2017-11-28arm64: zynqmp: Provide a Kconfig option to use specified memory for MMU tableSiva Durga Prasad Paladugu
This patch provides a Kconfig option to use specified memory for MMU table using reserve_mmu platform specific routine. Here we used TCM space for MMU table. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-11-28arm64: zynqmp: remove unnecessary logical constraintHeinrich Schuchardt
In if (a || b) else if (!a) the constraint (!a) is always true if else is reached and can be removed. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-08-02arm64: zynqmp: Remove ifdef around zynqmp mmio read and write rotuinesSiva Durga Prasad Paladugu
This patch removes ifdef around mmio read and write rotuines and make them a single routine by checking the current el. This patch helps to remove ifdef around invoke_smc as well. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-08-02arm64: zynqmp: Provide a Kconfig option to define OCM and TCM in MMUSiva Durga Prasad Paladugu
This patch provides an option to include OCM and TCM memory into MMU table with corresponding memory attributes. Signed-off-by: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-06-20arm64: zynqmp: Check pmufw versionMichal Simek
If PMUFW version is not v0.3 then panic. ZynqMP switch to CCF based clock driver which requires PMUFW to be present at certain version. This patch ensure that you use correct and tested PMUFW binary. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2017-06-20arm64: zynqmp: Define routines for mmio write and readSiva Durga Prasad Paladugu
Define routines of mmio write and read functionalities for zynqmp platform. Also do not call SMC from SPL because SPL is running before ATF in EL3 that's why SMCs can't be called because there is nothing to call. zynqmp_mmio*() are doing direct read/write accesses and this patch does the same. PMUFW is up and running at this time and there is a way to talk to pmufw via IPI but there is no reason to implement IPI stuff in SPL if we need just simple read for getting clock driver to work. Also make invoke_smc as global so that it can be reused in multile places where ever possible.

2017-06-20arm64: zynqmp: Do not map unused OCM/TCM regionMichal Simek
When OCM or TCM is protected this mapping still exist and it is causing access violation. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2016-07-15armv8: mmu: Add support of non-identical mappingYork Sun
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>
2016-06-06ARM64: zynqmp: Extend page_table_sizeMichal Simek
0xc000 is not sufficient page table size if dc4 with 4 gems is enabled. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2016-03-15zymqmp: Replace home grown mmu code with generic table approachAlexander Graf
Now that we have nice table driven page table creating code that gives us everything we need, move to that. Signed-off-by: Alexander Graf <agraf@suse.de>
2016-01-27ARM64: zynqmp: Add initial support for the first siliconMichal Simek
Add basic configuration for the first silicon. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2016-01-27ARM64: zynqmp: Use the same U-Boot version with/without ATFMichal Simek
Remove SECURE_IOU option which is not needed. U-Boot itself can detect which EL level it is on and based on that use do platform setup. It also simplify usage because one Kconfig entry is gone. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2015-08-19ARM: zynqmp: Add platform specific arch_get_page_tableMichal Simek
Based on the patch: "armv8: caches: Added routine to set non cacheable region" (sha1: dad17fd51027ad02ac8f02deed186d08109d61fd) it is necessary to add platform specific hook. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
