2017-04-02io: Allow image load to address zeroKonstantin Porotchkin
Allow zero-address assertion bypass if requested by platform compilation flag PLAT_ALLOW_ZERO_ADDR_COPY. This patch allows loading BL33 (u-boot) to address 0x0 Change-Id: I10518db13466017110358437790ce5212d52d9e6 Signed-off-by: Haim Boot <hayim@marvell.com> Signed-off-by: Konstantin Porotchkin <kostap@marvell.com> Reviewed-on: http://vgitil04.il.marvell.com:8080/37914

2015-11-02Remove deprecated IO return definitionsJuan Castillo
Patch 7e26fe1f deprecates IO specific return definitions in favour of standard errno codes. This patch removes those definitions and its usage from the IO framework, IO drivers and IO platform layer. Following this patch, standard errno codes must be used when checking the return value of an IO function. Change-Id: Id6e0e9d0a7daf15a81ec598cf74de83d5768650f
2015-06-25Use numbers to identify images instead of namesJuan Castillo
The Trusted firmware code identifies BL images by name. The platform port defines a name for each image e.g. the IO framework uses this mechanism in the platform function plat_get_image_source(). For a given image name, it returns the handle to the image file which involves comparing images names. In addition, if the image is packaged in a FIP, a name comparison is required to find the UUID for the image. This method is not optimal. This patch changes the interface between the generic and platform code with regard to identifying images. The platform port must now allocate a unique number (ID) for every image. The generic code will use the image ID instead of the name to access its attributes. As a result, the plat_get_image_source() function now takes an image ID as an input parameter. The organisation of data structures within the IO framework has been rationalised to use an image ID as an index into an array which contains attributes of the image such as UUID and name. This prevents the name comparisons. A new type 'io_uuid_spec_t' has been introduced in the IO framework to specify images identified by UUID (i.e. when the image is contained in a FIP file). There is no longer need to maintain a look-up table [iname_name --> uuid] in the io_fip driver code. Because image names are no longer mandatory in the platform port, the debug messages in the generic code will show the image identifier instead of the file name. The platforms that support semihosting to load images (i.e. FVP) must provide the file names as definitions private to the platform. The ARM platform ports and documentation have been updated accordingly. All ARM platforms reuse the image IDs defined in the platform common code. These IDs will be used to access other attributes of an image in subsequent patches. IMPORTANT: applying this patch breaks compatibility for platforms that use TF BL1 or BL2 images or the image loading code. The platform port must be updated to match the new interface.

2015-03-16Add macro to calculate number of elements in an arrayVikram Kanigiri
This patch defines the ARRAY_SIZE macro for calculating number of elements in an array and uses it where appropriate. Change-Id: I72746a9229f0b259323972b498b9a3999731bc9b
2015-01-28TBB: authenticate BL3-x images and certificatesJuan Castillo
This patch adds support to authenticate the Trusted Key certificate and the BL3-x certificates and images at BL2. Change-Id: I69a8c13a14c8da8b75f93097d3a4576aed71c5dd
2015-01-28TBB: authenticate BL2 image and certificateJuan Castillo
This patch adds support to authenticate the BL2 content certificate and image using the authentication module in BL1. The FIP driver has been extended to include the BL2 certificate UUID. FVP and Juno ports include the BL2 certificate FIP file definition. Change-Id: I32680e9bd123c8db4a4193c14448c9b32b0e9325
2014-08-12Rationalize console log outputDan Handley
Fix the following issues with the console log output: * Make sure the welcome string is the first thing in the log output (during normal boot). * Prefix each message with the BL image name so it's clear which BL the output is coming from. * Ensure all output is wrapped in one of the log output macros so it can be easily compiled out if necessary. Change some of the INFO() messages to VERBOSE(), especially in the TSP. * Create some extra NOTICE() and INFO() messages during cold boot. * Remove all usage of \r in log output. Fixes ARM-software/tf-issues#231 Change-Id: Ib24f7acb36ce64bbba549f204b9cde2dbb46c8a3
2014-07-10Add support for BL3-0 imageSandrine Bailleux
- Add support for loading a BL3-0 image in BL2. Information about memory extents is populated by platform-specific code. Subsequent handling of BL3-0 is also platform specific. The BL2 main function has been broken down to improve readability. The BL3-2 image is now loaded before the BL3-3 image to align with the boot flow. - Build system: Add support for specifying a BL3-0 image that will be included into the FIP image. - IO FIP driver: Add support for identifying a BL3-0 image inside a FIP image. - Update the documentation to reflect the above changes.

