The commit message from 2009 reports the reason behind this odd mixing of CPU and DWT registers. This feature got broken in 2017 with the introduction of the field struct reg::exist and its further use in the code. As result, the command 'reg' on a target Cortex-M reports only the core registers and then the header line ===== Cortex-M DWT registers not anymore followed by the DWT registers. Fix it by tagging each DWT registers as existing.

Normally, the CSU ROM will load boot.bin from the boot medium. However, when booting from JTAG we have to do this ourselves. There are generally two parts to this. First, we need to load the PMU firmware. Xilinx's tools do this by attaching to the PMU (a Microblaze CPU) over JTAG. However, the TAP is undocumented and we don't have any microblaze support in-tree. So instead we do it the same way FSBL does it: - We ask the PMU to halt - We load the firmware into the PMU RAM - We ask the PMU to resume The second thing we need to do is start one of the APU cores. When an APU is released from reset, it starts executing at the value of its RVBARADDR. While we could load the APU firmware over the AXI target, it is faster to load it over the APU target. To do this, we put the APU into an infinite loop before halting it. As an aside, I chose to use the "APU" terminology as opposed to "core" to make it clear that these commands operate on the A53 cores and not the R5F cores. Typical usage of these commands could look something like targets uscale.axi boot_pmu /path/to/pmu-firmware.bin boot_apu /path/to/u-boot-spl.bin But of course there is always the option to call lower-level commands individually if your boot process is more unusual.

On Cortex-M the same AP provides access to both CPU debug and CPU memory. This feature is not present on ARMv7a. To still keep some communality with ARMv7m code, the change [2] splits the CPU debug access from the CPU memory access by using two independent AP; this is copied from the system architecture of TI OMAP3530 which provides to DAP a direct AHB-AP memory bus on AP#0, separated from AP#1 for the APB-AP CPU debug. But the direct memory access through the system bus breaks the coherency between memory and CPU caches, so change [3] added some cache invalidation to avoid issues. The code to allow ARMv7a CPU to really read/write in CPU memory was added by change [4] in 2011. Such still not optimized implementation was very slow, so it did not replace the access through the system bus. A selection through DAP's 'apsel" command was used to select between the two modes. Only in 2015, with change [5], the speed of CPU read/write was improved using the DCC_FAST_MODE. But the direct access to the memory through the system bus remained. Finally, with change [6] in 2018 the system bus access was dropped for good, as the new virtual target "mem_ap" could implement such access in a more clean way. Only memory access through CPU remained for ARMv7a. Nevertheless, a useless cache invalidation remained in the code, decreasing the speed of the write access. Drop the useless cache invalidate on CPU memory write and the associated comment, not anymore valid. Drop the now unused function armv7a_cache_auto_flush_on_write(). This provides a speedup of between 4 and 8, depending on adapter and JTAG/SWD speed.

This was probably a way to test the cache handling when there were still the two independent accesses for APB-AP CPU debug and for AHB-AP memory bus. The handling of cache for cortex_a is robust and there is no more reason to disable it. The command 'cache auto' is not used in any upstream script. On target aarch64 this command has never been introduced as the cache is always handled automatically by OpenOCD. Drop the command 'cache auto' and add it in the deprecated list. Drop the flag 'auto_cache_enabled' by considering it as true. Rename the function 'armv7a_cache_auto_flush_all_data()' as 'armv7a_cache_flush_all_data()' and, while there, fix the error propagation in SMP case.

Most clang builds set __GNUC__/__GNUC_MINOR__ to 4.2 for historical reasons, so they don't trigger this condition; however, some builds set it to something much higher to work around code using __GNUC__ to determine if a feature that does exist in clang (but not gcc 4.2) is available, causing OpenOCD to use attribute gnu_printf. The problem can be reproduced without a special clang build by adding -fgnuc-version=14.1 to CFLAGS.
