What it describes is booting and unsigned TF-A. A very brief section has been added on signing BL2 which is in no-way comprehensive.

	ba597da Browse files » Support shared Mbed TLS heap for FVP ... This patch introduces the shared Mbed TLS heap optimisation for Arm platforms. The objective is the Mbed TLS heap to be shared between BL1 and BL2 so as to not allocate the heap memory twice. To achieve that, the patch introduces all the necessary helpers for implementing this optimisation. It also applies it for FVP.

	6d01a46 Browse files » Prepare Mbed TLS drivers for shared heap ... The Mbed TLS drivers, in order to work, need a heap for internal usage. This heap, instead of being directly referenced by the drivers, now it is being accessed indirectly through a pointer. Also, the heap, instead of being part of the drivers, now it is being received through the plat_get_mbedtls_heap() function. This function requests a heap from the current BL image which utilises the Mbed TLS drivers. Those changes create the opportunity for the Mbed TLS heap to be shared among different images, thus saving memory. A default heap implementation is provided but it can be overridden by a platform specific, optimised implemenetation.

	0c62883 Browse files » backtrace: Introduce backtrace function ... This function diplays the backtrace, the current EL and security state to allow a post-processing tool to choose the right binary to interpret the dump. The output can be fed to GNU addr2line to resolve function names given an ELF binary compiled with debug information. The "-i" flag is recommended to improve display in case of inlined functions. The *.dump files generated during the build process can also be used. The function works in AArch64 and AArch32. In AArch32 it only works in A32 mode (without T32 interworking), which is enforced in the Makefile. Sample output of a backtrace at EL3: BACKTRACE: START: function_name 0: EL3: 0x798 1: EL3: 0x538 2: EL3: 0x550 3: EL3: 0x55c 4: EL3: 0x568 5: EL3: 0x5a8 6: EL3: 0xf4 BACKTRACE: END: function_name In order to enable it the new option ENABLE_BACKTRACE must be set to 1. This option is set to 1 by default only in AArch64 debug builds. As usual, it can be overridden by the platform makefile and in the build command line.

	8fd9d4d Browse files » Allow manually setting the AArch32 instruction set ... At the moment the AArch32 instruction set isn't specified in the command line, which means that the compiler is free to choose the one it sees fit. This decision may change between compiler versions, so it is better to specify it manually. The build option AARCH32_INSTRUCTION_SET has been introduced for this reason. This option can be set to T32 or A32 to pass the correct flags to the compiler. The current behaviour is to default to T32 due to it's smaller size.

2018-08-29	24f671f Browse files » context_mgmt: Fix HANDLE_EA_EL3_FIRST implementation ... This patch fixes a bug in the context management code that causes it to ignore the HANDLE_EA_EL3_FIRST compile-time option and instead always configure SCR_EL3 to force all external aborts to trap into EL3. The code used #ifdef to read compile-time option declared with add_define in the Makefile... however, those options are always defined, they're just defined to either 0 or 1, so #if is the correct syntax to check for them. Also update the documentation to match. This bug has existed since the Nov 2017 commit 76454abf4 (AArch64: Introduce External Abort handling), which changed the HANDLE_EA_EL3_FIRST option to use add_define.

2018-08-20	5f83591 Browse files » AArch64: Enable MPAM for lower ELs ... Memory Partitioning And Monitoring is an Armv8.4 feature that enables various memory system components and resources to define partitions. Software running at various ELs can then assign themselves to the desired partition to control their performance aspects. With this patch, when ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows lower ELs to access their own MPAM registers without trapping to EL3. This patch however doesn't make use of partitioning in EL3; platform initialisation code should configure and use partitions in EL3 if required.
