Suppress spurious deprecated declaration warnings
2018-03-02Remove sp_min functions from plat_common.cSoby Mathew
This patch removes default platform implementations of sp_min platform APIs from plat/common/aarch32/plat_common.c. The APIs are now implemented in `plat_sp_min_common.c` file within the same folder. The ARM platform layer had a weak definition of sp_min_platform_setup2() which conflicted with the weak definition in the common file. Hence this patch fixes that by introducing a `plat_arm_` version of the API thus allowing individual boards within ARM platforms to override it if they wish to.

2018-03-01Emit warnings when using deprecated GIC initDan Handley
Emit runtime warnings when intializing the GIC drivers using the deprecated method of defining integer interrupt arrays in the GIC driver data structures; interrupt_prop_t arrays should be used instead. This helps platforms detect that they have migration work to do. Previously, no warning was emitted in this case. This affects both the GICv2 and GICv3 drivers. Also use the __deprecated attribute to emit a build time warning if these deprecated fields are used. These warnings are suppressed in the GIC driver compatibility functions but will be visible if platforms use them.

2018-03-01Improve MULTI_CONSOLE_API deprecation warningsDan Handley
For platforms that have not migrated to MULTI_CONSOLE_API == 1, there are a lot of confusing deprecated declaration warnings relating to use of console_init() and console_uninit(). Some of these relate to use by the generic code, not the platform code. These functions are not really deprecated but *removed* when MULTI_CONSOLE_API == 1. This patch consolidates these warnings into a single preprocessor warning. The __deprecated attribute is removed from the console_init() and console_uninit() declarations. For preprocessor warnings like this to not cause fatal build errors, this patch adds -Wno-error=cpp to the build flags when ERROR_DEPRECATED == 0. This option (and -Wno-error=deprecated-declarations) is now added to CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the assembler as well as the compiler. This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED build flags by defaulting MULTI_CONSOLE_API to 0 instead of ERROR_DEPRECATED. This allows platforms that have not migrated to MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful build error. Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since the AArch32 console implementation does not support MULTI_CONSOLE_API == 1.

2018-02-27EHF: Introduce preempted return code parameter to ehf_allow_ns_preemption()Jeenu Viswambharan
When a Yielding SMC is preempted, it's possible that Non-secure world is resumed afterwards. In this case, Non-secure execution would find itself in a state where the SMC has returned. However, the dispatcher might not get an opportunity to populate the corrected return code for having been preempted, and therefore the caller of the Yielding SMC cannot reliably determine whether the SMC had successfully completed or had been preempted. To solve this, this patch introduces a new parameter to the ehf_allow_ns_preemption() API. An SPD, through this parameter, would provide the expected error code when a Yielding SMC is preempted. EHF can then populate the specified value in x0 of the Non-secure context so that the caller of the Yielding SMC correctly identifies the SMC return as a preemption. Documentation updates to follow.

2018-02-27Add comments about mismatched TCR_ELx and xlat tablesAntonio Nino Diaz
When the MMU is enabled and the translation tables are mapped, data read/writes to the translation tables are made using the attributes specified in the translation tables themselves. However, the MMU performs table walks with the attributes specified in TCR_ELx. They are completely independent, so special care has to be taken to make sure that they are the same. This has to be done manually because it is not practical to have a test in the code. Such a test would need to know the virtual memory region that contains the translation tables and check that for all of the tables the attributes match the ones in TCR_ELx. As the tables may not even be mapped at all, this isn't a test that can be made generic. The flags used by enable_mmu_xxx() have been moved to the same header where the functions are. Also, some comments in the linker scripts related to the translation tables have been fixed.