2014-05-23Split platform.h into separate headersDan Handley
Previously, platform.h contained many declarations and definitions used for different purposes. This file has been split so that: * Platform definitions used by common code that must be defined by the platform are now in platform_def.h. The exact include path is exported through $PLAT_INCLUDES in the platform makefile. * Platform definitions specific to the FVP platform are now in /plat/fvp/fvp_def.h. * Platform API declarations specific to the FVP platform are now in /plat/fvp/fvp_private.h. * The remaining platform API declarations that must be ported by each platform are still in platform.h but this file has been moved to /include/plat/common since this can be shared by all platforms.

2014-05-22Allow BL3-2 platform definitions to be optionalDan Handley
The generic image loading and IO FIP code no longer forces the platform to create BL3-2 (Secure-EL1 Payload) specific definitions. The BL3-2 loading code in bl2/bl2main.c is wrapped by a #ifdef BL32_BASE blocks, allowing the BL3-2 definitions to be optional. Similarly for the name_uuid array defintion in drivers/io/io_fip.c. Also update the porting guide to reflect this change. The BL3-2 platform definitions remain non-configurably present in the FVP port. Fixes ARM-software/tf-issues#68 Change-Id: Iea28b4e94d87a31f5522f271e290919a8a955460
2014-05-06Remove variables from .data sectionDan Handley
Update code base to remove variables from the .data section, mainly by using const static data where possible and adding the const specifier as required. Most changes are to the IO subsystem, including the framework APIs. The FVP power management code is also affected. Delay initialization of the global static variable, next_image_type in bl31_main.c, until it is realy needed. Doing this moves the variable from the .data to the .bss section. Also review the IO interface for inconsistencies, using uintptr_t where possible instead of void *. Remove the io_handle and io_dev_handle typedefs, which were unnecessary, replacing instances with uintptr_t. Fixes ARM-software/tf-issues#107. Change-Id: I085a62197c82410b566e4698e5590063563ed304
2014-05-06Reduce deep nesting of header filesDan Handley
Reduce the number of header files included from other header files as much as possible without splitting the files. Use forward declarations where possible. This allows removal of some unnecessary "#ifndef __ASSEMBLY__" statements. Also, review the .c and .S files for which header files really need including and reorder the #include statements alphabetically. Fixes ARM-software/tf-issues#31 Change-Id: Iec92fb976334c77453e010b60bcf56f3be72bd3e
2014-05-06Always use named structs in header filesDan Handley
Add tag names to all unnamed structs in header files. This allows forward declaration of structs, which is necessary to reduce header file nesting (to be implemented in a subsequent commit). Also change the typedef names across the codebase to use the _t suffix to be more conformant with the Linux coding style. The coding style actually prefers us not to use typedefs at all but this is considered a step too far for Trusted Firmware. Also change the IO framework structs defintions to use typedef'd structs to be consistent with the rest of the codebase. Change-Id: I722b2c86fc0d92e4da3b15e5cab20373dd26786f
2014-05-06Make use of user/system includes more consistentDan Handley
Make codebase consistent in its use of #include "" syntax for user includes and #include <> syntax for system includes. Fixes ARM-software/tf-issues#65 Change-Id: If2f7c4885173b1fd05ac2cde5f1c8a07000c7a33
2014-03-21Fix file_to_uuid() functionSandrine Bailleux
This patch fixes a bug in the 'file_to_uuid()' function: it used to cause an exception by dereferencing a null pointer when a given UUID was not found in the UUID array. The fix is to delete the final null entry in the UUID array, which is not needed because the array is statically declared so its size is known at build time. Fixes ARM-software/tf-issues#43 Change-Id: I0a003485b88134564c0d36f57c274215d9e16532
2014-02-20Report recoverable errors as warningsJeenu Viswambharan
At present many recoverable failures are reported as errors. This patch modifies all such failures to be reported as warnings instead. Change-Id: I5141653c82498defcada9b90fdf7498ba496b2f2
2014-02-20Fix FIP offset address when file not foundJeenu Viswambharan
If there is a request to open a file from FIP, and that file is not found, the driver fails to reset the offset address. This causes subsequent file loads to fail. This patch resets the offset address to zero if a file is not found so that subsequent file loads are unaffected. Change-Id: I16418e35f92fb7c85fb12e2acc071990520cdef8
2014-02-17Add Firmware Image Package (FIP) driverHarry Liebel
The Firmware Image Package (FIP) driver allows for data to be loaded from a FIP on platform storage. The FVP supports loading bootloader images from a FIP located in NOR FLASH. The implemented FVP policy states that bootloader images will be loaded from a FIP in NOR FLASH if available and fall back to loading individual images from semi-hosting. NOTE: - BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured to run from the BL33_BASE address. This is currently set to DRAM_BASE+128MB for the FVP.
