ARMv8/layerscape: Add FSL PPA support

2016-07-19T18:33:53Z

The FSL Primary Protected Application (PPA) is a software component loaded during boot which runs in TrustZone and remains resident after boot. Use the secure firmware framework to integrate FSL PPA into U-Boot. Signed-off-by: Hou Zhiqiang Reviewed-by: York Sun

ARMv8: add the secure monitor firmware framework

2016-07-19T18:33:03Z

This framework is introduced for ARMv8 secure monitor mode firmware. The main functions of the framework are, on EL3, verify the firmware, load it to the secure memory and jump into it, and while it returned to U-Boot, do some necessary setups at the 'target exception level' that is determined by the respective secure firmware. So far, the framework support only FIT format image, and need to define the name of which config node should be used in 'configurations' and the name of property for the raw secure firmware image in that config. The FIT image should be stored in Byte accessing memory, such as NOR Flash, or else it should be copied to main memory to use this framework. Signed-off-by: Hou Zhiqiang Reviewed-by: York Sun

armv8: mmu: Add support of non-identical mapping

2016-07-15T16:01:43Z

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

armv8: mmu: house cleaning

2016-07-15T16:01:43Z

Make setup_pgtages() and get_tcr() available for platform code to customize MMU tables. Remove unintentional call of create_table(). Signed-off-by: York Sun

arm64: Remove non-full-va map code

2016-03-15T19:13:10Z

By now the code to only have a single page table level with 64k page size and 42 bit address space is no longer used by any board in tree, so we can safely remove it. To clean up code, move the layerscape mmu code to the new defines, removing redundant field definitions. Signed-off-by: Alexander Graf

thunderx: Move mmu table into board file

2016-03-15T19:13:02Z

The MMU range table can vary depending on things we may only find out at runtime. While the very simple ThunderX variant does not change, other boards will, so move the definition from a static entry in a header file to the board file. Signed-off-by: Alexander Graf

arm64: Make full va map code more dynamic

2016-03-15T19:13:01Z

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

arm64: Disable TTBR1 maps in EL1

2016-03-15T19:13:00Z

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). In U-Boot we don't care about the high up maps, so just disable them to ensure we don't walk an invalid page table by accident. Reported-by: Mark Rutland Signed-off-by: Alexander Graf

thunderx: Calculate TCR dynamically

2016-03-15T19:12:59Z

Based on the memory map we can determine a lot of hard coded fields of TCR, like the maximum VA and max PA we want to support. Calculate those dynamically to reduce the chance for pit falls. Signed-off-by: Alexander Graf

armv8: New MMU setup code allowing to use 48+ bits PA/VA

2016-01-19T22:25:36Z

This patch adds code which sets up 2-level page tables on ARM64 thus extending available VA space. CPUs implementing 64k translation granule are able to use direct PA-VA mapping of the whole 48 bit address space. It also adds the ability to reset the SCTRL register at the very beginning of execution to avoid interference from stale mappings set up by early firmware/loaders/etc. Signed-off-by: Sergey Temerkhanov Signed-off-by: Radha Mohan Chintakuntla