2018-02-26ARM Platforms: Load HW_CONFIG in BL2Soby Mathew
The patch adds the necessary changes to load HW_CONFIG in BL2 for ARM Platforms : 1. The load address of HW_CONFIG is specified via the `hw_config_addr` property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size` property defines the maximum size to be expected for the HW_CONFIG. The `arm_dyn_cfg_helpers.c` and corresponding header implements utility functions to parse these DT properties defined. The `arm_dyn_cfg.c` implements wrappers to these helpers to enable them to be invoked from ARM platform layer. 2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is the list of images to be loaded by BL2. 3. The `libfdt` sources are now included when BL2 is built 4. A new helper `populate_next_bl_params_config()` is introduced in desc_image_load.c to populate the subsequent executable BL images with the `hw_config` and the corresponding `fw_config` if available. The `plat_get_next_bl_params()` API for ARM platforms is modified to invoke this new helper. 5. The implementation of `bl2_early_platform_setup2()` is modified to consider `arg0` as well in addition to `arg1` passed from BL1. 6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt. Change-Id: I80f1554adec41753e0d179a5237364f04fe13a3f Signed-off-by: Soby Mathew <soby.mathew@arm.com>
2018-02-26ARM Platorms: Load TB_FW_CONFIG in BL1Soby Mathew

The fvp_io_storage.c and arm_io_storage.c also adds entries corresponding to TB_FW_CONFIG. A helper function `arm_load_tb_fw_config()` is added to load and authenticate TB_FW_CONFIG if present.

2018-02-26Introduce the new BL handover interfaceSoby Mathew
This patch introduces a new BL handover interface. It essentially allows passing 4 arguments between the different BL stages. Effort has been made so as to be compatible with the previous handover interface. The previous blx_early_platform_setup() platform API is now deprecated and the new blx_early_platform_setup2() variant is introduced. The weak compatiblity implementation for the new API is done in the `plat_bl_common.c` file. Some of the new arguments in the new API will be reserved for generic code use when dynamic configuration support is implemented. Otherwise the other registers are available for platform use.

2018-02-26Add image_id to bl1_plat_handle_post/pre_image_load()Soby Mathew
This patch adds an argument to bl1_plat_post/pre_image_load() APIs to make it more future proof. The default implementation of these are moved to `plat_bl1_common.c` file. These APIs are now invoked appropriately in the FWU code path prior to or post image loading by BL1 and are not restricted to LOAD_IMAGE_V2. The patch also reorganizes some common platform files. The previous `plat_bl2_el3_common.c` and `platform_helpers_default.c` files are merged into a new `plat_bl_common.c` file. NOTE: The addition of an argument to the above mentioned platform APIs is not expected to have a great impact because these APIs were only recently added and are unlikely to be used.

2018-02-15Redefine SMC_UNK as -1 instead of 0xFFFFFFFFAntonio Nino Diaz
According to the SMC Calling Convention (ARM DEN0028B): The Unknown SMC Function Identifier is a sign-extended value of (-1) that is returned in R0, W0 or X0 register. The value wasn't sign-extended because it was defined as a 32-bit unsigned value (0xFFFFFFFF). SMC_PREEMPT has been redefined as -2 for the same reason. NOTE: This might be a compatibility break for some AArch64 platforms that don't follow the previous version of the SMCCC (ARM DEN0028A) correctly. That document specifies that only the bottom 32 bits of the returned value must be checked. If a platform relies on the top 32 bits of the result being 0 (so that SMC_UNK is 0x00000000FFFFFFFF), it will have to fix its code to comply with the SMCCC.

2018-02-02zlib: add gunzip() supportMasahiro Yamada
This commit adds some more files to use zlib from TF. To use zlib, ->zalloc and ->zfree hooks are needed. The implementation depends on the system. For user-space, the libc provides malloc() and friends. Unfortunately, ARM Trusted Firmware does not provide malloc() or any concept of dynamic memory allocation. I implemented very simple calloc() and free() for this. Stupidly, zfree() never frees memory, but it works enough for this. The purpose of using zlib is to implement gunzip() - this function takes compressed data from in_buf, then dumps the decompressed data to oub_buf. The work_buf is used for memory allocation during the decompress. Upon exit, it updates in_buf and out_buf. If successful, in_buf points to the end of input data, out_buf to the end of the decompressed data. To use this feature, you need to do: - include lib/zlib/zlib.mk from your platform.mk - add $(ZLIB_SOURCES) to your BL*_SOURCES Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
