2023-11-02commonlib/fsp_relocate: Fix potential NULL pointer dereferenceJeremy Compostella
Commit 1df1cf994aa9 ("commonlib/fsp_relocate: add PE32 section support") introduced a potential NULL pointer dereference if there is PE32 binary to relocate outside of the first firmware volume. The `fih_offset' pointer was used as an output variable but now it is also used as an input variable to pass the FSP information header to the `pe_relocate()' function. This commit resolves this potential NULL-pointer dereference by passing the pointer systematically and without affecting the logic as it is only set if it has not been set before.

Similarly to te_relocate(), on success pe_relocate() should return 0. It has never been an issue so far as pe_relocate() return value is not tested.

2022-11-25commonlib/fsp_relocate.c: Fix cbfstool build on 32-bit hostWerner Zeh
On a 32-bit host, uintptr_t is defined as 'unsigned int' instead of 'unsigend long int' like on a 64-bit host. When cbfstool is built on a 32-bit host, the printk format specifier '%lx' expects a 'long int' while new_addr is of type 'uintptr_t', aka 'unsigned int'. This in the end leads to a build error. To fix this and make it build on both, 32- and 64-bit hosts, use PRIxPTR as the format specifier. This macro will be resolved at compile time in the right way on both, 32- and 64-bit hosts. Test=Build cbfstool on 32- and 64-bit hosts.

2022-09-24commonlib/fsp_relocate: add PE32 section supportEddie Vas
Recently published Intel CedarIslandFSP binary contains PE images in FSP-M and FSP-S. This causes coreboot boot hang on DeltaLake servers. PI spec PI_Spec_1_7_final_Jan_2019 on uefi.org talks about FV files requiring to support SECTION_PE32 sections and FSP specification states that FSP images are created in alignment with PI specification. FSP images are relocated at build time and run time using the func fsp_component_relocate. That code only supported TE image relocation so far. The change required to add support for pe_relocate in fsp-relocate.c I had to move a few functions to top of file as they need to be used by pe_relocate but were placed below the te_relocate function. I chose to place pe_relocate function next to te_relocate. The code supports PE32 format, not PE32+, at this time. Links for PE and FSP specs are provided below for reference. Link= https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/fsp-architecture-spec-v2.pdf Link= https://uefi.org/sites/default/files/resources/PI_Spec_1_7_final_Jan_2019.pdf TESTED= This code is tested with FSP version 33A for DeltaLake boot which has FSP-M and FSP-S as PE32 sections. This FSP version does not boot on DeltaLake without this change.

Allow FSP1.1 driver to still call fsp1_1_relocate which acts as a wrapper for fsp_component_relocate.
