Kconfig option to define OCM and TCM in MMU") Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-10-08arm64: versal: Enable memory mapping via DTMichal Simek
Code reads DT and setup MMU table based on memory node. This will ensure that only DT needs to be changed. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2019-10-08arm64: versal: Define board_late_init for versalSiva Durga Prasad Paladugu
Define board_late_init which performs bootmode detection and prepares corresponding distro boot commaand sequence. Also disable it for mini platforms because simply there is no need to have it enabled. But also disable it for virtual platform because Qemu is not modelling this register space that's why travis testing would fail. This configuration should be reverted when mainline Qemu is updated.

2018-10-16arm64: versal: Add Xilinx Versal Virtual QEMU boardMichal Simek
Virtual QEMU board is generating DTB self and putting it to VERSAL_QEMU_DTB_ADDR address. Board is using CONFIG_OF_BOARD which ensures that u-boot is aligned with board created by QEMU. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2018-10-16arm64: versal: Add support for new Xilinx Versal ACAPsMichal Simek
Xilinx is introducing Versal, an adaptive compute acceleration platform (ACAP), built on 7nm FinFET process technology. Versal ACAPs combine Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent Engines with leading-edge memory and interfacing technologies to deliver powerful heterogeneous acceleration for any application. The Versal AI Core series has five devices, offering 128 to 400 AI Engines. The series includes dual-core Arm Cortex™-A72 application processors, dual-core Arm Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more than 1,900 DSP engines optimized for high-precision floating point with low latency. The patch is adding necessary infrastructure in place without enabling platform which is done in separate patch. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
