2019-01-04	09d40e0 Browse files » Sanitise includes across codebase ... Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

2018-11-08	c3cf06f Browse files » Standardise header guards across codebase ... All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com> Antonio Nino Diaz committed on 8 Nov 2018

Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Sun Sep 16 11:52:37 2018 -0700 Linux 4.19-rc4 Overview --------- BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered at this exception level (the Renesas' ATF reference tree [1] resets into EL1 before entering BL2 - see its bl2.ld.S) BL2 initializes DDR (and i2c to talk to the PMIC on some platforms) before determining the boot reason (cold or warm). During suspend all CPUs are switched off and the DDR is put in backup mode (some kind of self-refresh mode). This means that BL2 is always entered in a cold boot scenario. Once BL2 boots, it determines the boot reason, writes it to shared memory (BOOT_KIND_BASE) together with the BL31 parameters (PARAMS_BASE) and jumps to BL31. To all effects, BL31 is as if it is being entered in reset mode since it still needs to initialize the rest of the cores; this is the reason behind using direct shared memory access to BOOT_KIND_BASE and PARAMS_BASE instead of using registers to get to those locations (see el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use case). Depending on the boot reason BL31 initializes the rest of the cores: in case of suspend, it uses a MBOX memory region to recover the program counters.
