Currently, when RECLAIM_INIT_CODE is set, the stacks are scaled to ensure that the entirety of the init section can be reclaimed as stack. This causes an issue in lib/psci/aarch64/psci_helpers.S, where the stack size is used for cache operations in psci_do_pwrdown_cache_maintenance(). If the stacks are scaled, then the PSCI code may fail to invalidate some of the stack memory before power down. Resizing stacks is also not good for stability in general, since code that works with a small number of cores may overflow the stack when the number of cores is increased. Change to make every stack be PLATFORM_STACK_SIZE big, and allow the total stack to be smaller than the init section. Any pages of the init section not reclaimed as stack will be set to read-only and execute-never, for security.

Usually, C has no problem up-converting types to larger bit sizes. MISRA rule 10.7 requires that you not do this, or be very explicit about this. This resolves the following required rule: bl1/aarch64/bl1_context_mgmt.c:81:[MISRA C-2012 Rule 10.7 (required)]<None> The width of the composite expression "0U | ((mode & 3U) << 2U) | 1U | 0x3c0U" (32 bits) is less that the right hand operand "18446744073709547519ULL" (64 bits). This also resolves MISRA defects such as: bl2/aarch64/bl2arch_setup.c:18:[MISRA C-2012 Rule 12.2 (required)] In the expression "3U << 20", shifting more than 7 bits, the number of bits in the essential type of the left expression, "3U", is not allowed. Further, MISRA requires that all shifts don't overflow. The definition of PAGE_SIZE was (1U << 12), and 1U is 8 bits. This caused about 50 issues. This fixes the violation by changing the definition to 1UL << 12. Since this uses 32bits, it should not create any issues for aarch32. This patch also contains a fix for a build failure in the sun50i_a64 platform. Specifically, these misra fixes removed a single and instruction, 92407e73 and x19, x19, #0xffffffff from the cm_setup_context function caused a relocation in psci_cpus_on_start to require a linker-generated stub. This increased the size of the .text section and caused an alignment later on to go over a page boundary and round up to the end of RAM before placing the .data section. This sectionn is of non-zero size and therefore causes a link error. The fix included in this reorders the functions during link time without changing their ording with respect to alignment.

And from crash_console_flush. We ignore the error information return by console_flush in _every_ place where we call it, and casting the return type to void does not work around the MISRA violation that this causes. Instead, we collect the error information from the driver (to avoid changing that API), and don't return it to the caller.

Implemented a parser which populates the properties of the CoT descriptors as per the binding document [1]. 'COT_DESC_IN_DTB' build option is disabled by default and can be enabled in future for all Arm platforms by making necessary changes in the memory map.

For Arm platforms SPs are loaded by parsing tb_fw_config.dts and adding them to SP structure sequentially, which in-turn is appended to loadable image list. With recently introduced dualroot CoT for SPs where they are owned either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID and Plat owned SPs index starts at SP_PKG5_ID. As the start index of SP depends on the owner, there should be a mechanism to parse owner of a SP and put it at the correct index in SP structure. This patch adds support for parsing a new optional field "owner" and based on it put SP details(UUID & Load-address) at the correct index in SP structure.

There was a collision between the name of the typedef in the CASSERT and something else, so we make the name of the typedef unique to the invocation of DEFFINE_SVC_UUID2 by appending the name that's passed into the macro. This eliminates the following MISRA violation: bl1/bl1_main.c:233:[MISRA C-2012 Rule 5.6 (required)] Identifier "invalid_svc_uuid" is already used to represent a typedef. This also resolves MISRA rule 5.9. These renamings are as follows: * tzram -> secram. This matches the function call name as it has sec_mem in it's name * fw_config_base -> config_base. This file does not mess with hw_conig, so there's little chance of confusion Change-Id: I8734ba0956140c8e29b89d0596d10d61a6ef351e Signed-off-by: Jimmy Brisson <jimmy.brisson@arm.com>

BL31 binary size is aligned to 4KB because of the code in include\plat\arm\common\arm_reclaim_init.ld.S: __INIT_CODE_UNALIGNED__ = .; . = ALIGN(PAGE_SIZE); __INIT_CODE_END__ = .; with all the zero data after the last instruction of BL31 code to the end of the page. This causes increase in size of BL31 binary stored in FIP and its loading time by BL2. This patch reduces the size of BL31 image by moving page alignment from __INIT_CODE_END__ to __STACKS_END__ which also increases the stack size for secondary CPUs.

Currently only single signing domain is supported for SP packages but there is plan to support dual signing domains if CoT is dualroot. SP_CONTENT_CERT_ID is the certificate file which is currently generated and signed with trusted world key which in-turn is derived from Silicon provider RoT key. To allow dual signing domain for SP packages, other certificate file will be derived from Platform owned RoT key. This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and does other related changes.

Our fdtw_read_cells() implementation goes to great lengths to sanity-check every parameter and result, but leaves a big hole open: The size of the storage the value pointer points at needs to match the number of cells given. This can't be easily checked at compile time, since we lose the size information by using a void pointer. Regardless the current usage of this function is somewhat wrong anyways, since we use it on single-element, fixed-length properties only, for which the DT binding specifies the size. Typically we use those functions dealing with a number of cells in DT context to deal with *dynamically* sized properties, which depend on other properties (#size-cells, #clock-cells, ...), to specify the number of cells needed. Another problem with the current implementation is the use of ambiguously sized types (uintptr_t, size_t) together with a certain expectation about their size. In general there is no relation between the length of a DT property and the bitness of the code that parses the DTB: AArch64 code could encounter 32-bit addresses (where the physical address space is limited to 4GB [1]), while AArch32 code could read 64-bit sized properties (/memory nodes on LPAE systems, [2]). To make this more clear, fix the potential issues and also align more with other DT users (Linux and U-Boot), introduce functions to explicitly read uint32 and uint64 properties. As the other DT consumers, we do this based on the generic "read array" function. Convert all users to use either of those two new functions, and make sure we never use a pointer to anything other than uint32_t or uint64_t variables directly. This reveals (and fixes) a bug in plat_spmd_manifest.c, where we write 4 bytes into a uint16_t variable (passed via a void pointer). Also we change the implementation of the function to better align with other libfdt users, by using the right types (fdt32_t) and common variable names (*prop, prop_names).

Currently our fdtw_read_array() implementation requires the length of the property to exactly match the requested size, which makes it less flexible for parsing generic device trees. Also the name is slightly misleading, since we treat the cells of the array as 32 bit unsigned integers, performing the endianess conversion. To fix those issues and align the code more with other DT users (Linux kernel or U-Boot), rename the function to "fdt_read_uint32_array", and relax the length check to only check if the property covers at least the number of cells we request. This also changes the variable names to be more in-line with other DT users, and switches to the proper data types. This makes this function more useful in later patches.

The platform io policies array is now always accessed through a fconf getter. This gives us an ideal spot to check for out-of-bound accesses. Remove the assertion in plat_get_image_source(), which is now redundant. Change-Id: Iefe808d530229073b68cbd164d927b8b6662a217 Signed-off-by: Sandrine Bailleux <sandrine.bailleux@arm.com>

This patch provides support for measured boot by adding calculation of BL2 image hash in BL1 and writing these data in TB_FW_CONFIG DTB. Change-Id: Ic074a7ed19b14956719c271c805b35d147b7cec1 Signed-off-by: Alexei Fedorov <Alexei.Fedorov@arm.com>

When SPD=spmd and SPMD_SPM_AT_SEL2=0, that is SPMC sits at S-EL1 then there is no need for TF-A to load secure partitions individually. In this configuration, SPMC handles secure partition loading at S-EL1/EL0 levels.
